Japanese Saws: The Dozuki Saw

Christ in the House of His Parents by John Everett Millais

It is the accuracy and detail inherent in crafted goods that endows them with lasting value. It is the time and attention paid by the carpenter, the seamstress and the tailor that makes this detail possible.

Tim Jackson

This post is about a variety of handsaw unique to Japan called the “Dozuki Nokogiri.”


Dozuki saw is pronounced doh/zoo/kee – noh/koh/gee/ri and is written 胴付鋸 in Chinese characters. The first character means “trunk.” or “torso.” The second character means to “attach” something. The third character means “saw.” It’s a thin-bladed, fine-toothed, single-edged crosscut saw with a steel back specialized for making precise, shallow cuts in wood, especially tenon shoulders. Dozuki are not intended for ripping tenons or cutting dovetails, although they can do both fairly well.

Along with the Hozohiki saw, this is the thinnest and most precise variety of Japanese saws, and some, including your humble servant, would say it is the most precise type of saw made anywhere in the world. Certainly, it is the most difficult to make properly.

The Dozuki was the first Japanese saw that became well-known outside of Japan. As many thousands of woodworkers around he world can attest, if you need to make clean, precise, shallow crosscuts, then the Dozuki is a must-have tool.

A variant of the Dozuki is the “Handozuki” meaning “half dozuki.” Handozuki do not have a back steel, but have a slightly thicker and stiffer blade than a normal dozuki, but even then, they are flimsy and more difficult to use than a standard Dozuki. The lack of a back steel, however, allows them to make very precise crosscuts in material where the back steel of a standard dozuki would get in the way. Handozuki were once common, but are seldom seen nowadays.

I have previously written about another variety of Japanese saw with a back steel called the “hozohiki” or “tenon cutter saw.” This type of saw is nearly identical to a Dozuki, although sometimes the blade is shaped slightly different. In any case, it always has rip teeth and excels at cutting precision joints with the grain.

If the Dozuki has a shortcoming, it is the delicate nature of their teeth, which can break when cutting harder woods in a ham-handed manner. Bigger teeth have a larger cross section of steel and are more resistant to breaking than smaller teeth, so it is wise to match the thickness of the Dozuki’s plate and size of its teeth to the hardness of the wood and the user’s sawing skills. In this regard, Western saws with their thicker plates and relatively blunter teeth are much tougher, and in many cases, better suited to cutting harder woods. It’s too bad their precision is often poor.

Using the Dozuki Saw

The proper technique for using a dozuki is to mark the cut with a sharp marking knife and to cut to the line. Goes without saying, right? Perhaps not, because many woodworking gurus in the West advocate first making sawcuts offset from the layout lines and then paring to the layout line using a chisel or a shoulder plane.

While such obviously inefficient techniques may be necessary when using Western backsaws with their thick plates, dull teeth, and excessive set, they are seen by Japanese woodworkers, accustomed to using Dozuki saws, as slow and amateurish.

I strongly encourage Gentle Readers to tune and sharpen their saws and train themselves to cut precisely to the layout line first time, every time.

There are easily-made, simple wooden guides one can use to make this process quicker, but the ultimate guide is a good saw combined with eyes and hands working together confidently. Perhaps I can address the subject of cutting guides and jigs in another article.

As your humble servant mentioned above, the tiny teeth of Dozuki saws are fragile and do not endure ham-handed abuse well. It is recommended that Gentle readers new to the Dozuki saw become accustomed to using it in soft woods such as White Pine before attempting to make a piano from ebony.

Sawteeth are too often damaged by inadvertently banging them against hard objects like a chisel, another saw, or a concrete floor. Please be careful.

Other common causes of damaged sawteeth are forcing the saw too hard, a brutish habit the gods of handsaws frown upon mightily, or swinging the saw left and right in the cut causing the tender teeth to snag on the entrance and exit to the kerf, bending and even breaking them. This last cause of damage is perhaps understandable but still about as intelligent as eating boogers. If you are afflicted with any of these unfortunate habits (especially gnoshing on “nose ‘taters”), please make a conscious effort to train them out of your life.

The first bad habit of using excessive force can be easily remedied by simply not pressing down on the saw. Back saws, including both the Dozuki and Western varieties have a steel back that applies downward pressure automatically. You cannot improve on this, so don’t even try.

Using the proper grip can help too. A good rule when using a Dozuki or Hozohiki saws to make precise cuts is to extend the pinkie finger so it is not touching the handle. This makes it much easier to control the downward force your hand puts into the saw. Don’t worry, this grip will not make anyone mistake you for a lady of refinement, unless you are wearing a pretty pink woodworking apron with frilly lace, that is. (ツ)

I like to extend my index finger along the top of the handle because I find this helps me feel the direction of the cut. Your mileage will not vary.

I also like to pinch the saw lightly between the first knuckle of my middle finger and the pad of the thumb forming a single pivot point which helps to keep the saw in proper alignment.

While perhaps a tad anthropomorphic, understanding the following three points about handsaw psychology is absolutely helpful when making precise cuts with any handsaw, or at least that’s what my saws tell me:

  1. A saw cuts because it wants to cut (not because you are strong or clever);
  2. A saw cuts well because it is true and sharp (not because you are strong or clever);
  3. Get out if it’s way (because you’re not as strong or clever as you think).

The first point is a simple acknowledgment of the nature of the saw, it’s motivations, and your relationship with it. Perfection is unattainable.

The second point is an essential truth of the saw, one many people never understand. Most problems with handsaws can be resolved by truing the plate (an extremely common problem among neglected and/or abused handsaws) and sharpening the teeth. If you fail in this basic duty, your saw will neither be happy nor will it serve you well. Would that humans were as easy to fix.

It all comes together in the third point because, once we understand the nature and truth of the handsaw, and have dutifully made it’s bright blade true and its vicious little teeth sharp, then we must forget how strong and clever we are, get out of its way, and let our slender buddy do its job.

And just how do we get out of a saw’s way? I just knew you were going to ask:

  1. Keep the saw moving in the right direction. Not as easy as it sounds. But remember, a well-made handsaw is a simple-minded beastie that wants to move in a straight line, so if it doesn’t, it’s your fault;
  2. Rely on the weight of the blade and its back alone to apply adequate pressure (not thy mighty arm, Oh God of Thunder);
  3. Keep your wrist loose and actively rotate it (this is important) so the sawblade moves to and fro only, not side to side. If you lock your wrist, the blade will unavoidably swing right and left and up and down in the cut, hindering the faithful saw, and buggering the precision of the cut it wants to make. This technique requires practice to learn. Do it.
  4. Focus on the sawkerf; Encourage your sharp little buddy to cut true. Banish all distractions, including that bench cat swanning around demanding its lazy servant (that’s you) provide it savory snacks. Using a Dozuki saw is a meditative process. Indeed, an occasional prayer to the gods of handsaws can never go amiss.

The C&S Dozuki Saw

We have a special Dozuki hand-made to meet the severe demands of our professional Beloved Customers. Like our Hozohiki saws, it too is hand-forged from Hitachi Metal’s Yasuki Shirogami No.2 high-carbon steel by Nakaya Takijiro, an extremely skilled craftsman, and one the very few traditional sawsmiths left in Japan. Takijiro hand-scrapes the plate to the proper double-taper to prevent binding, hammer tensions the blade to stiffen it and to prevent it from warping and binding as it heats up in-use, and hand-cuts, hand-files and hammer-sets the teeth.

Very few saws are still being produced to this level of quality and with these performance characteristics. If you need a professional-grade high-precision saw that prioritizes performance over appearance, one that will not get in your way but will help you do better work, then these will be available in limited quantities for a limited time. Unlike you and me, Takijiro is not getting a little younger everyday.

The Ogre and the Blacksmith

The Blacksmith and his daughter

The following is an old tale from Japan’s Toyama Prefecture. It’s not exactly a Christmas story, but includes all the classical elements a story shared on a cold winter’s eve must have: A beautiful maiden, a cranky blacksmith, an elemental creature, magic, weapons of death and destruction, an impossible challenge, and of course…, chickens. I hope you enjoy it.

Long long ago and far far away in a country in Japan called Etchu (modern day Toyama Prefecture) there was a large blacksmith’s shop.

The owner of the smithy, called “Master Blacksmith,” was well-to-do with many craftsmen working for him. He lived in a big house called a chouja.

The Hagiwara Chouja

Master Blacksmith had a single daughter of marriageable age, a rare beauty with almond eyes and long black hair shiny as a raven’s wing.

One day he announced to all the craftsmen in the area that he would give the hand of this daughter to the first suitor to forge 1,000 spearheads in a single night.

A classical Japanese “straight spear” (直槍) spearhead, distinctly different from most Western spears.
A “Cross” spearhead (十文字槍) used to thrust, parry blows and pull horsemen to the ground, a difficult piece of work for the blacksmith to forge, and infamous for turning the fingers of professional sharpeners sticky red (seriously). 

But no matter how skilled, every weapons blacksmith knows that it’s impossible to forge 1,000 spearheads in a single night, so his challenge went unanswered.

Master Blacksmith decided he needed to expand his offer and so put up a notice board describing his challenge alongside the main road for passersby to see, and waited for skilled craftsmen to appear.


Lo and behold an ogre that lived on a nearby mountain meandered by late one night and saw the notice. It did a little jig the way happy ogres do and gleefully exclaimed “Ha ha hee heee! A thousand spearheads is easy for meee!

The next morning, using the elemental magic that many ogres have, it changed his appearance to that of a young man and went down the mountain to Master Blacksmith’s house.

The Master looked doubtfully at the ogre in the shape of a young man and disdainfully said “What makes a young fella like you think he can make a thousand spearheads in one night?”

The ogre responded, “I can do it. I will surely make them before the cock crows in the morning.”

Thinking he had nothing to loose, the Master responded: “Then make them if you can.”

As the sun went down, the ogre in the shape of a young man went into the smithy, closed the doors, and began working.

Master Blacksmith heard sounds like the wind blowing from inside his smithy, but nary the sound of  a hammer striking metal or the ringing of an anvil. Perplexed, he said to himself “What can he be doing in there?”

Slipping quietly around to the back of his smithy and peeking through a crack in the siding boards, Master Blacksmith was shocked as he had never been shocked before because he saw fire spewing from the young man’s mouth as he bent and folded and shaped yellow-hot steel in his bare hands like it was warm taffy!

Before his eyes a smoking stack of completed spearheads quickly grew. It became obvious to Master Blacksmith that all 1,000 spearheads would be finished well before dawn.

Fearful for his tender daughter, Master Blacksmith realized he had to do something to stop the strange young man from successfully completing the challenge, so he thought and thought and thought until his thinker overheated.

“The only way out of this mess I have made is for the cock to crow before all 1,000 spearheads are completed,” he eventually reasoned. Following this logic to it’s natural conclusion, he took a jar of hot water into the chicken coop where the chickens were all fast asleep dreaming of stretchy worms and crunchy beetles.

Desperate to make even a single chicken crow, he poured the hot water on the roost where the chickens slept soundly. The surprised chickens all woke at once in a panic with the hens squacking, cackling, and screaming while the roosters all crowed out “Cock-a-doodly dooooo!”

Hearing this racket from the chicken coop the ogre in the form of a young man became frightened, wailing out “I have been discovered!”

Instantly, the magic that had changed its appearance popped like a soap bubble revealing the ogre’s supernatural red skin, yellow horns, and shiny white fangs again. The ogre ran out of the smithy like ten stampeding bulls raising a cloud of smoke all the way back to the mountain where it came from never to be seen again. 

With this, the blacksmith rubbed his chest and exclaimed in relief “I see, he was an ogre after all!” 

“And just what is this?” he said as he walked fearfully over the shattered remains of the front door to his smithy and peered inside in amazement at the stack of smoking-hot, sparkling spearheads left behind by the ogre. Indeed, it turned out the red ogre had left behind exactly 999 completed spearheads, each wonderfully made.

From that day forward the blacksmith’s shop was famous for the quality of its spearheads, which are still known as “ogre-spears.”

And the blacksmith became wealthier than ever.

The End

Even ogres need love

The Japanese Gennou & Handle Part 15 – The Drawing Part 4/6

Statue of Filippo Brunelleschi, the father of technical drawing and linear perspective, and both architect and builder of one of the largest and most magnificent domes in the world. Thanks, Maestro Brunelleschi, for teaching us how to draw! But what’s up with pokin holes in pizza dough…?

One accurate measurement is worth a thousand expert opinions.

Grace Hopper

As your humble servant mentioned in a previous post, and contrary to what corporate product development departments appear to assume, it is the nature of the human body for the hand to precede the hammer head during the arc of travel, with the result that, if the handle is affixed perpendicular to the axis of the head, the hammer’s face will hit the nail or chisel handle off-center and at an angle. 

In this post we will discuss this eccentric phenomenon in more detail and suggest how to compensate for it in Gentle Reader’s drawing.

The Angle of the Dangle

In evidence of your humble servant’s counter-intuitive assertions above, let us view some stop-motion high-speed photography of a shockingly ugly hammer (‘Nando is simply clucking with disapproval at the sight). 

Although the wood-butcher in this photo is using the inefficent Hobbit-basher grip, please notice the location of his pinkie finger with respect to the hammer’s face shown in this photo, as well as the angle between the hammer’s face and the nail’s axis at the point of impact seen in the last frame.

Now riddle me this, Oh Enigmatic Sphinx:

  1. In this series of photos did the impact between hammer face and nail head occur in the center of the claw hammer’s face, or in the lower half of the face?
  2. Was the center of mass of the hammer head in-line with the axis of the nail at the instant of impact, or was it offset?
  3. Was the striking face oriented perpendicular to the axis of the nail at the instant of impact, or cocked?

Gentle Readers who answer all three questions correctly will win one-half of a day-old Crispy Creme glazed donut the next time they are in Tokyo (I get the first bite of course (ツ)). But rather than just giving out the correct answers (and risk losing half a donut!), Gentle Readers should perform the following tests themselves to gain irrefutable personal knowledge.

The Experiment & Analysis of the Results

Color the face of your hammer or gennou with a marking pen, or Dykem, then use it with a chisel to cut a mortise, without giving the hammer special attention. Perhaps a dozen blows to the chisel while it is held vertical. Then examine the hammer’s striking face and chisel handle.

Now that’s done, please examine the chisel handle. What Rosetta Stone should we use to decipher these mysterious marks?

If the ink has transferred from the hammer face to the chisel mostly dead-center, then all is well. But if it is off-center, it usually indicates two things. First, the hammer handle is either too long, too short, or your grip is goofy. Second, it may indicate that the hammer’s head is cocked at the instant of impact. More on that next. In any case, a clean impact on the end of the chisel must be our goal if we are to work efficiently (A little nod to the gods, for we are fallible, and perfection is unattainable). Therefore an adjustment to either the hammer, or the way we grip it may be called for.

Let’s take a gander at the hammer’s face next. Most people discover that the ink has been scrubbed off the bottom half of the hammer’s or gennou’s face (closest to the hand), and that the ink marks transferred to the chisel are off-center. 

If the bare spots (where the ink was scrubbed off) are not centered on the hammer’s striking face, two things are indicated: First, as seen in the photo above, the hammer’s face is probably not striking the chisel’s handle squarely, but is angled at the time of impact instead of being perpendicular. Not good.

The Consequences

Why should we be concerned about something as insignificant as an angled impact? How clever of you to ask such a intelligent question! Vector analysis suggests that an angled impact must cause the hammer to push the chisel away from the intended direction of cut, or the nail away from the intended goal (maybe even bending it). This has consequences we need to be concerned about.

The second thing these uneven marks indicate is more certain, namely that the centerline of the hammer’s head is not in-line with the centerline of the chisel’s handle at the time of impact. Once again, physics and vector analysis tells us this misalignment causes impact energy to be misdirected and wasted instead of being transmitted through the chisel to its cutting edge and into the wood being cut. The resulting feeling is a whack followed by a kick instead of a clean chopping sensation. 

Where does this wasted energy go and what does it do? It forces the chisel out of the ideal alignment and makes it feel squirrely. It beats on the hand holding the chisel. It also converts to friction heat as the blade beats on the wood instead of cutting it cleanly.

This wasted energy destroys your hammering rhythm, dulls your chisels, hurts your hand, bends your nails and makes your chisel-work sloppy. This condition can no more be tolerated than a rabid gerbil or a corrupt politician. Or is that a rabid politician and a corrupt gerbil? I forget, but it’s a difference without a distinction.

In any case, if we want the hammer’s energy to enter the chisel cleanly and motivate it to cut both efficiently and precisely, we need the center of mass of the head to be oriented closely in-line with the central axis of the chisel or nail at the instant of impact. Likewise, we need the gennou’s flat striking face to impact the chisel handle or nail head squarely, not at an angle.


Your work with a hammer will be most efficient and precise if you meet the following three conditions:

  1. Grip the hammer’s handle correctly;
  2. Use a hammer with a handle length that fits your body best;
  3. Use a hammer with head alignment and striking face angle that corrects the misalignment and cocking inherent in standard hammers as mentioned above.

The following guidelines should get your handle design in the ballpark.

When gripping the hammer as described in Post 13 in this series, your pinkie should just fit between the front edge of the handle and the plane of the flat striking face. The small circle drawn near the end of the hammer in the drawing is the pinkie, a dimensions that varies from person to person.

This means that if you place the gennou on a flat tabletop as shown in the drawing, and press straight down on the head so the flat striking face is flush with the tabletop, the toe of the handle will float above the tabletop with just enough clearance for your pinkie to fit between handle and table when you grip it properly.

So let’s take some more measurements and add them to our drawing.

Grip Layout

First, measure the diameter of your pinkie. Approximate is fine.

Next, we need to determine where to draw the pinkie in cross section on our drawing, but to do that we first need to measure the size of your grip. To do this, hold a hammer handle or stick in your hand gripping it lightly across your palm as described in the previous post in this series (not in a Hobbit-basher fist) with the heel of your palm and the first segment of your index finger resting on the handle’s back edge (opposite the head’s striking face), and your fingers wrapped around the handle. Use a pencil or pen to following mark 3 points on the handle or stick:

  1. Make the first mark at the point where your palm’s heel ends on the handle’s back edge near the butt. Let’s call this Point 1;
  2. Make another mark at the point where the first joint of your index finger begins to curve around the handle/ Let’s call this Point 2;
  3. Make the third mark where the front and back edges of your pinkie finger touche the handle’s front edge. We’ll call this distance your “pinkie diameter.”

The length of the “grip” is the distance from Point 1 to Point 2.

Going back to our drawing, layout the “grip” length or “forefinger” location as shown in the drawing.

A line drawn from the top of the butt to the intersection of the grip length, as shown by the arc in the drawing below, will give you the grip angle.

Next use your divider to transfer the location and width of your pinkie finger onto the bottom edge of the drawing’s handle touching the horizontal line. Sketch a circle representing your pinkie finger in cross-section.

With the addition of these details to your drawing, it is close to being complete. I’m excited as a puppy on Christmas morning!

In the next post in this saga spanning time and the islands of the seas we will add the handle’s top and bottom edges.

Japanese Saws: The Ryouba

If you can’t stay young, you can at least stay immature.

Red Green

The Ryoba saw is certainly the best-known woodworking saw in Japan if only because of its unique shape. Indeed, for as long as your humble servant has been making a damned nuisance of himself on the earth, it has been the single tool that most represents the Japanese carpenter in the public mind. It is probably the best-known Japanese saw outside of Japan too, second only to the Dozuki saw.

In this post we will discuss the Ryouba saw in general, and the Ryouba we provide to our Beloved Customers in particular.


The full name of this saw is “Ryouba Nokogiri” written 両刃鋸 in Chinese characters, and pronounced “ryoh-/bah/noh/koh/giri.” Ryou means “both,” “Ha” means “blade” or “cutting edge,” and “nokogiri” means “saw.” In other words, a “double-edged saw.”

The word is almost always spelled “Ryoba” in the English-language alphabet, but the “o” in “Ryo,” in this case, is actually pronounced a little longer. When I was young man first learning the Japanese language on Shikoku Island, the convention was to express this longer pronunciation by adding a straight line over the letter “o” to look like “ō”, but with the wide use of computers nowadays, the trend seems to have shifted to adding a “u” after the “o,” which is perfectly consistent with how it’s written phonetically in Japanese (りょうば ). But I digress.


Being double-edged, the Ryoba has a set of progressive rip teeth (becoming gradually larger towards the tip) on one edge and cross-cut teeth on the other. It is a relatively recent invention, first appearing around 1897, instantly gaining tremendous popularity throughout Japan.

While the invention of cross-cut teeth is at least several hundred years old, archaeologists and researchers have postulated that they are a recent development, at least in Japan.

Why a Double-Edged Saw?

Because the Ryouba saw combines both a rip-saw and crosscut saw into a single saw, it has the following advantages over single-edge saws:

  1. More efficient use of expensive steel and labor than a two-saw set comprised of a single-edged crosscut saw and single-edged rip saw;
  2. Reduced weight and space requirements, especially important before people generally had automobiles to help carry the load;
  3. Fewer saws to keep track of, and less time spent switching between them.

But all is not blue bunnies and fairy farts because, compared to the single-edged saw, the Ryoba saw has a few disadvantages Gentle Readers should be aware of:

  1. While the blade of a single-edge saw (kataba nokogiri 方刃鋸) is thickest at the teeth, and tapers thinner towards the back of the blade to reduce friction in the cut and to prevent the blade from binding, the Ryouba saw is thickest at both cutting edges and thinnest at the centerline of the plate between the teeth. The result is that, if one makes a cut using a Ryouba saw in a timber or board deeper than the thin centerline of the plate, friction in the saw kerf acting on the blade will increase as the cut approaches the offside teeth. The result is that the Ryouba saw is not ideal for deep cuts;
  2. If one uses a Ryouba saw to cut into a board or timber deep enough that the teeth from the opposite edge fall into the saw kerf, the opposing teeth will tend to score the surface of the wood surfaces inside the kerf. While these scratches may be of no consequence for many types of cuts, the Ryouba saw is still not ideal for some types of cuts.

The Ryouba saw is perfect for many other applications, however, especially when working in the field.

When doing cabinet or joinery installations I always have a Ryouba saw on-hand simply because a single saw that can make shallow rip cuts and crosscuts is simply more time and cost efficient. The one in the photos below is my favorite.

Fine-toothed Ryouba saws like the one above were once common but are difficult to find nowadays.

The C&S Tool’s Seigoro Brand Ryouba Saw 清五郎印両刃鋸

We carry two ryouba saws, a 270mm (teeth length = 255mm) and 240mm (teeth length = 230mm). The longer of the two is well-suited for general carpentry, while the 240mm is better suited to finer work.

C&S Tool’s Seigoro brand 230mm Ryouba saw

Our Seigoro brand saws were made by Azuma Kenichi 東賢一, the third generation Nakaya Choujiro in Nagaoka City Japan.

I have been using Choujiro brand saws made by Mr. Azuma’s father and grandfather for many years and have been absolutely satisfied with their quality and performance. We are thrilled to be able to offer a limited number of his Ryouba saws to our Beloved Customers.

These saws were a special order Choujiro filled using the last of his stock of Shirogami No.2 steel some years ago. We purchased the remainder of this order from the wholesaler who originally ordered them. There will be no more.

Choujiro no longer makes saws this large, having since shifted his focus to smaller saws used by European luthiers and model makers.

Of course, used Ryouba saws are available on the auction sites. The problem with used Japanese saws, however, is that it is impossible to judge the quality and preservation of a saw from photos alone. The only way to tell if a sawblade is kinked, warped, or oil-canned is to hold the saw up to the light, bend the blade, examine the reflections and feel the teeth. And the teeth of used saws are always dull and often damaged. Caveat emptor, baby.

These are new, high-quality saws made by a well-known blacksmith still working, perfect in every way, and backed by the C&S Tools warranty, so the risk of wasting money on an old saw you cannot examine in-person (assuming you have the expertise to examine Japanese saws to begin with), made by someone who’s name you cannot read, bought from someone that won’t give you back your money if the saw is not as good as it looks in the photos or even damaged before you receive it, is not a problem. (Wow, that was mouthful)

If a saw you purchased from us needs sharpening or repair, simply ship it back and we will arrange for a professional saw sharpener to restore its beautiful smile and revive its voracious appetite for sawdust, or even have Azuma-san repair it, if necessary, for a reasonable fee. Unlike thee and me, he doesn’t work for free. (Ah, poetry!)


The specifications of the saws are listed below.

  • Blade Steel: Hitachi Metal’s Yasuki Shirogami (White Label) No.2 (1.05~1.15% carbon content)
  • Tang Steel: SK No.5 (0.80-0.90% carbon content)
  • Tang/blade connection: TIG weld
  • Thickness/taper: Thinnest at blade centerline
  • Finish: Buffer
  • Tension: Hammer tensioned
  • Rip teeth: Standard (increase in size progressively from heel to toe)
  • Crosscut teeth: 3-facet “edome”

Saw Specifications

Ryouba saws are not specialist saws, but excellent general-use saws. If I could have only one saw in my workshop, or could take only one saw to a jobsite, it would be a Ryouba saw.

They are especially handy for general carpentry tasks and ideal for cutting tenons and many other joints in timber framing.

The Japanese Gennou & Handle Part 14 – The Drawing: Part 3/6

Top: A 100monme (375gm) gennou head by Hiroki mated to a new Osage Orange handle. Bottom: A 60monme (225gm) Kosaburo classic ryouguchi head joined to a mellowed Osage Orange handle. The difference in the size of the eyes and weights of the heads combine to make handles of different dimensions. Therefore the design begins with the head.

“This life’s hard, but it’s harder if you’re stupid.” 

George V. Higgins, The Friends of Eddie Coyle

In the previous post we started the drawing of our gennou handle using the gennou head as a template. In this post we will determine critical design details including the overall length, butt dimensions, and typical cross sections.

But first, since we are talking about making a tool we must grip in the hand, let’s consider how to hold it. You would be surprised at how many people get this simple action wrong. It matters in the context of this article because we are designing a minimalist tool for which the smallest details matter.

The Grip is the Grip

There are many ways to hold a gennou handle. The hobbit-basher grip in the fist is popular among many hammer wigglers, even those with five fingers, but it provides both low power and poor control, good for Bagginses but not so much for woodworkers.

The most efficient grip is to orient the handle diagonally across the open palm, touching the heel of the palm at one end and the pad at the base of the index finger at the other. The index finger and other fingers then wrap around and under the handle on one side, with the thumb gripping the opposite side of the handle so its is pinched between the index finger and thumb. This is similar to the grip recommended by the famous golfer Ben Hogan.

This method of holding the handle provides significant advantages:

  1. The wrist is able to rotate more freely and to a greater degree;
  2. The length of the hand touching and motivating the handle is much longer than the Hobbit-basher fist grip providing more leverage (couple) with less effort and more control;
  3. The touchpoints at the thumb, index finger, and heel of the palm triangulate the handle in the hand and mind so the user always knows exactly where the gennou’s face is located and its angle with respect to the target without looking at or fiddling with the gennou.
  4. The grip on the handle is more secure so the handle wiggles around less in the hand reducing blisters and stresses.

If you find this grip difficult, please stick with it until it becomes a good habit that displaces a bad habit.

Determine Overall Length

The next thing we need to add to our drawing begun in the previous post is the gennou’s overall length (OAL) measured from the handle’s butt (not including the dome) to the Vertical Centerline through the head’s face. This dimension comes from your body with some adjustment for how you grip and swing.

For most people, a good starting length can be measured by bending your hammer arm 90° at the elbow and laying a straightedge or folding ruler across your upward-facing palm and forearm. Touch one end of the straightedge against the tendon at your elbow and measure the distance to the base of your middle finger. In my case this 12 inches, but I’m not a big guy.

A classic Kosaburo gennou head mounted to a 12″ osage orange handle.

You may want to add an extra inch to your first handle. If you later decide the handle is too long, you can whittle it shorter.  Remember, the first handle you make will be experimental, and probably not a keeper. I suggest you plan on making at least three over a period of a few years and after sufficient testing to determine the ideal length for you.

As seen in the photo above, with the head held in a flat palm (not a fist), and the fingers wrapped over the head, the butt just touches my bicep tendon. In my case, by total coincidence, this is 12″. Add ¼” to the length for the domed butt; you will need it. At 5’8″ I am not a big man and have neither long arms nor big hands. Your handle may well be different.

Add this OAL dimension to your drawing.

Measure the Butt

So far we have focused on the head and overall length. The next details we need to determine are the dimensions of the butt, most importantly, its height.

The height of the butt is important not only because it determines how large the grip area’s circumference will be, but also because it partially controls the angle of the grip, and therefore the angle of the head and striking face at the time of impact.

Only you can decide what dimensions will work best for you, but since we need to start somewhere, I suggest you make the handle’s butt at least l” (25mm) wide (seen from above), and 1-⅜” (35mm) high. If you have large hands or prefer a large grip, or are using a heavier head, then the flat area should be wider to reduce pressure on the hand.

Reaction Forces

Next let’s consider the forces acting on the handle and the user’s hand, and their influence on the hammer’s performance and user’s comfort and endurance.

Commercial handles typically have a symmetrical oval cross-section that looks good, is easy to manufacture, and is consistent with the one-size-fits-nobody philosophy convenient for mass-production and mass-marketing. Sadly, this oval cross-section ignores the three reaction forces that act on the user’s hand. 

The first reaction force occurs when the user brings the hammer up in preparation for a strike. In this case, a force couple (matched forces) presses the handle into the first joints of the fingers and the heel of the hand (assuming, of course, one is gripping the handle as recommended above and not like a demented mountain troll).

The second reaction occurs when the hammer reaches the top of its swing and the user changes the direction of the hammer head towards nail or chisel. A force couple presses the handle against the first joint at the base of the user’s index finger, and the tips of the other fingers. The pinkie finger has a major role in retaining the user’s hold on the tool, you will notice.

The third reaction occurs when the speeding hammer head impacts nail or chisel and the handle kicks back at the user’s palm and fingers, just as Sir Isaac Newton predicted.  

If these reactions are balanced to the object being struck/cut by the weight and speed of the hammer, this cycle can be smooth and efficient and the kickback forces minimal. But if the hammer is too heavy, or too light, the forces the user must apply to the hammer and the force and pressure of the resulting reactions can be become tiring and even bruising. A good handle made to fit the head and the user’s body and hammering technique will improve efficiency and reduce wear and tear on the user’s body.

What is this wear and tear you say? All the aforementioned reaction forces cause the handle to kick the muscles, tendons and bones in the user’s hand, and can cause bruising. Even if it doesn’t bruise, after a long day of chiseling the hand wielding the hammer will be more worn and tender than when the day started.

Even if you never grow tired and pain means nothing to you, Oh Master Blaster, these reaction forces tend to push the handle out of alignment in the user’s hand shifting the next hammer stroke slightly off-line, and twisting the hammer’s face slightly out of ideal alignment. Have you ever noticed how the hammer becomes wobbly after a couple of blows in quick succession? Guess why that happened.

Back-edge/Top Cross-section: Flat

In the case of this Yamakichi gennou by Hiroki, the striking face is is towards the right side of the photo. Please notice the shape of the handle with respect to the striking face.

The solution to these troublesome physics problems is simply to make the top/back edge of the hammer in the grip area more-or-less flat instead of round or oval, a modification that will spread the reaction forces more evenly across your hand, preventing bruising and reducing fatigue. It will also stabilize the handle in your hand improving unconscious alignment and reducing twisting.

You have probably never seen a handle shaped like this much less used one. It may look uncomfortable in your mind’s eye or on paper, but it is comfortable in-use. Try it before you dismiss it.

Another big advantage of the flat on a hammer handle is one you have probably never thought about, but the lack of which has wasted much of your time while using hammers. When doing woodworking especially, we tend to set our hammers down while we change position, move the workpiece, or remove chips. Often, we don’t recall the angle or direction we set the hammer down, so when we pick it back up we must double check two things by eye: First, where our hand is located on the grip, which distance of course determines how far the center of the striking face is from our hand; and second which face/ claw of the hammer is facing which direction.

I don’t know about you, but I want my hand to learn this information and get the hammer oriented properly without my having to take my eyes or attention away from the work at hand. Anything else is stupid.

The flat immediately tells your hand which direction the striking face is oriented, and where your hand is located on the handle, all without using your eyes or giving the matter a single thought. It’s a psychic handle, sorta (ツ)

Front-edge Cross-sectional Shape

While the top/back of the handle is more or less flat, as seen in the photo above, the lower/leading edge (surface facing the chisel or nail) should be circular at the butt, gradually transitioning to a flat surface as it nears the eye. Some people like this surface to be egg-shaped. I prefer a simple circular radius. For your first gennou handle, I recommend you begin by making it a simple circular radius and shave and whittle it to fit your hand more precisely later.

The reasons for making this surface rounded are simply to maximize the surface area of contact between hand and handle, and to make the grip comfortable.

Put all this into a simple sketch and transfer it to the drawing. At this point the end view of the butt should be shaped like a pregnant letter  “D” with the curved surface oriented downwards towards the bottom of the page of the profile drawing.

Side Surface Cross Section: Flat and Parallel

So far, we have determined the back/top edge will be mostly-sorta-kinda flat, and the front edge will be more-or-less rounded. Next, let’s examine the two side surfaces.

Looking at the butt in cross-section, the handle’s right and left sides should be perpendicular to the flat on the handle’s back/top edge (plan view). These curved-plane surfaces begin at the head’s eyes, and curve down the handle all the way to the butt with some radiusing and softening of course.

Please note that, unlike commercial wooden hammer and axe handles that need a goofy flair below the eye to keep steel wedges from splitting the poorly-made handle, this minimalist gennou handle does not. It is an elegant, handmade craftsman’s tool, not a nail-bender or cockroach killer, and simply doesn’t need wedges.

Instead of a cancerous bulge, the handle remains a few shavings thicker than the eye for some distance until it smoothly flairs into the grip area. This design has serious advantages we have discussed in earlier posts in another series about what hammers to use with chisels, which I will briefly summarize.

  1. A minimalist, thin handle has less air resistance wasting less energy, a serious concern in a tool moved as quickly as a gennou;
  2. A thin handle transits fewer shocks and vibrations to the user’s hand;
  3. A thin handle is easier to pinch between index finger and thumb providing maximum control in the Ben Hogan golf club grip;
  4. If and when the handles loosens (it’s only wood after all, not eternal Chinese-made plastic-covered bent sheet metal), the user can tap the handle further into the eye quickly tightening the handle without pausing work. Note that this is not necessarily the ideal permanent fix, although it certainly can be.

Some will look at the thin handle and fear it will break. This is always a possibility with any wooden handle, but your humble servant has never broken a properly-made gennou handle, although I have broken plenty of commercial hammer handles. The key is to make your handle from the right wood, with proper grain orientation and minimal runout (we’ll talk more about these details in future posts), and to always use the head, not the handle, to drive nails and wack chisels. Duh.

We will talk about these specifications and details in future posts in this story of crime and passion.

In the next post we will determine the angle between the head and the handle. If you think this angle is unimportant then you’re in for a big surprise.

Tenant Improvement Work in Japan – Part 1: A Work, B Work, C Work

Charles Fletcher Lummis

This article is not focused directly on woodworking or woodworking tools per se, but rather on how to go about leasing space in Japan, and contracting for construction in that space. The wood and tools come afterwards.

I have never seen the subject of Tenant Improvements (or Tenant Fit-out, as it is called in some countries) addressed in writing outside of real estate dealings and construction projects in Japan, and never on the internet. It will no doubt sound like gibberish to many, but those involved in the real estate or commercial construction industries may find it interesting and maybe even profitable.

You should find it especially interesting if you anticipate leasing space in a building in Japan, or doing construction work in a leased space here. This little bit of basic insider knowledge could make you look like a genius.

You Don’t Know What You Don’t Know

Too often I have worked with people and companies, who shall remain nameless, that made planning decisions without the insight described below. The results were sometimes painful.

The most jarring incidents I have seen occurred with people and companies accustomed to real estate leasing and construction projects in their own countries, but who are willfully ignorant of how things are done here in Japan, and insist that the knowledge and experience they possess is applicable without significant adaptation. In response to corporate pressure, and based on a poor understanding of local realities, these lost souls plan the process to fit their abilities confident they will be able to manipulate the Landlord and contractors through a combination of their devastating charm, superhuman negotiation skills, and the leverage afforded by their company’s wealth and fame. In a leasing market of 96% occupancy, such people frequently wake up to find reality kneeling on their neck while carving tasteless limericks into their forehead.

The most pitiful prospective tenants I have seen came to Tokyo from Hong Kong and Singapore. They sent younger employees to handle the leasing, always with good English-language abilities, but no experience outside their own country or mainland China, where they had only dealt with unsophisticated and hungry brokers, consultants, and contractors to whom they could dictate terms and conditions. Absolutely convinced the Hong Kong or Singapore way of doing things is the only way, they waste time, money and goodwill banging their heads against a stone wall never realizing that Japan has an advanced real estate and construction industry with many companies hundreds of years old and possessing technical capabilities few, if any, American or European companies can even think to match.

Delays, budget overruns, embarrassment, pattern baldness, and sudden employment changes ensue.

I prefer to avoid all that drama. How about you?

The Tokyo Office Leasing Market

A commercial office building under construction. The completed building is of exceptionally high quality.

High unit lease rates and the tricks of the trade described below have made owning and leasing out office/retail space in a Class 1 office building in Tokyo one of the world’s most profitable, risk-free, and steady investments.

You won’t see this fact written about in financial publications, however, because it’s small club that’s difficult to join and with few opportunities for foreign financial consultants to make a profit in the fly’s lifespan time-window they allow for investments to bear fruit. But there are a few savvy real estate investors outside of Japan who know the value of owning the right building in the right place in a Japanese metropolitan area and wish they could get a piece of it.

A handful of foreign companies and investors have succeeded here, especially in the hospitality industry, but it is a long row that few non-Japanese companies have the patience or connections to successfully hoe.

All of the terms mentioned in this post are related to a tenant space (usually office or retail) leased in buildings in one of Japan’s major cities, and constructing the improvements (aka “tenant improvements,” “TI’s,” or “tenant fit-out”) needed to make the space usable.

So let’s dive in and paddle like a duck in an alligator farm.

A Work

No alt text provided for this image
A jobsite in Tokyo with extensive drilled-piling work underway. 12 cranes and 6 drill rigs are working concurrently. 600 trucks entered and left the jobsite daily during this foundation work.

“A Work” (short for “Category A Work”) is a contractual term in Japan which refers to construction work performed directly on the “Base Building” on behalf of a Tenant in the building. This type of construction work does not, however, come into play until the building’s construction is complete and the terms of a tenant lease agreement are being negotiated.

“A Work” typically includes any modifications to the base building’s structure, core & shell, mechanical, electrical and plumbing systems, elevators, common areas, etc. If you need to cut holes in the floor slabs for stairs between multiple floors you will lease, or need to add duct space or pipe shafts for your rooftop equipment for instance, it will be A Work.

Owners of high-quality buildings in metropolitan areas are understandably keen to preserve their investment and the income it produces and so will always have their designated contractor perform A Work at their direction but at the Tenant’s expense. This is an important point to keep in mind.

You will have no opportunity to competitively bid A Work, so save yourself the embarrassment of insisting, being rebuffed, and having to explain a strategic error to your board of directors.

Be aware that if you intend to propose to the building Owner or Landlord that the modifications you require will improve or upgrade the base building, and therefore the cost should either be borne or supplemented by them, you will need to conclude those negotiations before you sign the lease, while you have leverage, or the entire cost will be your responsibility.

Please note that it will be your contractual obligation to pay for restoring the building to its original condition, whether the Owner/Landlord actually does it or not, and even if that means downgrading the building. The cost, for instance, of removing/restoring a stairway between floors frequently costs more than the original construction itself. Ouch is right.

We will discuss “Restoration” in a future post in this series.

B Work

No alt text provided for this image
Electrical work underway.

“B Work” is another contractual term you will need to understand. It refers to tenant improvements (aka “tenant fit-out”) “connected” to the base building.

B Work typically includes all mechanical, electrical, lighting, plumbing, HVAC, ductwork, fire life-safety work (fire sprinklers, gas fire suppression systems, fire alarms and emergency lighting, etc), partitions, ceilings, OA floors (raised floors) wall finishes, most floor finishes, blinds and PA systems to be constructed or installed inside the lease space, as well as Tenant-requested BMS systems, emergency generators, chillers and heat exchangers required to service the tenant’s equipment.

Often millwork (cabinets), kitchen, pantries, and sometimes even system furniture to be located within the tenant’s leased space are included in B Work too. The old, bitter joke is that if you turn the building upside down and shake it, everything that doesn’t fall off is either A or B Work. Not a lot left.

B Work too is almost always performed by the Owner/Landlord’s designated contractor(s), often the same ones that constructed the building originally, at highly inflated prices. You won’t see it as line item in the B Work contractor’s cost estimate, but the Owner’s and management company’s hefty cuts are included.

Here is a critical point to grasp: Competitive bidding is not an option for B Work. Your company’s strict procurement rules will therefore be irrelevant, so best to get your procurement department on-board early. But don’t worry, this isn’t the only standard “carved-in-stone” rule your company will need to adapt.

The Tenant normally signs a construction contract directly with the designated B Work contractor(s) but has very little leverage to control construction costs. The Owner/Landlord has no motivation to see these construction costs reduced, you see, and so will not aid you in reducing them. Do you see where this is going?

C Work

No alt text provided for this image

The third type of Work we will discuss in this article is called “C Work.” It includes everything the Tenant wants constructed besides A Work and B Work, including carpet tiles, Audio-visual equipment, IT cabling and servers, Telecom, UPS, security systems (card readers, security sensors and cameras inside tenant spaces) millwork (sometimes), specialty lighting and sound systems, AV systems, and loose furniture. Usually system furniture too, but not always.

Sometimes C Work includes interior partitions, such as glass or metal partitions, that are installed between the OA floor and the ceiling and do not connect directly with the floor slab or overhead structure. This item is often a good opportunity to save costs and is worth negotiating thoroughly before signing any lease. More on this in the “Demarcation Table” section below.

Unlike A and B Work, a Tenant can directly perform C Work using qualified licensed contractors they select. Bidding is entirely possible and construction costs are typically at market prices much less than A Work and B Work, so compared to A Work and B Work, cost savings can be realized.

On the other hand, if you are in a dreadful hurry and/or can’t be bothered to deal with producing drawings and hiring contractors, then asking the B Work contractor to execute your C Work design/build is an excellent, but expensive way to simplify and expedite the process.

You will want to prepare well and plan your lease negotiation schedule to take advantage of the local knowledge your PM team possesses to move as much of A Work and B Work into the C Work column of the Demarcation Table as possible.

The Demarcation Table

No alt text provided for this image

As you probably deduced from my vague definitions of A, B and C Work above, the limits of each type of construction work vary from city to city, landlord to landlord, and from building to building. Sometimes they are negotiable, sometimes not.

The “Demarcation Table,” or more correctly “Construction Work Demarcation Table” 工事区分表 is a document that becomes part of the lease agreement and lists the items of construction work included in A, B, and C Work. As the Tenant, you or your agent must negotiate this document along with the lease.

Careless people sometimes leave this discussion for after the lease agreement, but a wise Tenant will know before beginning negotiations what construction work they will need, what concessions they want, and the likely unit prices they will be charged for construction so that negotiations will go smoothly, the best deal can be obtained, and buyer’s remorse can be avoided.

Having a knowledgeable leasing agent and Project Management team on your side during this critical process will make the process quicker and the results more economical.

Allow me to share a few examples of how to handle the Demarcation Table to your benefit during Lease Agreement negotiations.

For instance, the Landlord may not be willing to discount your lease as much as you like, but if you are prepared in-advance, you may be able to convince him to tweak the demarcation table so some expensive construction items, and/or items you want your contractor to perform, are shifted from B Work to C Work allowing you more control at less cost.

Or perhaps you need to install a backup generator to service your IT system. You will need space to install it, and provisions for a fuel tank, fuel lines, and exhaust and cable shafts/ducts. If you negotiate carefully and early, you may be able to get the space for free, or at a discount. After the lease is signed, however, fat chance.

After they perform their electrical load calculations, some tenants are surprised to learn that, while the building overall has adequate power for their needs as confirmed during due diligence, they will need to install a transformer or three to step the power up or down or change the phasing to meet their power requirements. Labs, cleanrooms, kitchens, and video studios, for example, use a lot of juice.

Transformers often must be mounted outside, perhaps on a balcony or more likely on the building’s roof. Transformers, switchgear and electrical panels are definitely “long-lead items” that take months to fabricate/procure, as are the steel electrical cabinets to house them. If you know you will need this equipment you can adjust your schedule and budget early, and negotiate concessions from the landlord for space, and access. But if you wait until the lease is already signed, your leverage will be gone, baby, gone.

Why does all this matter, you ask? It matters because once you sign the lease, you are committed and have no choice but to pay whatever price the Landlord and his contractor want to charge you for A Work and B Work, and comply with their schedule. There are ways to minimize the pain, but on your own you won’t have the relationships, the data, the local experience, or the language skills to make meaningful headway. Conversely, you most definitely will have the ability to increase the costs of A Work and B Work by creating hard feelings with the Landlord through confrontational Trumpian-style negotiation techniques.

Don’t push or allow your real estate leasing representative to negotiate your lease in a rude, condescending, or pushy manner because, if he does, the Landlord will make you pay for it ten times over later in cashy money.

There are many other details related to A work, B Work and C Work you need to identify through due diligence, engineering consultation, cost estimating, scheduling and negotiations. Experience in the locale and possessing good relations with the Landlord, contractors and consultants are critical. You will need a good Project Manager with local experience to ensure this work gets done quickly and completely, unless, that is, you enjoy explaining budget overruns, schedule delays, and inadequate facilities to your boss or board of directors.

Building Permits

In many countries, the process of obtaining building permits/approvals is a huge uncertainty, and sometimes a crap-shoot that delays schedules and wastes huge amounts of time and money. In Japan’s metropolitan areas, however, building permits are typically not required for tenant inprovements. There typically aren’t even any inspections by the building department.

The one sure exception to this general rule is the Fire Department, who will need to review the fire sprinkler and other fire/life-safety drawings the B Work contractor will prepare and submit to the Fire Department. The Fire Department will also insist on inspecting the building at the completion of construction, but before occupation. This is a “hard stop” to construction that cannot be avoided, and sometimes consumes a week or more. Careful preparation by a respected B Work contractor can accelerate this process.

As the Tenant, you have no role in this process other than to stay out of the way.

If your legal beagles get their panties in a knot out of concern about potential non-compliance of the Work with local codes and regulations, tell them to take a handful of Xanax with a cold brew and just chill because the general contractor has full legal responsibility for defective and/or non-compliant work. I have never seen permits or approvals become a problem.

You would be wise, however, to have your Project Management team in Japan perform regular inspections and report to you until the construction is complete and the project receives occupancy permission from the Fire Department.

In the next post in this series we will examine the design process for a tenant fit-out project in Japan.
