Sharpening Part 27 – The Entire Face

A beautiful face: Oohirayama Lotus stone

If a dog will not come to you after having looked you in the face, you should go home and examine your conscience.
Woodrow Wilson

The subject of how to use the face of your sharpening stone is so basic and seems so unimportant that few give it the attention it warrants. But it is not trivial: it deserves its own post because it can truly make a big difference in the time and money you spend sharpening.

Money Down the Drain

Instead of focusing his attention on the blade alone, a wise man will make a conscious effort to use the entire face of his sharpening stone from edge to edge, end to end, and corner to corner instead of digging an oval swamp in the center of it’s poor abused face.

This habit will help to keep a stone’s faces flatter over more strokes longer, saving time truing the stone, and extending its life thereby saving money.

Remember that you paid money for the stone, the entire stone, not just the hollowed-out oval area in the center most people create when carelessly sharpening. How much of a stone do most people throw away? Idunno,… 20% maybe? Assuming this approximation is correct, just for the sake of illustrating a point, if you paid $100 dollars for the stone, that means $20 was turned into mud and washed away without providing Beloved Customer any benefit at all. And don’t forget the time you spent cutting down those high spots to keep the stone’s face flat. That makes it more than a $20 loss if you count your time worth anything, which you should.

Why not use the sides, ends and corners of the stone’s face too?

Developing Good Habits

When developing these intelligent work habits, it helps to cross-hatch the stone’s surface with a carpenter’s pencil to help you keep track of the areas you have not yet touched. Never fear, for while industrial diamonds are made from graphite, the form of graphite in pencil lead is still softer than the finest sharpening stone and won’t affect the sharpening process a bit.

Also, before and while sharpening, frequently use a thin stainless steel ruler to check the stone’s face lengthwise and crosswise at various locations, and of course on the diagonals to monitor wear. Don’t guess, lazy bones, examine. Between ruler and pencil you may discover you have developed less-than-efficient sharpening habits. With some thought you will also figure out how to change those habits so your sharpening efforts will be quicker and more cost-effective.

Before long, you will be able to detect uneven wear and warpage fairly reliably without using either tool as much, so stick with it until you do.

Hang Ten

One conundrum you have probably already discovered is that it is impractical to use the extreme right and left sides and both ends of the stone’s face to sharpen a blade. Or is it?

Here is wisdom: Teach yourself how to sharpen a blade’s bevel with one corner of the blade hanging off the stone part of the time, alternating evenly and frequently between right and left corners, of course. Strange as it may seem this technique is effective at not only keeping your sharpening stone flatter and making it last longer, but for keeping the cutting edges of your blades straighter. If this doesn’t make sense to you, think about it real hard. Then give it a try and you will see what I mean.

And since you are taking short strokes anyway, why not work the blade crosswise at the ends of the stone? A lot of expensive stone going to waste there, I’d wager.

I hate to sound like a broken record, but you will find that making short strokes will make it much easier to use the entire face of the stone.

If you feel this post needlessly states the obvious, or is “verbose,” allow me to remind Gentle Reader once again that the purpose of this blog is not to provide entertainment, sell stuff, troll for clicks or to trip and roll subscribers into Google Analytics’ s*thole, but to help our Beloved Customers develop good work habits through education. Some of them are newbies, and others are old hands, but if I were to write only for the professionals then I would be neglecting the newbies, so if you know this stuff already please congratulate yourself and celebrate your good fortune by buying a new carpenter’s pencil.
