round rotating water stones

**Big Red** · 08-10-2008, 06:21 PM

all right guys, I have searched here as well as google and not found what I was curious about. ebverybody seems to hone by hand. however i saw in a magazine article years ago a japanese sword maker who used donut shaped stones to sharpen his swords. they rotated and water trickled out onto the stone as it spun. you just hold the blade at proper angle going across the stone.

does anybody haev any idea what I'm talking about? is my brain dead, was this obscure and that's why I find nothing on it? I seem to remember he went to 6000 grit but that the stones were available higher.

thanks.

I have seen a similar machine hone microtome blades at Leiden University when I was a medical student.

Moviemaniac has one. It's called a Shinko machine and here's his video:

The Japan Woodworker sells two honing machines. remember that making a sword is an entirely different process than razor maintenance .

I was in Sears the other day and noticed that they carry them:

The link says that this machine has a 1000 grit grinding wheel. Seems to me that it wouldn't be much use for razors without finer grits.

I saw one the other day at woodcraft that uses abrasive film on glass.

Makita and others make horizontal machines for sharpening planer knives.

I guess such machines are cool if they help you make a living

That seems like a lot of unnecessary work/equipment to get a razor touched up.

In all honestly, using a Coticule and a Nakayama, I can refresh a razor in about that much time. Besides, that machine inhibits the the direction in which the steels is abraded, edge leading on one side but trailing on the other. I don't see any advantages.

I suppose it works, so, to each his own, but I wouldn't buy one.

They sell the fancy machine in Germany, here.

DICK GmbH - Feine Werkzeuge zur Holzbearbeitung

You need to hit the British flag for English language and then click on tools at the top of the page and then click on sharpening tools on the left hand side of the page. Look down the page for the machine you have seen.

Goes up to 6000 grit, but I would have thought it was too gutsy for straights which like a light touch.

The grinders look a bit tasty as well.

Maybe better than elbow greece.

Happy hunting.

I wish there was a Dick Biz in my home town. I'd love to wander through there. They have lots of cool stuff.

I agree with Russ, it doesn't seem the the ideal razor thing.

Just for fun I'd like to see the tosho using that toy size grinder on a sword. The typical shop photos I've seen were always on a vertical wheel approx. 2' diameter, maybe 8 inch wide for removing clay coat and some initial shaping. But even in "traditional" work there are many ways and different approaches, opinions and evolving processes
