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.
