After reading about these stones...kind of like Japanese water stones but small....1/16-1/4" thick x 1/4-1" wide or so....I ordered a few and started stoning my folder blades. What a shock! These things work wonders. I began stoning a flat ground blade that I thought was very flatly gound, sanded to 400 and lookin good. Well...these stones told me the blade was not flat, had a few divots and bumps I was unable to see previously and after taking the blade to 900...it looks mahvelous. I have sanded my blades with sticks, metal rulers, pcs of blade steel, cork lined, rubber lined....all holding a pc of sandpaper trying to find the best deal. I use the Bose method of sanding a hollow ground blade on a smaller diameter wheel held stationary. They all work to an extent. But these stones really give you a quick, flawless surface. They are relatively cheap....from about $2 to $4 or so. You use them with a kerosene lubricant or some other. Try it....you might like it and it doesn't cost much to try. You can also gridn them very easily toi any shape. I gound one in a curve to stone the inside and beginning of a cut swedge. Perfecto!
 
I really like to use them near the plunge during hand sanding. They really seem to knock out those hard to reach scratches much easier than sand paper. You can also use them to sharpen. Some of the best pocket change I have spent.
 
Yep I love mine, I dont even use sanding sticks anymore.
These things rock.

Orange EDM stones, dig around and you will find the.
I use mineral spirits as a lubricant, you must use a lubricant when using stones such as this.

I looked around a bit, anybody have a suggestion as to the best place to get 'em? How many different grits are they available in?

.....EDIT: Nevermind I think I found the goods!:D
 
I use a lot of cheap waterstones for refinishing blades. They work quite well. I don't use them for the final finish, though.
 
mcmaster carr has good ones, too.
I was told to use them from a really talented friend, and MAN, WHAT AD IMMEDIETE IMPROVEMENT OVER PAPER.
