I've got myself a little stash of these guys and thought that maybe some of you might want some for yourself.
They're man made (no soak needed) stones that are sort of fast wearing yet fast cutting and they easily conform to shapes of uneven bevels and the popular hamaguriba form.
These stones aren't meant to re-surface the sides of knives like many people use natural fingerstones for. They're strictly for cleaning up and making an even surface appearance of the blade road of single bevel knives to bring up a nice kasumi finish and texture. The surface provided is great for food release and is easy on the eyes.
These little buggers are what I've been using for years to help me make not so pretty stuff look good. For a sharpener using synthetic stones on single bevel knives this is the answer you've been looking for.
I'm thinking of selling 3 or 4 pieces for $10. Any interest?
