Thread: Japanese Whetstone Polishing Powder

Reading the label it looks like it is a mixture of powdered Aiwatani and Shobudani hones. Sort of prefab slurry. Hopefully the dust particles aren't too coarse as to damage the cutting edge. Please let us know how you get on with this powder.

About This Item

Mined from Natural Japanese Whetstone, this powder is used for polishing Japanese traditional kitchen knives ( Wa Bocho ) and woodworking tools and is capable of achieving a 'Kasumi Finish'

These natural Whetstone powders are the one produced when cutting the stones at the workplace of our supplier. Then they had it crushed even finer. We prepared 100g pack in each.

I’ll def keep y’all posted. I seen the stuff on the site and was just curious if anyone here had used it, and if so how. I have a smaller squirt / dropper bottle. I’m gonna try it that way and just adding powder in the stone with water. It appears and feels extremely fine, I didn’t feel any sharp pieces. I know that doesn’t mean there may not be any, but it felt like baby powder.

If it's for kasumi it'll be hit n miss whether it works for your intended purpose. Suck it and see as we say down here.
