Thread: Japanese whetstone sharpening stone #15000 grit / resinoid metalmaster stone

I've tried it. It's maybe an 8K, certainly not a 15K. There might be 15K regions in the thing, but there are also a lot of giant particles which seem to have been added for cosmetic reasons. I wasn't able to determine if the purple bits or the greenish blobs were responsible, but it doesn't matter. The deep gouges this stone leaves in your bevel are visible without magnification. Not a desirable result from a finisher.

I dubbed this thing a "Hone Shaped Object" and tossed it in a junk box in case I ever need a gift to give to an enemy.
