Thread: Chinese 12k Hone

It seems to polish a razor fine, but you can feel the razor crossing over into the different layers as I do my X pattern.

At the risk of being a broken record, there is no such thing as a Chinese 12k nor 15k. As a natural stone, there is no appropriate grit rating associated with it. You've never heard of a 10k coticule or an 18k Escher. The reason for that is the same. A natural rock has no grit rating and it is inappropriate and deceptive for a vendor to attribute one to it.
