Thanked: 2204I am referring to the size of the abrasive grain. A few years ago when the Chinese 12K became available one of the members of the SRP posted a link to a Chinese website that showed the Chinese standard of grit measurements. When broken down by micron size the Chinese 12k was comparable to the US CAMI/ANSI standard, the Japanese standard ( sorry, forgot the name) and the European FEPA standard at approx 10K.
I agree with you regarding the Chinese 12k seeming to be a finer stone than the coticule. But what I am interested in is the both the texture and sharpness of the edge. I try to find what agrees with my face the most, not just sharpness.Randolph Tuttle, a SRP Mentor for residents of Minnesota & western Wisconsin
