Thread: Sharpening/Polishing Stone Grits

I apologize in advance if this has not been covered in some other forum. I have been reading some of the links asking if someone should use this or that stone and I'm not sure if some realize that there are differences in how "grits" are measured. I only have experiences with Japanese wet-stones (other than a couple diamond stones for kitchen knives) and a couple of Shapton stones. This link ) is one that I found years ago when I began to find interest on polishing Japanese swords: [FONT=Garamond][SIZE=1][COLOR=Black][FONT=&quot] www.nihonzashi.com

I'm relatively new to SR shaving (3-4 months), but puting a keen edge on blade is an old hat. The key is not taking too much material away & removing the scratches from the previous stone. I can't believe that it took me so long to give SR shaving a try. I'm hooked.
