I really don't know if what I have is considered a full set or not. What I have is 1K-3/8K-12K naniwa and a 20K. Also a 4/8K Norton. I thought I was getting a good edge with the 12K as a finisher but this 20K takes the edge to a whole new level. What i'm wondering is should you use the paste after the 20K or just strop it. anyone out there try it. would there be any advantages. any thoughts on the subject.
