I was wondering what kind of edge 52100 likes. I've only been making knives for about a year and have had pretty good luck with O1 and 1095. D2 was a problem, but I've been playing with 52100 and love it. It somehow seems to slice through meat and veggies with ease even after the knife appears to have lost its initial edge. I've been sharpening to 600 grit, then taking it to a leather strop. How does everyone else treat their 52100, coarse or fine edge?
