I was finally able, after about 3 tries and a little cursing, to get an edge that would whittle beard hair (I know its thicker, but its the best I can do now) off a 200 grit green water stone. The knife is an old Scout Lite that I reground to thin the edge. It uses Buck's older 425 Modified steel. Shaves hair off my arm and whittles coarse hair, just barely. I took it all the way to 0.3 micron honing film after testing the coarse edge, so if I want to do it again, I have to start over. Next is hair shaving with a filed edge. Dont wait for a post, this may take a while.
