I don't think they are full convex, I have a some older Blackjacks that are full convex and Hi kruks and they are very very sharp. So far, my CT and HR and the rest of the rats are fine for what they are intended for, my NO-E is asymetric and a class of its own. I would welcome some Limited version in zero edge, or asymetric instead. Any edge is good here, just keep em coming...
