I like them sharp, whether convex or flat bevel edge. But I just find that even when I use a stone, my edges are more convex than flat, so what the heck? It's easier for me to do a convex edge on a belt sander anyway, much smoother than using the platen. It isn't a huge difference anyway unless you have a full convex zero edge. That makes an uncanny difference in a chopper. But any edge that is sharp will do. The edges I have seen on the S5 pics appear to be pretty good. I have sharpened flat edges with a strop, and convex edges with a ceramic rod. It's just no big deal. Sharp is sharp. <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
