WHEW!! I'm glad you guys posted your feelings. I was fully prepared to be tarred & feathered for posting any dislike of the vaunted RMD <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
The 511 appears to have more of a convexed bevel than that of a flat sabre grind found on the S5 or RMD. May just be my eyes playing tricks...but it sure feels like it to me. I don't think it's a flat sabre grind.
