I find it strange that the scycle/scythe blade design was simply abandonned. The only other examples I've seen of such curvature are african weapons like zairian throwing knives and executioner swords. One question bugs me: From a functional/physics point of view how is the concave edge more or less effective than the convex? The convex focussed all cutting power at the apex of the curve, does that apply to concave as well?  
 
My appreciation for any answers.
