oh this thread again...
cool new posts, i love sword cutting data...
since i test many of my swords on wood ( i live in a forest, after all ), i find that the chisel edge is not good on hard targets. i cut 2 by 4s in one swipe with v-grinds but experienced too much deflection with chisel grind, and that deflection also resulted in damage due to side loading. it still would seem to me that the biased cutting ability in the cg would help in cutting unstable, soft targets like free hanging rope or tatami, at least in one direction. humans are also not symmetrical!
