1) arcs are strong the convex edge is now reinforced by the concave arc of the hollow grind, and if done in a steel like 1095 or 80crv2, twisting while batoning wood shouldnt be a problem. now on a blade this size that point is kind of irrelevant, but on bigger blades like our Bowie or camp knife it becomes relevant.

You can hone quite a few times before the hollow is gone and grinding is necessary. Sharpening should not require spending big money. IMO it is sold as a black art that needs all manner of paraphernalia that is designed to take cash that could be better spent on a new L-N 4 ½ or some nice cherry stock.
