“Steve, the reason the back of any blade needs to be flat has nothing to do with a “wedge” or “geometry” or arguing.

It has everything to do with sharpness. Two points intersecting cannot produce a sharp edge if one of them is not flat. Simple. It’s just a physical fact.”

That was always my understanding….it was tied to the sharpness. Same with plane blades.
