If you're going to be cutting something harder like 2x4s or saplings or coconuts, you don't want a hollow ground as it will crumple. Same thing when a straight razor hits a bone, belt buckle, or other hard objects. There's not enough behind the edge to support the shock. My personal opinion is that razors have evolved to the angles they have because they work for customers and shave well. It's a fun topic to talk about.
