Yep. 100% with you there. It was the "height" thing that I don't think should have been there.

In this case the wider bevel will be a bit sturdier, because it contains more steel for the same height. (it has a wider base).
See, I read that as "height of the bevel". Now I'm thinking you meant height of the bevel for the wedge case and at that same height (which would extend above the bevel in the hollow case). I was pretty sure I understood what you were saying but like I said, I thought maybe you didn't type it quite right?
