If you look at the work we do, you will note that most of it is round. so
if the bevel is alos rounded - concave- the bevel will sit on the wood
better so when the handle is lifted the edge wiil make contact in a more
complete manner than if the edge were made up of 1000 facets

This seemed intuitive to me, even after reading the oft-repeated behest to
get a grinder with larger wheels in some of the instructional books.

Also see George's explanation and my response. So I rephrase the question:
why is such a big deal made about larger-wheel grinders? I've seen the work
of many of you herein, and frankly I doubt if bevel concavity plays much of
a role pro or con.
