No, the drawing was made too hastily to be accurate in that respect.
I am starting to be confused. Are you still disputing my simple observation that a wedge is beefier, also at the cutting bevel?
Imagine that we would hone a wedge, and next regrind it to a full hollow, without damaging the very edge. It can't be that hard to see how the lower part of the original bevel would be ground away too leaving less wide bevel panes.
No?
