Leo are you trying to confuse George with facts again? ... chuckle(tm)

Nope, we still measure wood strength by resistance to force per unit of
area, so dividing the force over a larger area, as always, is the best way
to ensure that the material is not deformed. No ridges or teeth, contour
meets contour is the best.

Those are facts. What's nice to know is that you can use bad practice and
still get good results when you use jaw types designed to divide the load,
and carry it over a broad area.
