Optimum size is that which puts the greatest amount of metal against wood
without distorting the latter. The quarter-circle types have an optimum size
of circularity plus or minus perhaps 5%. I call this the optimum situation,
because any deformation makes realignment after a dismount more difficult.
The status quo ante just no longer exists. The weakness of the Oneway
design is that it has to "grip" by distorting or destroying the integrity of
the portion gripped.

i have not found the ribbed oneway jaws to be as distructive as you make them
sound. a screw may distort or "destroy" more wood fibers than a nail does but
the screw still holds better. im not saying the way you do things is wrong.
if dovetail jaws work better for the work you do and the way you do it than
thats what you should use.
