Bevel

Bevel is a sloped or canted surface resembling a chamfer or splay, excepting that in strictness this latter term should be applied only to openings which have their sides sloped for the purpose of enlarging them, while a sloped surface in another situation would be a bevel; this distinction, however, is seldom regarded. and the two terms are commonly used synonymously, SEE CANT; SEE SPLAY.
