BEVEL, the inclination of one surface of a solid body to another, also any angle other than a right angle, and in carpentry or joinery the angle to which a piece of timber must be cut. The tool known as a bevel is a rule with two arms that can be set at any angle. In heraldry, a bevel is an angular break in a line. Bevelment or bevelling is a term in crystallography expressing the replacement of the edge of a crystal by two planes equally in clined to the planes adjacent to them. In architecture, a bevel is any sloped edge, or the surface resulting when the corner of a beam or other member is cut off at an angle. The term bevel is used especially when the resultant surfaces are relatively small; the term splay is used when they are large. Bevel is used also to describe the sloped surfaces between the projecting faces and the recessed joints of rusticated masonry.
