A bevelled edge (UK) or beveled edge (US) is an edge of a structure that is not perpendicular to the faces of the piece. The words bevel and chamfer overlap in usage; in general usage, they are often interchanged, while in technical usage, they may be differentiated as shown in the image on the right. A bevel is typically used to soften the edge of a piece for the sake of safety, wear resistance, aesthetics; or to facilitate mating with another piece.
