Chamfer Chamfering is a technique by which a furrow or groove is cut. In clock- and watchmaking, chamfering refers to the bevelling or cutting of a furrow into decorative features, such as chamfered apertures, chamfered minute and hour hands and the chamfered corners of clock cases. In carpentry, to chamfer is to cut away a right-angled edge or corner or to make a symmetrical sloping edge. For an example of chamfered features on early British timekeepers, see the corners of the clock case on the Red Turtleshell Table Clock made by Daniel Quare around 1700, and the delicately chamfered foliate hour hand on the dial of the Gold Cylinder Watch, made by George Graham and hallmarked 1733. Both timekeepers are exhibited on Clocktime.
