The joining of two timbers by bevelling off the edges so that the same thickness is maintained throughout the length of the joint. In the construction of a wooden ship, the stem and sternposts are scarfed to the keel. A scarf which embodies a step in the middle of the joint, so preventing the two parts from drawing apart, is called a lock scarf. It is a joint of great antiquity, having been used in early Egyptian and Phoenician shipbuilding.
