Due to its superior strength and simple design, the mortise and tenon joint has been used for centuries. Typically used to join two pieces of wood at a 90 degree angle, this joint is especially common in drawer construction. There are many variations of mortise and tenon joints, but each style involves a protruding tenon cut at the end of a piece of wood that fits neatly into a mortise, a hole in the corresponding piece of wood, which is then secured into place with an adhesive. Unlike dovetail construction, the mortise and tenon joint is usually hidden from view, though it rivals the dovetail joint in strength and durability.
