A mortise and tenon joint is a traditional woodworking technique used to connect two pieces of wood. The joint consists of a rectangular hole, called a mortise, cut into one piece, and a matching projection, known as a tenon, on the other piece. When assembled, the tenon fits snugly into the mortise, creating a strong and stable connection. This type of joint is commonly used in furniture making and construction, providing durability and strength. It is often found in items like tables, chairs, and frames. The mortise and tenon joint has been used for centuries, showcasing the craftsmanship of woodworkers throughout history.
