The mortise and tenon joint is a traditional woodworking technique used to connect two pieces of wood. The mortise is a rectangular hole cut into one piece, while the tenon is a matching projection on the other piece that fits snugly into the mortise. This joint provides strength and stability, making it ideal for furniture, doors, and frames. This method has been used for centuries in various cultures, including ancient Egypt and China. It is favored for its durability and ability to withstand stress, often seen in high-quality craftsmanship. The mortise and tenon joint remains popular among modern woodworkers for its effectiveness and aesthetic appeal.
