The tenon saw is a tool that is used primarily in the cutting of wood tenons which are a kind of interlocking joint or hinge. It is a member of the backsaw family and is typically made with a hardened metal edge with cross-cut files or rip-filed teeth.
Tenon saws come in many different styles and sizes and have been around for centuries. While the style of the tool has changed a bit through the years, it is still the primary saw that woodcrafters and furniture makers use for cutting tenons. The majority of tenon saws consist of a rectangular metal blade that is mounted on a stylized or wooden handle. Some tenon saws feature a pistol grip-like handle that allows for different kinds of leverage.
