A coping saw is a type of hand saw used to cut intricate external shapes and interior cutouts in woodworking or carpentry. It is widely used to cut moldings to create coped rather than miter joints. It is occasionally used to create fretwork though it is not able to match a fretsaw in intricacy of cut, particularly in thin materials. Coping saw blades are always thicker and much coarser cutting than typical fretsaw blades and many others of its family members. A coping saw consists of a thin, hardened steel blade, stretched between the ends of a square, c-shaped, springy-iron frame to which a handle is attached. The blade is easily removed from the frame so that the blade can be passed through a drilled hole in the middle of a piece of wood. The frame is then re-attached to the blade and the cut starts from the middle of the piece. Long cuts perpendicular to the edge of the material are possible but the shallow depth of the frame rather limits how far from the edge one may cut.
