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 ...

Hacksaw blades have a hole at each end for mounting them in the saw frame and the 12 inch / 300 mm dimension refers to the center to center distance between these mounting holes. [4] The kerf produced by the blades is somewhat wider than the blade thickness due to the set of the teeth.
Although the coping saw is often used for similar work, the fretsaw is capable of much tighter radii and more delicate work. It has a distinctive appearance due to the depth of its frame (typically between 10 and 20 inches (25 and 51 cm)), which together with the relatively short five-inch (13 cm) blade makes this tool appear somewhat out of proportion compared with most other saws.
Scroll saws are classified according to the size of their throat, which is the distance from the blade to the rear frame of the saw. The throat depth determines how large a piece of wood can be cut. Smaller saws have a throat of as little as 12 inches (300 mm), while commercial saws can approach 30 inches (760 mm).
