Backsaws are used for general bench work such as cutting joints and smaller sections of lumber to length. Sizes vary depending on design and nature of work. NESTED SAWS The two-man crosscut saw is 5 to 6-1/2 feet long with a handle at each end. As with the one-man crosscut saw, it also has a high-grade steel blade with the “cutter” and “raker” teeth arrangement. It is used when two men are required for extra heavy cutting jobs. BACKSAW Nested saws consist of a wooden handle to which sev- eral different blades can be attached, making up differ- ent types of saws such as the keyhole or compass saw. A slotted end at the heel of each blade slips into the pistol-grip type handle where a wingnut fastens it in place. Nested saws are used to cut along curved lines, to start cuts for larger saws, or to make starting saw cuts from drilled holes or small openings. The size of these saws will vary depending on design and nature of use. KEYHOLE SAW The backsaw has a straight blade and parallel top and bottom, with a heavy strip of steel or brass wrapped along the back to provide rigidity. The handle is of similar The keyhole saw is the smallest type of nested saw. Its blade has a very narrow point small enough to enter a 1/4-inch hole.
