TM 9-243 TYPES AND USES Saws are tools with thin, flat steel blades that have a row of spaced notches or “teeth” along the edge. The blade is fastened to a handle. Saws are available in various sizes and designs depending on their use and the mate- rial to be cut. The most common types of saws are handsaw, (crosscut and ripsaw), backsaw, one-man crosscut saw, two-man crosscut saw, nested saw (keyhole and compass) and hacksaw. ONE-MAN CROSSCUT SAW HANDSAW The handsaw consists of a thin flat blade with teeth and a wooden or plastic handle, called the heel, fastened to the end of the blade by screws. There are two categories of handsaws: the ripsaw (1) and the crosscut (2). The ripsaw is designed to cut with the grain of wood, and the crosscut saw is designed to cut against the grain. The handsaw is used in carpentry, rough-out work, and for “finish” hand sawing. Sizes of handsaws vary depend- ing on design and nature of the task. The one-man crosscut saw is about 36 inches long and has a handle at one end. This type of saw is charac- terized by a high-grade steel blade with two types of teeth known as “cutters (1) and “rakers” (2). The cutters do the cutting, and the rakers chisel out and remove chips from the cut. It is used for heavy work such as cutting down trees and sawing heavy timbers. 46-2
