A steel bow saw is a type of hand saw that has a narrow, curved blade mounted on a metal frame or "bow." The blade is usually made of hardened steel and has a series of teeth along the cutting edge. The bow of the saw provides tension to keep the blade taut and allows the user to apply force and control to make precise cuts. Steel bow saws are commonly used for cutting through wood and other materials, such as plastic or PVC piping. They are often used in construction, woodworking, and landscaping.
