Which type of saw is specifically designed for cutting metal?

A hacksaw is specifically designed for cutting metal due to its serrated blade and adjustable tension. The blade typically has a finer tooth count, which allows it to effectively cut through metal materials, such as pipes, sheets, and rods. This design is crucial because metal requires a specific cutting action to prevent damaging the blade and ensure a clean cut.

In contrast, a handsaw is generally intended for woodworking, featuring larger teeth that are better suited for cutting through softer materials like wood. Although a coping saw and a keyhole saw serve specialized purposes—cutting curves in wood and making intricate cuts in thin materials respectively—they are not designed for cutting metal. Therefore, the unique design and focus of the hacksaw make it the appropriate tool when working with metal.
