A hand saw is a manual tool used for cutting wood and other materials. It consists of a long, flat blade with sharp teeth along one edge. Users grip the handle and move the saw back and forth to create a cut. Hand saws come in various types, including the crosscut saw for cutting across the grain and the rip saw for cutting along the grain. Hand saws are commonly used in woodworking, carpentry, and DIY projects. They are valued for their simplicity and portability, making them accessible for both professionals and hobbyists. Unlike power saws, hand saws require no electricity, allowing for use in remote locations.
