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 essential for woodworking and carpentry, providing precision and control. They are often preferred for smaller projects or detailed work where power tools may be too cumbersome. Proper technique and maintenance can enhance their effectiveness and lifespan.
