A hand saw is a simple tool used for cutting wood and other materials. It consists of a long, flat blade with sharp teeth along one edge, attached to a handle for grip. Hand saws come in various types, such as the crosscut saw for cutting across the grain and the rip saw for cutting along the grain. Using a hand saw requires manual effort, making it a popular choice for DIY projects and woodworking. Unlike power saws, hand saws are quieter and more portable, allowing for precise cuts in tight spaces. They are essential tools for carpenters and hobbyists alike.
