Hand saws are used in carpentry and woodworking to cut pieces of wood into different shapes. A series of sharp points obtained from a material stronger than wood. A handsaw looks a lot like a tongue saw, but with a flat, sharp edge. The main material for making the saw blade is high quality hardened tool steel mixed with other metals. Handles were only wood, but modern tools can also be molded plastic. To cut wood, use a handsaw. For metal, you will need a hacksaw. Precise woodworking requires precise cutting.
