A back saw is a type of hand saw characterized by its stiffened back, which helps keep the blade straight during cutting. This design allows for precise cuts, making it ideal for woodworking tasks such as joinery and fine detail work. Back saws typically have fine teeth, which contribute to their ability to create smooth edges. Common types of back saws include the dovetail saw and the tenon saw. The dovetail saw is used for making intricate cuts, while the tenon saw is designed for cutting tenons in joinery. Both tools are essential for carpenters and woodworkers who require accuracy in their projects.
