What is back saw?

A back saw is a type of hand saw with a stiffened spine along its top edge, which helps maintain a straight cutting line and provides greater control. It typically has fine teeth, making it ideal for precise cuts in wood, particularly in joinery or cabinetry work. Common types of back saws include the tenon saw and the dovetail saw, each designed for specific woodworking tasks. The rigid spine distinguishes it from other saws, allowing for cleaner and more accurate cuts.
