Tolsen Mitre Box with Back Saw Set

A backsaw is any hand saw which has a stiffening rib on the edge opposite the cutting edge, enabling better control and more precise cutting than with other types of saws. Backsaws are normally used in woodworking for precise work, such as cutting dovetails, mitres, or tenons in cabinetry and joinery.

A mitre box or miter box is a wood working appliance used to guide a hand saw for making precise cuts.
