A
backsaw is any
hand saw which has a stiffening rib on the edge opposite the
cutting edge, allowing for 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. Because of the stiffening rib, backsaws are limited in the depth to which they can cut. Backsaws usually have relatively closely spaced teeth, often with little or no set.
