A Tenon Saw (Backsaw)
Tenon saws are used for accurate, straight cuts in small pieces of wood.
The back of the saw limits the depth of the cut. The brass or steel
back stiffens the blade and provides sufficient weight to cut. This
increases the accuracy of the cut. The tenon saw is used to cut small
pieces of wood and most joints.
The tenon saw is the most used backsaw.
