back saw
A short, fine-toothed hand saw stiffened by means
of a metal rib along its back edge. It is used to
saw-in the kettle kerfs and the grooves for
sawn-in cords. Although almost any small saw will
suffice in lieu of the back saw, it has the
advantages of being short, stiff and easy to hold.
It must be very sharp to avoid tearing the paper.
Also called "tenon saw."
