—The back-saw, or tenon-saw as it is often called, has a thin blade strengthened by a heavy steel back piece. It is used upon work requiring delicate, accurate cutting, [Fig. 29]. [Fig. 30] shows the shape of the teeth, which differ slightly from those of the cross-cut. These teeth are suitable for both cross-cutting and fine ripping. But little set is given the teeth of the back-saw.

In using this saw, [Fig. 31], hold the work firmly against the stop of the benchhook with the left hand, guiding the saw with the forefinger or thumb placed against the blade just above the teeth. Begin on the backward stroke, holding the handle end of the saw highest. Begin at the farthest corner, using short, easy strokes. Gradually lower the handle to a horizontal position, meanwhile increasing the number of teeth used, but continuing the slow, regular strokes.
