Fig. 106. The back saw
The back saw, being strengthened by a heavy piece of steel along the top, is made of thinner material, and the tapers are not necessary, for the back piece gives rigidity. It removes less wood, but is limited in its action by the back. It is used chiefly by pattern makers, and for finer bench work, such as cabinet making, but should be part of every boy's outfit.
The compass-saw shown at [Fig. 107] is used for general purposes, but is not so necessary as the back saw. It is useful for cutting out small openings, though it is not as valuable for this purpose as the turning saw.

One end of the turning saw can be released from the frame by removing a pin, passed through a small hole. This is fastened in the frame again and made to follow a curved line like a fret or coping saw.
