TYPES AND USES - Continued
COMPASS SAW
The compass saw is slightly larger than the keyhole
saw. The teeth are so arranged that the blade can easily
be turned for cutting curves or holes. As with the keyhole
saw, the compass saw will vary in size depending on the
design and purpose.
HACKSAW
The hacksaw is designed to cut almost any size or
shape of metal object. The hacksaw uses two types of
blades, hard and flexible. The type of blade used
depends on the nature of the task. The blade is held to
the saw frame by pins that fit into small holes at each end
of the blade. Blade tension is adjusted by a screw and
wingnut assembly at either the nose or the handle end of
the frame. The hacksaw comes in various designs, de-
pending on the purpose.
