A saw uses a row of teeth that act as a succession of cutting edges. The size and shape
of the teeth vary in different saws. This means that a saw may be suitable for one type of
work but unsuitable for another.
A good saw needs accurate set as well as sharpness. Set
allows the saw to cut without clogging, due to the teeth being bent out from the blade, with
alternate teeth in opposite directions. It is this facility which allows the line of cut to
be adjusted as you work along the wood.
The handle of the saw is important for both strength
and comfort. Wooden handles are useful when the saw is going to be used for long periods of
time as it absorbs perspiration. Plastic handles may not be as comfortable to hold as wooden
ones, but they are often stronger.
Take care of the saw when it is not being used. It should
be kept out of reach of children - hang them up in an upright position. Oil the blades before
storing to prolong the life of the blade and prevent rust forming.
