called pinning. One way to help prevent pinning is by rubbing chalk between
the teeth before filing. However, the best method of keeping a file clean
is to use a file scorer and file cleaner brush (figure 101). A scorer is a
small pointed metal instrument, often furnished with the file cleaner brush.
It is used for cleaning out individual teeth and grooves in the file if they
become clogged too tightly with metal to clean with the brush.
When
cleaning a file with a file scorer, use a pulling motion, holding the file
scorer blade parallel to the rows of teeth. Finish cleaning by brushing the
file parallel to the rows of teeth with the file cleaner brush.

(3) Handling Precautions.
(a) Do not throw files in a drawer or tool box where they can rub
against each other, or against other tools. Store them in separate holders,
such as clips, straps, or in holes cut in a block of wood.
(b) Use a file as instructed, and clean files often.
(c) Never use a file without a securely attached handle (figure
102 on the following page) unless it is of the Swiss pattern.
