A
saw is a
tool consisting of a tough
blade,
wire, or
chain with a hard toothed edge. It is used to
cut through material, most often
wood. The cut is made by placing the toothed edge against the material and moving it forcefully forth and less forcefully back or continuously forward. This force may be applied by
hand, or
powered by
steam,
water,
electricity or other
power source. An
abrasive saw has a powered circular blade designed to cut through metal.
