Chainsaw

A  is a portable motorized automatic cutting instrument used to cut materials (usually wood) more quickly than a traditional, and has found its common use in both lumberjacking and in home gardening. Chainsaws are so-named because their cutting blades rapidly move attached to a rotating chain. The tools are famous for being very noisy when in use.

Because of the rapidly spinning blade, chainsaws are also extremely dangerous to use without care and caution, as the blades can cut living flesh and bone just as easily as they can cut wood. This extreme hazard has influenced the fictional use of chainsaws as a deadly weapon, made famous by the 1977 slasher film .
