A power tool designed to efficiently cut trees by means of a motorized chain with serrated edges, hence the term chainsaw. Chainsaws usually consist of a two-stroke gasoline engine, but with electric power being more commonplace, some chainsaw brands are electric-powered. However, in popular culture, the chainsaw has gained notoriety as a potential weapon or an instrument of torture and/or gruesome murder, most famously in the movies Texas Chainsaw Massacre
, and Scarface
. The chainsaw has also been featured in video games such as Doom 3
and Resident Evil 4
, where it has become an icon.
In Resident Evil 4, the player can be gruesomely decapitated by Doctor Salvador or The Bella Sisters, the main chainsaw-wielding enemies of the game.
