Chainsaw

A chainsaw is a mechanical saw used for cutting up wood. It is used by lumberjacks and landscapers who need to cut through thick tree trunks, branches and timber. It is also used to help chop up firewood. A chainsaw typically uses a two-stroke gasoline engine and a cutting chain secured to a guide bar on top of rollers.

In the 1981 slasher film, Friday the 13th Part 2, the character of Ginny Field used a chainsaw to chop up some wood. She later used it to defend herself against deranged murderer Jason Voorhees, and was able to force him to retreat.
