Chainsaws used as a weapon. Basically, chainsaws are good. Good here having the meaning of "totally unstoppable weapons of mass destruction." Nothing can stand before their roaring, multi-toothed might; only death awaits any who challenge a chainsaw-wielding maniac. Death and Gorn. Since they're usually used in media where carnage is key, chainsaws are typically a favorite tool of Ax-Crazy lunatics, horror villains, and survivors of the Zombie Apocalypse (both good and bad).
