Machete

A machete is a large, knife-like weapon, used throughout the series. It is mostly used by Jason Voorhees in most of the films and was possibly his favorite weapon, as he used it whenever possible. It was also used by William Brown, Alice Hardy, Pamela Voorhees, Ginny Field, Roy Burns, Freddy Krueger, Tommy Jarvis, and Trish Jarvis.
