Jason Voorhees does not use a chainsaw.
He is primarily known for wielding a machete and other sharp weapons. However, he is known for his use of other tools and implements, including:
* A pitchfork: In "Friday the 13th: The Final Chapter"
* A spear gun: In "Friday the 13th: The Final Chapter"
* A pickaxe: In "Friday the 13th: Jason Takes Manhattan"
* A harpoon: In "Jason X"
While a chainsaw isn't part of Jason's arsenal, it's often associated with horror movies. The iconic slasher villain Leatherface from the "Texas Chainsaw Massacre" series utilizes a chainsaw, which might lead to some confusion.
