Tinker has a hook for a right hand.
Tinker attacked Michelle and Ryan in a truck and threw a dead coyote at their windshield. He later encountered Benny and offered his assitance, setting down road flares, but Benny discovered that he was intending to kill them when he saw a damaged chainsaw in his truck. Tinker unsuccessfully tried to run Benny down.
Tinker later brought in Ryan after he was severely injured by Leatherface. He also made a gold chainsaw that had "The Saw is Family" engraved on it, for Tex to give to Leatherface. When Benny was shooting at the cannibals' house, Tinker's ear was shot off, as well as two of his fingers.Presumably he died of a blood loss.
