Big Jim (weapon)

Big Jim is a unique pipe wrench found in Fallout 4.

Gameplay
A unique pipe wrench that bears the Kneecapper effect, which allows every hit to have a 20% chance of crippling the target's leg.

Location
Big Jim is on a metal set of drawers under the gift shop at Walden Pond. The door to the basement is Master-level locked, but a note to the side of the door mentions an unlocked sewer entrance inside the big pipe at the pond. Alternatively, the door can be accessed by acquiring the key from Walter, a raider at Walden Pond.
