Bear Trap (Fallout 3)

The Bear Trap is a weapon $$

Gameplay
Bear traps are a spring-operated pair of spiked jaws that snap shut on one's leg should the pressure switch in the middle be triggered. This can cripple the limb at lower levels. A Repair skill of 25 is required to disarm them. Shooting the switch or dropping an object on it also works. Bear traps can be reset, but this requires a Repair skill of 55.
