Man Opener

The  is a melee weapon found in The Pitt add-on. It is a unique auto axe.

Characteristics
Though the weapon has less damage than The Mauler, the Man Opener ignores normal damage resistance, similar to the deathclaw gauntlet. This property makes it more useful in some situations; for example, when going up against a mirelurk hunter or Enclave Hellfire Trooper. Perhaps the best way to describe it is to call it an "automatic deathclaw gauntlet."

Location
The weapon is found on a bed in the back of the Supply Plant in the Pitt Steelyard close to a single steel ingot.

Enter the Supply Plant, then go east through the hallway. Turn north and continue until you reach two exits. Take the left. Continue through the passage, climb the stairs, and eventually exit into a large room. There's a bed on the left as you enter. The Man Opener is on the bed.
