Sledgehammer (Fallout: New Vegas)

The sledgehammer is a weapon

Characteristics
The weapon consists of a long wooden shaft and a metal hammer head.

Special attack
It has a special Mauler attack that does 50% damage in V.A.T.S. at the cost of 10 more Action Points, but also has a chance to knock down enemies (requires a Melee skill of 50).

It is possible to execute Mauler outside of V.A.T.S. (without the required Melee skill of 50 to perform the move) by initiating a power attack (hold attack button) while moving forward.

Durability
The sledgehammer can successfully strike about 745 times from full condition before breaking.
