Nail Board (Fallout: New Vegas)

The nail board is a weapon

Gameplay
This 2x4 has several nails driven through it, with a whittled shaft to ensure a better grip. It looks identical to the version in Fallout 3, and is still used by Super Mutants.

Special attack
It has a special Grand Slam attack that does 200% damage in V.A.T.S. at the cost of 11 more action points and requires a Melee skill of 50.

It is possible to execute Grand Slam 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 nail board can successfully strike about 295 times from full condition before breaking.
