Nephi's golf driver is a unique golf club utilized as a two-handed weapon. Compared to its more common variant, the 9 iron, it is in more pristine condition and appears to be straight rather than old and battered. It has better critical damage but is more brittle than the standard golf club.
It is possible to executeFore! 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, however, it may not knock the target down on impact.
The Vault Boy Pip-Boy image for this weapon differs from the image for the 9 iron.
The knockdown effect is guaranteed against even the most powerful of opponents. This makes it possible for a low level player to take on enemies that would otherwise be extremely difficult or impossible.
