Knock-Knock

 is a unique weapon in Fallout: New Vegas. It is a unique variant of the fire axe.

Characteristics
The axe head appears to be either unpainted or the paint has been completely chipped away. The Knock-Knock namesake is a reference to the real world application of this type of fire axe as a forced- entry tool. Knock-Knock has a special move (50 Melee Weapons) in V.A.T.S. called Mauler, which can knock enemies down, but costs significantly more action points. Mauler will sometimes knock a weapon out of an enemies hand instead of knocking them down.

Locations
Found in Camp Searchlight's Fire Station. Once you get the key from Logan, head upstairs and search the bathroom stalls, look in the right side corner of the stall with the Skeleton to find the Knock Knock. You must first complete the quest for Logan to get the key or you can kill Logan.

Appearances
