Hammer (Fallout 3)

The hammer is a miscellaneous item item in Fallout 3 and Fallout: New Vegas

Fallout 3
It is useful only as Rock-It Launcher ammunition, which can usually be found near workbenches. It cannot be used to repair anything or as a weapon.

Fallout: New Vegas
In Fallout: New Vegas, hammers don't serve any practical purpose. There is no reason to collect them, unlike for instance, wrenches, which are used in the creation of weapon repair kits

Locations

 * Hammers are commonly found on workbenches or near toolboxes.
 * Hammers are usually seen next to, or near, a wrench.
 * A slightly larger sized hammer can be found in the Temple of the Union near Caleb Smith's workplace, on top of a metal bench-object.
 * A slightly smaller than average hammer can be found right next to the giant hammer, on the floor next to a bottle of turpentine and a toolbox. For size comparison, a regular hammer can be found within Caleb Smith's room.
 * Both size variants of the hammer can be taken freely, without being considered stolen.
