The Tenderizer (Fallout 3)

The Tenderizer is a unique sledgehammer $$

Gameplay
Given its name, ability, and location (a mirelurk butchery), it is likely this weapon was originally used for literally tenderizing mirelurks.

Durability
The Tenderizer can successfully strike about 500 times from full condition before breaking.

Variant

 * Sledgehammer - the common variant.

Location
It is located inside the Anchorage Memorial, in the utility room with the broken door. To find the door, enter the Memorial Service Entrance on the east side of the memorial. At the junction, turn left to find the second door on the right. The door can be fixed by finding the door component, but a Lockpick or Science skill of 50 is required to be able to open the safe in which the door component is stored in the top level of the building. One can look behind the Nuka-Cola dispenser to obtain the passcode for the computer in the same room, which will then unlock the safe. A Repair skill of 35 or higher is required to fix the door with the help of the component. Without the component, a Repair skill of 95 is required.
