The knife spear clean is a weapon in the Fallout: New Vegas add-on Dead Money.


The knife spear clean is a two-handed melee weapon. It is similar in appearance to the regular knife spear, but it does 5 more DAM, has a higher critical hit chance and causes bonus limb damage.

Special attackEdit

It has a special attack called Mauler, which does normal damage in V.A.T.S. at the cost of the normal 35 action points, but adds a chance to knock down opponents (requires a Melee skill of 50).

Mauler5050351.43Knockdown chance
Note: Melee weapons do double normal damage in V.A.T.S.

It is possible to execute the Mauler attack outside of V.A.T.S. (without the required Melee skill of 50) by initiating a power attack (hold attack button) while moving forward.


The knife spear clean can successfully strike about 1995 times from full condition before breaking.


This weapon must be crafted by the player character. It cannot be found on enemies or in containers. The workbench recipe is listed as "cosmic knife spear," but the weapon will appear in the player character's inventory as "knife spear clean."

While the DPS is the same as a regular cosmic-knife clean, this weapon has a higher DAM per attack which makes it more effective against enemies with high DT.


  • PCIcon pc Playstation 3Icon ps3 Xbox 360Icon xbox360 This weapon appears mostly identical to the standard knife spear, notably the knives themselves, which do not appear to be clean. This is caused by the special, "clean" texture for the weapon only being applied to the staff portion of the weapon and not the blade portion. [verified]
