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 Mauler attack that 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).

Note: Melee weapons do double normal damage in V.A.T.S.

It is possible to execute Mauler 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.


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


This weapon must be crafted by the player. 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's inventory as "knife spear clean".

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


  • pcIcon pc ps3Icon ps3 xbox360Icon 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]
