The cosmic knife clean is a weapon in the Fallout: New Vegas add-on Dead Money.
Characteristics[]
Compared to the standard cosmic knife, the cosmic knife clean's primary benefit is that it inflicts 3x damage to limbs, twice that of the unclean and nearly twice that of the super-heated version. It also deals the highest damage per strike, the highest critical hit damage and has the highest durability of the three cosmic knife variants.
Visually, the weapon is almost identical in appearance to the unclean knife, save for being completely cleaned of the Cloud residue and replacing the dirty purple hue with a sanitary shine on the blade.
Special attack[]
The cosmic knife clean has a special Surgical Strike attack, which does 150% damage in V.A.T.S. at the cost of 5 more action points (requires a Melee skill of 50).

It is possible to execute Surgical Strike 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.
Durability[]
The cosmic knife clean can successfully strike about 995 times from full condition before breaking.

Notes[]
- The weapon's bonus limb damage allows it to quickly dispatch ghost people due to them being scripted to die instantly if a limb is crippled.
- Christine's companion AI prefers to use the Cosmic knife clean over the knife spear clean, despite both weapons having the same DPS.
Behind the scenes[]
 | The following is based on Fallout: New Vegas cut content. |
|---|
Shape and texture resources for the cosmic knife, its clean, and super-heated variant are all present in the files of the Old World Blues add-on, but not used. Though present, no objects in the add-on use these resources. The resources are stored within the nvdlc01 folder used by the Dead Money add-on, rather than the nvdlc03 folder allocated to Old World Blues.
