The combat knife is a weapon in Fallout: New Vegas.


A large knife designed for both combat and survival purposes. It has a long, clip-point blade with serrations along the back intended for cutting rope and small branches.

This weapon qualifies as an improved holdout weapon.

Special attack

It has a special Back Slash attack, which does 70% damage in V.A.T.S. at the cost of 3 fewer action points (requires a Melee skill of 50).

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

It is possible to execute Back Slash 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 combat knife can successfully strike about 445 times from full condition before breaking.


  • Chance's knife - A much more powerful variant located in Chance's grave.
  • Assassin - The Caesar's Legion assassin sent to kill President Kimball carries a special version which is "non-playable". This prevents the weapon from normally being shown in inventory, e.g. when pickpocketing the assassin. The weapon is otherwise identical to the standard combat knife.
  • Cass - Rose of Sharon Cassidy carries a special "non-playable" version of the weapon, also otherwise identical to the standard version.
