Usage & Description

The Psycho Stabber is the bread and butter of any melee build that isn't using the Face-Puncher. It provides the highest melee damage bonus of any weapon in the game. It is especially effective with Amara's Phaseflare, vastly improving the skill.

As a gun, it is an ineffective option with its weak damage and limited projectile range.


  • The +340% melee damage comes from two separate melee accessories which grant +300% and +40% melee damage.
  • Holding the Psycho Stabber massively increases the damage of the Fish Slap grenade mod and the Stinger shield's Nova.


  • The source, name, and special effect of the weapon are a reference to the 1960 film Psycho.
  • The flavor text is a reference to the song Psycho Killer by Talking Heads.
