Occam's Razor is a unique combat knife in Fallout 3.


Commander Jabsco's personal weapon, Occam's Razor, is stronger than the basic combat knife in raw damage by a total of 3 points. It is aesthetically identical to the normal variant.


Occam's Razor can successfully strike about 1200 times from full condition before breaking.


  • Combat knife - The standard variant.
  • Stabhappy - Stabhappy shares all of its stats with Occam's Razor, except it deals an additional 50% damage to limbs.
  • Trench knife Operation: Anchorage (add-on) - The trench knife's stats are identical to the regular combat knife. The only difference is a unique "knuckle-duster" skin.
  • Sim version combat knife Operation: Anchorage (add-on) - A sim-only version of the combat knife which differs only in health (essentially non-degrading).
  • Sim version trench knife Operation: Anchorage (add-on) - A sim-only version of the trench knife which differs only in health (essentially non-degrading).

Behind the scenes

The name of this weapon is a reference to the problem-solving principle of the same name.


PCPC Playstation 3Playstation 3 Xbox 360Xbox 360 If the Lone Wanderer kills Jabsco without shooting him, such as by hacking the turrets or reverse-pickpocketing a grenade, Occam's Razor won't appear in his inventory. This can be fixed by shooting his corpse. [verified]
