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


The following section is transcluded from Combat knife. To modify, please edit the source page.

A high-quality military combat/utility knife,[1] the "Stallona" knife is made by SharpWit, Inc., using a funneled bowie shape and a stacked grip with a finger ring on the pommel (though some models may lack the ring and the funnel).[2] Certain models may have a serrated top edge[2] while others also lack this feature like the ring funnel.[3] The edge is guaranteed by the company to remain sharp for over a decade of use![4]


Occam's Razor is only stronger than the combat knife in raw damage by 3 points, so it may not be much more useful than a normal combat knife. It is inferior when compared to Stabhappy.


  • Combat knife, the common variant
  • Stabhappy, identical to Occam's Razor, but has two principle differences. Firstly, the raider that holds it respawns, allowing multiple copies to be obtained. Secondly, it deals an additional 50% damage to limbs.
  • Trench knife Operation: AnchorageGametitle-FO3 OA.png, identical to the regular combat knife. The only difference is a unique "knuckle-duster" skin.
  • Sim version trench knife Operation: AnchorageGametitle-FO3 OA.png, a sim-only version of the weapon which differs only in health (essentially non-degrading).
  • Swampfolk combat knife Point LookoutGametitle-FO3 PL.png, a non-playable version of the weapon used only by Point Lookout's swampfolk, this version has identical stats but has an object effect which inflicts an extra 35 damage per hit when used by non-player characters against the player. This damage ignores Damage Resistance and is independent of the condition of the weapon.

Found on Commander Jabsco at the Talon Company base in Fort Bannister.

Behind the scenes

"Occam's Razor" is a cultural reference to the scientific principle of the same name.


  • Xbox 360Icon xbox360.png PCIcon pc.png If the player 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.
  • PlayStation 3Icon ps3.png Xbox 360Icon xbox360.png PCIcon pc.png In the Broken Steel event in which the Brotherhood raids Fort Bannister, on certain occasions Occam's Razor will not be found on Jabsco or in the containers in the room that Jabsco is found in. This is due to a Brotherhood member picking the weapon up.
