The combat knife is a melee weapon 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]


The military issue combat knife is a rather common melee weapon in Fallout 3. It is affected by the melee damage bonus from Strength. It is one of the better low-level melee weapons, and can get around 3-4 strikes in V.A.T.S. even with a reasonable number of AP and a fast swing speed outside of V.A.T.S. However it has extremely short reach, about that of an unarmed weapon. With 10 Luck, it becomes an extremely potent weapon that will critically hit almost once every 4 to 5 hits.

The combat knife itself has a single edge with a clipped point, with a serrated edge on the back. It is of the standard Bowie shape and it may have been modeled off the real-world KA-BAR military issue knife.


  • Occam's Razor, a slightly stronger version of the combat knife, wielded by Talon Company Commander Jabsco.
  • 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.
