For an overview of knife models in the Fallout series of games, see Knife.

The Ant's Sting is a unique knife found in Fallout 3, used by the AntAgonizer.


Ant's Sting poisons those injured by it, dealing an additional 4 damage every second for 10 seconds. Because poison damage stacks, rapidly hitting an opponent outside of V.A.T.S. can raise Ant's Sting's DPS to very high levels. After attacking 12 times within 4 seconds, its actual DPS rises to 90, outclassing the Shishkebab (without Pyromaniac). However, most enemies will already be defeated before Ant's Sting can pass this turning point. This effect makes this one of the most powerful melee weapons in the game.


Ant's Sting can successfully strike about 1250 times from full condition before breaking.


  • Knife
  • Slasher knife - Appears in Tranquility Lane and can only be obtained outside of the simulation through console commands.
  • Ritual knife Gametitle-FO3 PL - Even more powerful than the Ant's Sting, the ritual knife only uses 12 AP for each V.A.T.S. attack.
  • Toy knife Gametitle-FO3 PL - Using even less AP than the ritual knife, 10 compared to 12, the toy knife uses the lowest amount of AP for any weapon in Fallout 3. However, it does very little damage, much less than the regular knife.
