The slasher knife is the signature weapon of the Pint-Sized Slasher. It can only be found in the Tranquility Lane simulation. Outside of Tranquility Lane, it cannot be obtained without console commands.


The knife does a lot more damage than a normal knife - more than twice that of any other knife in the game. This results in it almost always dismembering the target. It can be repaired with other knives, including unique variants.


  • Knife, the common variant.
  • Ant's Sting, a slightly stronger knife that deals poison damage over time.
  • Ritual knife Point LookoutGametitle-FO3 PL.png, a knife even more powerful than the Ant's Sting that uses less AP.
  • Toy knife Point LookoutGametitle-FO3 PL.png, a knife that uses the lowest amount of AP for any weapon in Fallout 3. However, it does very little damage, much less than the regular knife.

Main article: Tranquility Lane

The knife is obtained along with the Pint-Sized Slasher mask during the Tranquility Lane quest if you decide to help Betty kill all the residents of Tranquility Lane. It is then located in the doghouse beside the abandoned house and is automatically equipped when you receive it.

At the end of the quest or upon exiting the simulation, the knife is automatically removed from your inventory. The glitch which allows you to take items out of the Anchorage Reclamation simulation does not work here due to the fact that it is a "quest item" and cannot be removed from the player.


  • When acquiring the knife by using console commands, using the command player.unequipitem once allows you to equip and unequip them as normal. It is impossible to get off your character without using the command player.removeitem (since they are quest items).
  • The item has no assigned icon, displaying the placeholder icon "PipOS Error #-26 (File Not Found)" in inventory.
