- For the Genocide Route counterpart and the item found at the beginning of the game, see Real Knife or Toy Knife.
The Worn Dagger is a weapon item found in a gift box in Asgore's Home. Similar to its defensive counterpart, the Heart Locket, it is a Neutral Route counterpart of the Real Knife. It is associated with the first human.
When it is equipped and used to FIGHT, it depicts a curled, red slash animation. This animation and sound it makes is shared with the Stick, Toy Knife, and Real Knife.
