A bloody knife, with a red handle.


The knife orbits Isaac, doing very high damage to any monster it touches. It is supposed to block tears, but often does not due to a bug.



  • This item's sprite is the same as Mom's Knife, but flipped upside down with blood on the blade and a red handle.
  • The in-game secret message refers to it as "Sacrificial Knife"
