Donkey Jawbone is a passive item.


  • When Isaac takes damage, a spin attack will damage enemies around him, doing his current damage with a multiplier.
    • The spin attack blocks projectiles.
    • When an enemy is killed with the spin attack, it has a chance to drop a red heart on the floor.


  • 20/20: Grants 1 additional spin.
  • Ipecac: Spin attack poisons enemies.
  • Menorah: Upon taking damage, Menorah's multiplier is incremented before increasing the number of spins accordingly.
  • Mom's Knife: The jawbone is thrown forwards in the air and spins several times before returning to Isaac.

In-game Footage[]


  • This item is a reference to a passage from the Book of Judges in which Samson kills one thousand Philistines using only the jawbone of a donkey.
  • This item originated from the Binding of Isaac: Community Remix mod, being known as 'the sword' before release.[1]
    • In the Binding of Isaac: Community Remix, this item was similar to Mom's Knife. It was changed to the way it is now due to Samson's changes in Rebirth.
  • Donkey Jawbone was one of the few items not imported into Repentance, alongside Book Of Despair, Bowl of Tears, Knife Piece 3, Menorah, Stone Bombs, and Voodoo Pin. It was replaced by Bloody Gust. However, its sprite was implemented as the weapon used by Tainted Samson.
