Notched Axe is an activated item.


  • Removed in Repentance Isaac holds the Notched Axe above his head as long as he is in that room, and can break any obstacles he touches, as well as being able to break through walls that lead into Secret Rooms.
  • Added in Repentance Isaac stops shooting tears and holds the Notched Axe like The Forgotten The Forgotten's club, and can break obstacles, blow open doors, and hit enemies for 3x damage by swinging it. Hitting rocks or enemies or opening doors with the Notched Axe decreases its charge. Isaac can toggle back and forth between tears and using the Notched Axe by pressing the Active Item button. Once the Notched Axe destroys obstacles and/or damages enemies 64 times, it cannot be used for the rest of the floor.
  • Added in Repentance The charges on Notched Axe cannot be refilled by means other than going to a new floor. This includes Batteries, Battery Bums, Added in Repentance15►4.5 Volt 4.5 Volt, Added in Afterbirth †15►Jumper Cables Jumper Cables, etc.

  • Added in Repentance 15►The Battery The Battery: Causes remaining charge from the previous floor to carry over to the next one.
  • Added in Repentance Bethany Bethany: Breaking Notched Axe and using a Soul Charge to activate it again will allow for a single use before immediately breaking. However, Soul Charges are not consumed in the process, allowing for infinite use of Notched Axe. This also works with Tainted Bethany Tainted Bethany's blood charges and is likely unintentional.

  • This item is a reference to Markus "Notch" Persson, the creator of Minecraft.
    • It resembles an Iron Pickaxe, which can be used to mine stones and ores.
    • Part of the new effect of this item in Repentance resembles the behavior of item durability in Minecraft.
    • The item durability being 64 could also a reference the max amount of copies you could hold in a slot for most items in Minecraft.
  • The item is also a reference to the Notched Pickaxe from The Elder Scrolls V: Skyrim, which itself was most likely also a reference to Notch.
  • This item got significantly buffed from the original Binding of Isaac, where it could not open up secret rooms and could only break 1 rock for every use, though it did only have a 1 room recharge time.
  • The "mineral" wisps that appear when using Book of Virtues with this item follow the same scheme as they do in Minecraft, giving the player black, silver, gold, blue, and red wisps, most likely corresponding to the Minecraft minerals coal, iron, gold, diamond, and redstone respectively.
