Unlock Method
The Razor Defeat Satan as Eve Eve

Razor Blade is an unlockable activated item.

Effect[edit | edit source]

  • On use, takes a full heart of health and grants +1.2 damage for the current room.

Notes[edit | edit source]

  • Added in Afterbirth Eve starts with this item after unlocking it and donating 439 coins to the Greed Machine.
    • Both conditions must be met for Eve to hold it; donating 439 coins before defeating Satan with Eve will wrongly state on Eve's profile on the Character Selection Screen that she has it equipped.
  • If Isaac doesn't have a full Red Heart or a filled Bone Heart, then Soul, Black, and empty Bone Hearts are taken instead.
  • The effect stacks with itself and Red Patch Red Patch, which provides a similar benefit.
  • Using this item does not affect Devil or Angel room chances.
  • Using this item as The Lost will result in death.
  • When picked up, Isaac's tears turn red, though this change is purely cosmetic.
    • Using this item in the Greed mode Ultra Greed boss room will result in Isaac losing 2-4 coins and dropping 1-3 pennies on the floor similar to being hit by any of the greed enemies.
