Dull Razor is an unlockable activated item added in The Binding of Isaac: Afterbirth †.

Effect

• Hurts Isaac without taking away health, activating any items that trigger upon taking damage.

Notes

• As using the Dull Razor will grant invincibility frames like normal damage, this item can be used to enter Curse Rooms ( or use Blood Donation Machines and Devil Beggars) for free.

Interactions

For a full list of items that work with Dull Razor, see the list of damage triggered items. Note that any specific extra conditions the items may have for their activation still apply.

• Blanket/ Holy Mantle/ Wooden Cross: Absorbs the "hit", wasting both items.
  • Dull Razor ignores the shield, giving its normal effect without wasting the shield.
• Car Battery: Dull Razor activates twice, but "damage" is only dealt once, not triggering synergies a second time.
• Cone Head: Can block the "hit" Dull Razor inflicts, causing no effect.
• Crown of Light: Disables Crown of Light for the current room.
• Habit: Doesn't charge Dull Razor itself.
  • Habit + Schoolbag: The secondary item will be charged.
• Isaac's Heart: Completely nullifies the effect of Dull Razor.
• Purity: Will cancel the current effect of Purity, akin to taking regular damage.
• The Lost: "Damage" taken from Dull Razor does not kill The Lost, allowing him to make full use of Dull Razor.

Trivia

• The item works almost identically to the Voodoo Pin in Antibirth.
