#114Mom's Knife"Stab stab stab"Passive item
Replaces Isaac's tears with a knife that pierces through enemies and can travel through obstacles.

Holding down the fire button increases the knife's range and power.

The knife deals 2x Isaac's damage 20 times per second while held, and 6x Isaac's damage at about 1/3 full charge. Damage quickly drops to 2x Isaac's damage when returning regardless of charge. Further charging only increases the maximum range.

Can be fired diagonally by holding down 2 firing buttons at once.

This item contributes towards the Yes Mother? transformation. Collecting 3 items from this set will give Isaac a stationary knife that trails behind him and deals 2x contact damage.
Unlock: Defeat Satan as Isaac.
