The Binding of Isaac - Mom's Knife

When on the ground Mom's Knife is a big kitchen knife, after Isaac picks it up he gains mom's big polkadot dress along with replacing his tears with the knife. Instead of tears you now throw the knife to hurt enemies, the longer you charge up your knife the shot the farther it will go. The knife is able to pass through enemies and over holes. This collectible is one of the most high damaging in the game only behind Epic Fetus, the most damage is caused by the tip of the blade rather then the body. Mom's Knife is able to synergies with other items that effect tear effects making it even more dangerous. The item can also be used in close range by walking into a enemy with the knife pointing at them to stab them. This item is found in Devil Rooms and Treasure Rooms. It is unlocked by clearing Sheol by beating Saten with Isaac.
