8 Inch Nails

8 Inch Nails is a passive item added in Afterbirth.

Effects

 * +1.5 Damage up.
 * Isaac's tears are replaced with nails, which have increased knockback.

Interactions

 * Piercing tears - Enemies will still receive some knockback as the tear goes through them.
 * Brimstone - Enemies will still receive a decent amount of knockback as they're hit by the beam.

Trivia

 * The item is a reference to the nails used to hang Jesus Christ up on the cross when he was crucified. The band Nine Inch Nails was named after these.
 * The visual effect on Isaac may also be a reference to a line in Eminem's "My Name Is", in which he says, "Wanna see me stick Nine Inch Nails through each one of my eyelids?". This line is also a reference to the aforementioned band.
