Leave No Zombies Walking: Brain-Slicing Arrowheads

Admittedly, zombies are harder to kill. The fact that they're after your brains gives you more incentive to kill them. But the fact that they're already dead and aren't afraid of being killed again works against you, because you'd obviously want to stay alive and keep your brains intact after your encounter with them.

A surefire zombie killer? This brain-slicing arrowhead. The goal is to shoot it at a zombie's head. Upon contact, two small knives will flip out from the arrowhead, slicing through the zombies brains and making sure it's dead--for good.

The arrow was made by Joerg Sprave. Awesome stuff.
