I wasn't familiar with Joerg Sprave and his Slingshot Channel, but thanks to Perry Michael Simon over at The Nerdist, I am now! Joerg is a Slingshot enthusiast, and took it upon himself to build the ultimate close range, hand to hand zombie weapon. It is a full fledged slingshot with counter balance. It is a full weighted hammer, with both a blunt striking area and a spike. And since we all know that getting sharp instruments stuck in the skull of an oncoming zombie, Joerg devised an skull ejector bar for the weapon as well!
If all that wasn't enough? It even has a handy dandy carrying handle!
