Good old Joerg Sprave is back with another deadly and scary slingshot to share with us all. If ever a geek needed to make a cameo in The Walking Dead, this is the guy. His inventions would be the perfect weapons once you run out of bullets during the Zombie Apocalypse. The last time I talked about Sprave he was showing off his machete slingshot. This time around, he has a new slingshot that is flinging blades from a circular saw.
