Could this be a post-Apocolyptic survival weapon?
Toyland has this to say:
As much as we’d love for slingshot-designer Joerg Sprave to visit the US on a publicity tour, it’s creations like this—a Nerf blaster made lethal using razor-sharp scalpel blades—that will probably result in him being barred entry to the country.
In addition to his countless original creations, Joerg has a long track recordof turning seemingly innocuous objects into frighteningly dangerous improvised weapons. And while out of the box this Nerf blaster is safe for kids, it doesn’t take long for Sprave to turn it into something that even adults probably shouldn’t be playing with.
Don’t try this at home… Unless zombies attack and the Government has your weapons!
