Our good friend Joerg Sprave—the rubber-artilleried mastermind—has been building crazier and crazier weaponry, so it makes perfect sense that he'd dip into the definitionally insane world of Japanese anime for inspiration.

In addition to being used as a slingshot, it can also be used as a spear or javelin. And if you're not familiar with One Piece, here is the American rap song intro to the show. [Slingshot Channel]
