Skateboards make really good weapons, because you can slash with a curb sharpened edge, swing the board like a bat or leave a dent in a forehead with cast metal trucks.
But Joerg Sprave of The Slingshot Channel didn't do much skating when he was younger, because he was too busy cutting stuff up and turning it into weapons in his workshop.
In this episode Joerg cuts up a skateboard to create a mighty powerful, pulley based slingshot that can shoot a 60mm lead ball straight through particle board, thereby making it the ultimate way to carck heads open with a skateboard.
