 The middle 1950s saw two major innovations in slingshot manufacture, typified by the Wrist-Rocket which was produced by the Saunders Archery Co. of Columbus, Nebraska.The Wrist-Rocket was made from bent aluminum alloy rods that formed not only the handle and fork, but also a brace that extended backwards over the wrist, and provided support on the forearm to counter the torque of the bands.The Wrist-Rocket also used surgical rubber tubing rather than flat bands, attached to the backwards-facing fork ends by sliding the tubing ends over the tips of the forks, where it was held by friction or adhered with the addition of liquid rosin.
