The design for the special target restraining weapon was derived from the developmental discoveries associated with the hand cannon firearm. Each barrel has seven steel tubes, each of which has coiled wires with arrowheads at both ends. Due to 6 barrels being deployed in a normal set, it only takes a few stacks to stop even a fifteen-meter class Titan from moving and only 5 or 6 stacks to make it completely immobilized. Due to the exact design of the hooks, as the Titan regenerates, the hooks become lodged more securely.
This tool was deployed in order to apprehend and immobilize the Female Titan inside the Titan Forest, after Levi and his squad had led it into the trap. However, the host inside the Female Titan was able to escape in her human form by summoning a swarm of Titans with her scream to devour her Titan body.
