The Island, Merrick Biotech Security Baton

original movie prop

As clones Lincoln Six Echo and Jordan Two Delta rush to escape the artificial world in which they've been imprisoned, some of the security guards pursuing them wield these electrified shock batons.  As with the hook dark guns, these weapons are designed to incapacitate but not kill or permanently damage the product.

Metal baton with resin handle, electrical warning decals, and leather strap on a swivel clip.  Red button depresses but is nonfunctional; yellow button does not depress. A thin metal blade also extends from the end of the device (not seen in use onscreen).
