Created by Personal Security Unlimited, makers of the ever-controversial Psionic blocker. This baseball-sized device features six short, bluish metallic cylinders emerging in all directions out of an eyeball-sized rubber ball, with a single-use button that releases a powerful psi blocker-like blast, and a switch for five and thirty second timers, as well as a contact option for the grenade itself. The psi grenade quickly and efficiently neutralizes psis, knocking them unconscious so that they can be subdued.
