A device useful as a nightstick includes a generally linear long member and an attached short member. The short member can be curved or otherwise disposed so as to define a slot with a single open end. The device includes a handcuff clasp for closing the open end and to thereby define an enclosed portion of the slot between the long member and the short member. The handcuff clasp is moveable between an open position and a closed position. A trigger is provided proximate to the attachment point between the long member and the short member. Power means are also provided for closing the slot by rapidly moving the handcuff clasp to the closed position.
