  • Hand held defensive weapon
    Patent number: 4034982
    Abstract: The principal element of the weapon is an elongated shaft sized to be grasped within the defender's fist and to extend beyond both sides of the hand. A finger ring is pivotally mounted on the shaft and is sized to be received over the defender's middle finger. The pivot point is offset from the longitudinal center of the shaft so that the shaft rotates under the influence of gravity, and the defender's hand movements, between cross-palm and finger aligned positions.
