Abstract
Abstract A self-defense/attack device comprises a rigid, tubular body having a blunt tip at one end that is adapted to deliver lethal/non-lethal blows to the chest or other regions of a human body. Joined to the tubular body at a substantially right angle to the longitudinal axis of the body and closer to the end opposite the blunt tip is a rigid projection shorter in length and smaller in circumference than the body itself. The projection terminates in a rounded blunt tip that can also deliver lethal/non-lethal blows to an attacker.
