Abstract: An impact weapon having an elongated body with an undulated, continuous, outer surface which extends along an axis. First and second end portions are connected to opposite ends of the elongated body. A first depression zone is formed on the continuous undulated outer surface adjacent the first end portion while a second depression zone is formed on the undulated continuous outer surface near the second end portion. The first and second depression zones include at least first and second depressions respectively that are angularly separated from one another about the axis by approximately ninety degrees.
