If you are looking for effective self-defense with extra reach, the Military / Police solid steel telescoping Tactical baton is for you.
This manually opened baton expands from 11" (when closed) out to 29" with just a flick of the wrist. It has a rubber covered handle for easy gripping and a heavy-duty nylon holster (with belt loop) for easy carrying.
The Military / Police Tactical baton retracts by vertically tapping the end firmly against a hard, non-giving surface.
