Javelin with 125 Lumens of blinding constant on or pulsing light, to blind your opponent, and a glass break/self defense bezel, if you dig that bezel into someones face, neck, ear, eyeball, etc, you will stop their attack dead in its tracks. You press the end of the bezel firmly against their skin, and then as you push in harder you use a twisting motion to twist and tear flesh at the same time.
It has a legitimate purpose in your vehicle, its an emergency light in case of a road hazard or for changing a tire or other motor vehicle trouble. I was keeping a 4-D Battery maglight in my car until I got this.
Of course, carrying a firearm is always the most preferrable weapon for self-defense, so as not to accidentally bring a flashlight to a gun fight, but unfortunately in the peoples republic of New Jersey (PRNJ), self-defense is a crime, and we have to allow lawless thugs to assault us like a lion stalking a f**king Carabou.
