Okay so in this world we have many self defense weapons, like the police, they have stun guns and pepper sprays. In the fist fighting world there are things called Brass Knuckles, which is made out of brass and can be held in your hand to be used as a knuckle protector while punching hard targets. Using a brass knuckle will also inflict a higher damage on your target.
But what we have here today is a Knuckle Blaster Stun Gun, is has incorporated the knuckle concept from the brass knuckles and has also put in a stun gun right in the middle in order to stun your target upon impact. The stunner is located on the middle and ring finger would be the stun gun which reportedly sends out a whopping 950,000 volts of electricity.
