Getting hit by somebody wearing a knuckle duster is going to hurt at the best of times, so I dread to think what one that packs a 950,000 volt punch will feel like.

The Knuckle Blaster Stun Gun is intended as a self defence device for people who jog in dodgy areas (and if it’s a really really bad area you could always wear one of these on each hand as well as the defensive jacket).

Before shocking any potential muggers you should probably ask them if they have a pace maker, then again nah, just knee them and follow up with 950,000 volts to their face.

You can get the Knuckle Blaster Stun Gun via Amazon for $44.99.
