Next time you meet a dark shady character in that dimly lit alley, be sure you are prepared, not just to defend yourself but to belt a knuckle to their face. Designer Idan Arbel came up with the idea of combining both pepper spray and steel knuckles into one design called the Pepper Knuckle.
It is definitely a great way to get even with muggers who try to rob you of your hard earned money. I wouldn't mind one of these. Just make sure you don't get carried away with it.
