Knife Center’s Self Defense Money Clip [$13] is the wallet that just might come in handy if you find yourself in a bar like the Boar’s Nest down in  Hazard County. This simple device has an aluminum front plus a clip for your moolah, both with a hole through their center to slip over and through a finger, and a general shape that’s more than a little reminiscent of brass  knuckles. While I’m not exactly sure how much damage this little piece of metal could inflict, it’s bound to be better than just using your bare knuckles.
