There are quite a few things that don’t need an explanation of purpose or a rationalization for purchase. Things like: beer, books about butts, gadgets to use while pretending to work and knives. We don’t really need to explain to you why a surgical stainless steel credit card that folds into a knife is the best invention ever, but we’re going to anyways. It can act as the last line of defense between you and the ruthless bums in the city. It’s capable of trimming loose threads. It can cut steak or cheese. It could potentially save your life if your arm ever gets caught in a bolder. It’s also black, goes anywhere but TSA checkpoints and only costs $23. It’s bladed perfection that you can carry in your wallet. Warning – we’ve received quite a few emails telling us that this retailer is not fulfilling orders. Order at your own risk.
