When a pocket knife is too bulky and a Swiss Army Knife is simply too useful, the better alternative would be this cool new Boker Credit Card Knife. This uniquely slim, lightweight and compact blade, designed by Massachusetts knifemaker John Kubasek, easily slips discretely into your wallet like a credit card, can be carried via removable pocket clip on your shirt or worn on a ball chain around your neck. It weighs only 1.1 oz and features a titanium liner, a high performance 440C stainless steel blade and a reliable and sturdy frame lock mechanism. It's a handy little tool to have, but don't accidentally try to pay for things with it, because it may send the wrong message.
