During the cold war – and even before – it was pretty common practice for pilots and spies to carry around tools hidden within normal everyday objects. Everything from tiny cameras hidden within necklace charms to suicide pills hidden inside of tooth caps were employed. But, just because the Cold War is over, it doesn’t mean those cleverly disguised things have to go entirely by the wayside. You can, in fact, incorporate it into your everyday carry.
One way to do that is by carrying around the Air Force Coin Knife. Minted from nickel and featuring the official logo of the United States Air Force (as well as a commemorative image on the reverse side), this coin actually hides away a trio of tools you might normally find in, say, a Swiss Army Knife. The scissors, small blade, and file that fold discreetly into the body of the coin, which are made from stainless steel, are handy whether you need to get yourself out of restraints or you just need to trim your nails. And, once you’re done, they hideaway once more and your captors or any onlookers will be none the wiser. The Air Force Coin Knife retails for $43. [Purchase]
