Considering that we live in a day and age where virtually everything is keyless, it seems for traveling enthusiasts like ourselves there's still a lot of keys hanging around. Whether it it's a combination of keys for your house, or the keys that unlock all of the accessories you've bolted to your vehicle, you end up with this bulging key ring that never quite works right. There's somethings in life that are simple and should be left like that, but god forbid you need to remove a key from a keychain, to say the least it's not fun. Luckily there's a country called Sweden, and within that country exists a group of people who design things very well, like the FREEKey System ($6.49) which allows you to simply, and easily remove keys at will—without destroying your nails and causing general frustration. A simple pinch of the key ring and you'll be able to remove anything your heart desires. Don't feel like bringing the keys to your brothers house, your motorcycle, and your boat into the desert when you go exploring? It's now actually possible to remove those keys with the FREEKey.
Hat tip to Gianni for the suggestion.
