Schnelle Engineering fabricates far more keychain pocket tools than will ever fit in your pocket, but if you can pick just one of the company's curiously-shaped designs, you'll be golden and FAA-compliant for cracking open your cold ones. Or digging rocks out of your shoes. Or tightening the leaky faucet in newly-single 402's unit on your way up from the lobby.
From a dual standard/twist-off bottle opener modeled after the sun to a fireman's ladder pry tool with integral top popper, all Schnelles are made of aerospace-grade stainless steel and boast EDC aesthetics that niftily distinguish them from all the other Toms, Dicks, and Gerbers. In addition to bottle openers, the keychain tools are available with wrenches, screwdrivers, and box openers.
