We’re not sure who the first person was to use a carabiner as a key chain, but if he/she could have profited off of all the people who borrowed the idea, they’d be rolling in Scrooge McDuck type money. For as smart as that idea was, there are plenty of people who keep any carabiners they own for climbing and the like. For a stylish key holding option, there’s The Key Square. Cut and machined from a solid piece of stainless steel, The Key Square is a key chain and bottle opener that slips right onto your belt loop. Unlike a carabiner, it’s also small enough to fit in your pocket comfortably if that is your preferred method of key transportation. Made in the USA and hand-finished, The Key Square is solid option to holster your keys and crack your beers.
