There was a day, many years ago, when someone decided to adopt the standard climbing carabiner as a keychain. Practically, it made a lot of sense. But not long after, belt loops everywhere had the simple device hanging from them. If you’re looking for something a little sharper that isn’t as ubiquitous, consider the Cotter Keychain, a U-shaped brass and stainless steel keychain that’s crafted by Harold, a New York-based design team, to be a fresher way to tote some keys. Made in the USA, the keychain features a top pin that is cold forged to allow it to slide in smoothly but never separate. It’s time to leave the carabiners with your climbing gear.
