The guys that brought us the Keybrid Key have a new product due out this Fall. It’s the Carabiner Key and it’s exactly what it sounds like. It’s a key with a carabiner clip built into the top for easy attachment to a belt loop, backpack loop, keychain, etc. The Carabiner Key comes as a blank. Just take it to almost any shop that sells keys and they can grind the key for you. This product will be available via Amron Experimental in the Fall for $7-$10 each.
