Dual compartment carabiner with one hinged piece keeps your things separate, or use one end to clip onto a belt loop. If you don't mind people stopping you to talk about your keys, this is the piece for you. Call it portable popularity, if you will. Like everything from The James Brand, this is an exercise in lightweight, sturdy, precision engineering. The action of the carabiner is like crack for your OCD. It's machined from a single piece of metal, and you just wait to see how the thing patinas with use. It's an heirloom. Oh yeah, it's also got that little nifty thumb hold thing, that is (ta-dah!) also a bottle opener. Enjoy your drinks in moderation, but your James Brand in hearty excess. The James Brand makes beautiful objects that not only you will love, but it will love you back (figuratively speaking, of course).
