johnnysasakiIt's a military clip. I believe it's referred to as a "HK Snap Hook" in most places! It runs about $4 each, so that takes a big part of the cost! Any questions, I would prefer to keep in public so that anyone else with the same problem can reference the discussion, however if you have anything else you can email: info@handandsew.com
andyYes Thankyou! It's an awesome piece of hardware, it's meant to sit so that it's literally impossible for your keys to come out because of the spring gate! Fantastic one handed opening and all metal construction.
