On several threads I have seen what I can only describe as "Pocket Hangers", a small metal piece bent around to hang off of a pocket, usually attached by short cord to a knife, SAK or MT. These appear to act as a substitute to a clip. Can someone point me to a reference on these? Where to acquire? How well they work? I'm thinking added to a Juice S2 this would be a nice pocket carry if they are feasible. Much thanks!
