What do you carry on your keyring. May sound trivial, but, this arrangement has not changed for me in over 20 years, one item goes back to my military days. Can you identify it, an indispensable item for sure. I have carried that since...omg its been that long.:ignore: And no Naekid, not the two jeep keys. In pocket, lighter/flashlight/mirror combo, and pocket knife. Clipped on belt with small carabiner, 3" folding knife, and high power LED flashlight. And yes I check them for functionality regularly, batteries, butane and blade sharpness. P-38 P-38 Can Opener - The Armys Greatest Invention.
