Thanks for the help. I have (hopefully) learned to ask the experts then buy, not the reverse. Most of us have learned many lessons (especially with regard to our respective professions) most of which I cannot financially afford to make for myself (plus life is too short). Anyways I think I am going to get a key-ring style and just clip it to my EDC pack. My keys are already way too big to add anything else and maintain social decorum. Again thanks for the excellent info.
