Matches, sparklite, tinder in one.<br>If you are chained to a specific med i.e. nitroglycerine carry it.<br><br>I'm currently looking for a way to carry Potable Aqua in one capsule.<br><br>I do a lot of international travel and find a social-security card and photo-copy of my Drivers License to be a life-saver in case I get mugged.<br><br>As far as extra cash try folding the bills in half and then rolling them up. In one such kit I was able to fit 10 Dimes, Emergency data card, ssn card, D.L. copy, 10 twenties, and spark-lite with 5 tinders into one capsule. I had to give it up though because the attachement ring wasn't very secure.<br><br>On the note of Key Chains I am redoing mine completely and I am trying to figure a way to wrap a BCB wire saw so that it will function as one ring with several smaller split rings attached with other survival gear. Any suggestions will be greatly appreciated.
