I assume everyone carries a Bic lighter at some time or another (or all the time)- tough to beat the simplicity when you need instant ignition. I carry one on a daily basis and thought it would be useful to have a reliable tinder source close by as well. I flattened a couple of tinder tabs and slid them under a section of inner tube. They are in there tight and not going anywhere. The inner tube serves double duty as a fire extender, works very well in this role. One of the drawbacks of a Bic is getting it accidently discharged- I've tried a couple of different size o-rings which didn't work, small zip tie which worked, but a pain to remove (and not going back on) and settled on a tied section of shock cord- can't discharge the lighter with it on and goes off/on easily.
