No offense, but good luck carrying your kit on a plane with the lighter, Spark-lite tinder, and wire saw. If you have done this post-9/11 I'd like to hear about it. The last time I flew about the only thing I carried on board was a small flashlight.

TSA Permitted and Prohibited Items

I have a pretty small minimal kit with the following: Spark-lite, Spark-lite tinder, a couple of MP1 tabs, band-aids, button compass, flat whistle, signal mirror, tweezers, and Photon keychain light. This is all housed in a tiny waterproof Witz container (a la SgtMike88Ret) with a short run of paracord for a lanyard. In addition at least a Leatherman or quality folder would be carried as well.

But I sure wouldn't try to live on that kit. It's more like an absolute last resort.
