I have read so many of the "TSA-Friendly Kit" threads and have come to realize that you can actually make a pretty effective kit and still be TSA-friendly. It just takes a lot of a creativity and little extra skill. By creativity I mean things coming up with alternatives to edged tools like implements for creating an edged tool in the field (blunt file and blunt piece of metal for example). By added skill I mean things like knowing how to start a fire with TSA-friendly materials (steel wool and a battery for example). Your kit may not be as capable and easily usable as the one you take camping which includes a lighter, matches, sparklite, firesteel, a 6" fixed blade and a 4" folder, but it will still be miles ahead of having not kit at all.
