Technically the Spark Lighter and Tinder from the Ritter kit could be considered a lighter without fuel, OK in checked baggage but not carry on. Trust me, the folks who work screening for the TSA are not the sharpest spoons in the drawer, and it is not worth arguing the point with them. However, my kit passes muster for checked baggage.

A personal survival kit specifically designed to be TSA/airline friendly for carry on would make a great subject for a new thread. You could at least have safety matches in it.
