On my last flight, I carried a keychain with a Streamlight Key-Mate flashlight, a BSA Hot Spark, and a small, aluminum capsule with a few pills and lots of cotton "packing" in it. This gives me a light, a spark, and some tinder (plus some headache relief).

I've gotten lots of close looks at the BSA striker, but since it has no edges and a rounded tip, it always passes muster.

I also carried a coarse diafold sharpener, a metal ball-point pen, and about 50 feet of paracord in my shoulder bag. I carried a 12-inch steel ruler in my carry-on luggage.

Before I fly again, I'm going to add some kevlar gloves to my travel kit.
