I think in this case the TSA agent was overreaching his authority. According to the current prohibited items list, there is no specific listing for ferrocerium rods or other fire starters, a standard cigarette lighter and standard pack of safety matches can be carried aboard.

There are also plenty of inconsistencies among the prohibited items list. I cannot carry a hatchet, knife or kubaton, but I can carry ice skates, 4" pointed metal scissors, and screwdrivers up to 7". Don't even get me started on everyday items that can be formed into improvised weapons.

In general I find the TSA people to appear unfriendly and undereducated/skilled for the task, but nevertheless they have always been efficient and accurate, and I've never been in a position to need to debate their decision. My main beef is the extra time and hassle of going through the security screening often counterbalances the convenience of flying versus other forms of transportation for shorter trips. My other beef is how airlines have capitalized on this by implementing checked luggage fees. I find myself driving much greater distances rather than flying, not just because of the hassle, but I also get to enjoy some of the highlights on the road.

Flying has become such a hassle that I cringe whenever its necessary. My philosophy is to carry everything I need for up to 3-days that is TSA-safe in one small duffel bag I can stuff under my seat and my Scottevest jacket that goes in the overhead, and bring enough Ambien to ensure I am completely out for the entire trip. Any questionable items go into my checked bag if I bring one, or gets shipped to my hotel via USPS Priority Mail a few days in advance and held for me to check-in. You can fit a lot of stuff into a flat-rate USPS Priority Mail box for between $5 and $15 each way, as opposed to the $20+ many airlines now charge for a checked bag. Other advantages are your stuff is insured for full value, delivery tracking is free if you buy the postage on-line, and best of all, no standing around playing carousel roulette hoping your luggage is taking the same trip as you.
