Sorry Hurley52, you're wrong:
"All lighters are prohibited as carry-on items. Lighters without fuel are permitted in checked baggage. Lighters with fuel are prohibited in checked baggage, unless they adhere to DOT exemptions, which allow up to two fueled lighters if properly enclosed in a DOT approved case."

When I fly commercial, I carry the Ritter PSK w/o scalpel,a HeatSheet, a travel FAK, Doug's Photon light, and a Surefire.
