Used to carry BICs until I realized they no longer worked well for me when my hands were cold and wet. Loss of tactile sensation and degraded muscle control - when cold and wet - made me turn against them.
I've got a couple of other lighters - a Zippo and a butane cigar lighter. Carry one or the other as back up but have yet to need either. Swedish fire steel and vaseline-cotton balls have been working the first time.
Think I may carry a road flare next time I go out. Just to try.
