Been doin' that for years. Back in my punk rock days (the first set, anyway... :lol: ) my original Zippo would need to be fed flints, and pickin' up expired Bics and other lighters usually yielded better flints than what you could buy in the packs. Make it a habit of gathering dead lighters and grab the flints, and you'll end up with more than you know what to do with--and wonder why people even buy them. :lol: That's part of the reason why my original prerequisites for a lighter at the start of this thread was a flint ignition. 8) Old habits die hard.
