I did some research on this a few years ago; my favorite story is about some flying explorers who landed in a remote spot, maybe New Guinea. As curious natives gathered around, one native rolled a cigarette, popped a light with the fire piston hanging around his neck, and proceeded to smoke. "Hey, that's cool, let me see that," said the pilot. "Here's how I do it." Demonstrated his Zippo. "Hey, that's cool," said the native. So they traded.
But while the pilot ended up with a lighter that would work the rest of his life, by the time the native showed his Zippo to all his friends, it would be out of fuel or spark, and totally useless. So who had the better lighter? Steve
