I have a
Zippo Blu that is flint and butane. All made in USA, 100% Zippo, and no insert or any of that stuff. It was a gift set that came with butane, extra flints and the lighter.
On the traditional zippo question, I've watched old-timers put kerosene in their zippos. I worked at a gas station when I was a kid and they'd go to the pump and get the few drips that were in the nozzle. I thought for years that was how you were
supposed to fill a zippo.
