I know a lot of guys are very content with Zippos and don't detect any taste. To be honest, maybe what I get isn't really taste but smell. But they're pretty closely related. So the sensation for me is that I'm tasting a hydrocarbon.
It's a shame, because it is the classic American lighter, they are super wind resistant, the flame temp is perfect for pipes, and I have the one my Dad carried in the war. I'd love to use it, but just cannot.
