I always carry a zippo camping. Once or twice I've found I forgot to refuel it, and once I've soaked it. But, it's survived, and functioned after, many a rainstorm that would have killed a bix of matches, and has lit things for me at temperatures so cold that using matches would have been difficult, and a butane lighter impossible.
I wouldn't call it my survival lighter, or my sole fire starter, but it is the first one I reach for, and with few exceptions, the last.
