No butane lighters for me. I've never seen a reliable one. So what's the point of having one for emergency use?

Firesteel for reliability. Two Bics for convenience. Waterproofed matches and a small fresnel lens for additional backup. Vasoline cotton and commercial prepared tinder. "Can't blow 'em out" trick birthday candles for the windproof needs. I've never had to actually use those birthday candles, but that's my windproof plan (hope it works!)
