A buddy and I were hunting one fine sunny day last year during black powder season, and he wanted to smoke a pipe after lunch. Neither of us brought a lighter or matches (I was just indulging in chaw myself). But then I remembered I had a magnifying glass attached to my compass. So... we gathered up a bunch of dry grass and twigs, emptied a powder charge into the middle of it, and ignited it with the glass. Got a little fire going, problem solved!
