I keep the cotton balls with petroleum jelly on them in my fire kits (individually sandwiched between wax paper squares to reduce handling mess) with a lighter, matches, and ferro rod. I also put a small ziplock holding toothpicks in there. Break a few cheap ones up and you have dry tinder. I figure I should always have the easy option available if I can. I carry a bic in my pocket at all times too even though I have never smoked. I keep a couple small commercial fire started blocks in my hunting bag as another layer.
We used to carry paper matchbooks in a ziplock when I was a kid and Dad and I hunted. One hunt we had a mishap crossing a creek during mild but chilly weather. By the time we could get set up to start a fire, we could not strike the matches due to shivering. Luckily we could suck it up and finish the hike out. A lesson I have carried with me since.
