I carry a Gobspark Armageddon steel with scraper, always.
http://firesteel.com/gobspark-armageddon-firesteel/And I have a couple of Altoid tin "firestarter kits" with the light my fire steels along with some Vaseline cotton balls, birch bark, fatwood slivers, etc.
But rarely do I start campfires and if I do, I'll likely use a fire steel just for "practice". I mostly carry the steels for the unlikely event of actually needing a fire. Just easier than carrying matches and will light a Vaseline cotton ball just as fast.
All kidding aside, I usually use a Bic lighter to light my stove...which is about the only thing I "light" when on a backpack hunt, and usually have one on my person.
And though I've never had a failure of a Bic it could fail and thus I carry the firesteels. I don't dink around with matches much since finding true strike anywhere matches is difficult. And you can't fly with them.
