I just carry a mag bar that the army gives out to their troops.Seems to work pretty well if you can keep the shavings from blowing off into the wind.Then i have a firesteel gobspark which has to be the best combo i have had in awhile.Costs only $20 and i have had it for a year and its still got plenty of life left in it.
Then my favorite using old spent lighters i find beside the road and making them into fire strikers their free and just about anywhere beside the road.I have found 6 of em so far.
Also i make my own fire starters which is just charcoal fluid and paper towels lol.Works like a champ.I also carry a pretty neat old lighter made in Germany which doubles as a camp lighter since you can take it out of the lighter itself and use it to light things.Costs i think $10 on ebay and are by far better then the damn zippo's i have had.I do carry a zippo but rarely ever count on it for anything though.
You can build your own fire pistons for $5-11 at your local hardware store.Just takes alot of time to get them right.Oh and i also carry char cloth made from old denim jeans.That crap is simply amazing.
