windproof ligther

I think it's VERY important to have a 'quick and easy' method to start a fire and a 'last resort never ending' way to start a fire.
Quick easy = ligther or match
Never ending but harder to use = firesteel



A blast match is nice but heavy and when testing I broke the striker off. I wouldn't rely on one but you could use the steel inside it with a knife of scraper.
