I've tried many different brands of hand held strikers. All work fine at home (4k feet) but won't work when camping at 6k or higher. I have yet to find one that works at high altitude.

Does ANYONE make a good old reliable flint striker anymore other than the torch type striker? Those are too hard to get under a stove burner.
