Next down the list goes Bics and bic clones.

Then matches in dry sealed containers, then sparkers like the Doan or Swedish fire steel.

Flint and steel, fire drills, magnifying glasses, plow sticks and all the rest are all extreme measures.
Nice to know just in case you have nothing better, but not to be preferred over functional lighters.
