I carry:

A fero rod
REI's storm proof matches
A few matches for stove starting and so on.
A small Bic lighter
Vaseline and cotton balls, preloaded and packed in a vial

This takes up little room and is very light weight.

Completed a SAR mission in June and located two hikers on the PCT
that were soaked completely through, had only strike anywhere matches and just about zero training on fire building. Training might be just as important as the gear.
