UL fuel efficient cook system

Whenever I'm in the outdoors with a stove I have a backup lighter source such as a piezo or mini Bic, etc. I picked up a Piezo off of amazon, not sure the brand but works fine.

This shouldn't even be a rule, it should be a requisite, never go to the outdoors relying on one source of fire or ignition.
