Regular fire drills require tinder in reality as well, so tinder is most likely implied instead. But if you go for tinder-fueled path, perhaps make it a full-on tinderbox instead of just the flint and steel?
By being a copy of regular lighter with different attributes, of course, unlike the annoying-toggle-it-on of the refillable one! And balanced via rarity of the requisite ferrocerium, and perhaps high survival/mechanics (to be consciously aware of “fuel-soaked cotton burns longer because evaporating fuel burns up first before cotton starts to char” thing) skill requirement. Or being in some obscure books.
