Instead of having a firestarting flint strapped to your multitool, why not add a multitool to your lighter? The LighterBro (as millennial as that name sounds) is a simple sleeve for your lighter, with a few tricks up its sleeve.
The stainless steel sleeve acts as a housing for most standard lighters (not those fancy flip ones) and gives it way more than firepower. I’m talking a razor sharp knife (tough enough to cut paracords), a scissor, a bottle-opener, and even a micro-screwdriver. Carry it around as you would a regular lighter, since the sleeve is super-slim and rather indistinguishable in the pocket, or strap it to your keychain via the keyring attachment on the LighterBro and you have an instant outdoor (and even indoor, honestly) life-saver!
