ONE-HANDED OPERATION: Not only is the nanoSPARK easy to use with a little practice, but it is also operable with one hand in the event of an injury. REPLACEABLE FLINT: The flint is easily replaceable by removing the brass screw inside the tinder capsule. Up to 5 extra flints can be stored inside the tinder capsule. TINDER STORAGE: Unscrew the body from the flint holder to reveal a quickLIGHT tab. Fluff the tab with a knife or pull apart with your fingers and it’ll catch on the first spark! The lanyard slot can also be paired with a tinderZIP zipper pull for extra tinder.
