For those not familiar with the uses of a firesteel, it's basically a ferrocerium rod (in this case, with a Blister Ooline handle, and red paracord lanyard) which can be scraped with a squared off or sharp piece of carbon steel (square back of a knife or the blade if you don't mind potentially ruining your cutlery).
Think of a flint and stone but somewhat modernized and instead of getting one little spark, there's a shower of them.
