I've seen several examples over the last few years with firesteels and flints being wrapped with paracord in round crown sinnets, like those sold by TAD Gear, and I even have one made like that, that a friend sent me a couple of years ago.
So far I've tied a snake knot grip with 2.4mm cord on the longer one I bought, and the next shorter one had close to 10 feet of paracord tied as a lanyard around it, and a smaller lanyard tied around one with 1.4mm cord, which would also make a good sized zipper pull firesteel.

I usually have a lighter or matches on or near me, but should those fail and a firestarting need arise, a firesteel is a good backup, and don't forget some tinder to help get that fire going.
