This band is made with 15? of black 550 paracord, the clasp toggle is made of flint, the tag is a "Don't Tread on Me" plastic plate with a mettle striker plate under it and is attached with jute twine.
To use the band you would first remove the jute string and stainless steel tag (striker), take the jute twine and fluff in to a birds nest, take the flint (clasp) in one hand and the striker in the other, scrape the striker against the flint while resting in the jute twine, you will create a spark that will light the jute. Then add twigs to get the fire going, eventually wood. You can also use the back of a knife to strike against the flint if you have other means of tinder to start the fire without breaking down the band.
Recharging the band, take any medium needle with eye hole, then lace jute back in to band with the striker for the next time.
Uses: Fire starting, cordage to tie down, boil water, cook food, or just to keep warm, there are many uses, the list goes on.
