I make and sell primitive fire starters mostly flint and steel sets. Boy scouts are probably my largest customer base but so many others like starting fires this way using a piece of steel and a rock and maybe using char cloth or chaga to catch that spark. Make a birds like nest of natural fibers such as manila rope or jute twine, maybe dried grass or cedar bark, dried sage. What a great way to compliment your outdoor adventure. I'm also selling mischmetal rods also called ferrocerium or ferrorods or firesteels. Thank you for looking!
