How you pack for the outdoors depends on how you intend to spend your time exploring nature. Packing light seems to be a common goal of campers, hikers and survivalists. Most also agree that it’s wise to have a compact way to cook a meal, boil water, keep warm, and create light that will keep away animals like wolves. For all of these things you need a reliable source of long-lasting fire, but most of us don’t want to carry flammable liquids or gels in our packs. I will show you a safe alternative: a pocket-sized piece of survival gear that you will quickly start to regard as an essential item to pack for your next adventure — no matter what it is.
