This is THE BEST dog tag survival kit! Custom made in the USA by Alex Shunnarah, this ARS dog tag knife slides into the molded case to contain a compass and ferro rod with room for tinder. The blade is sharpened 440C, polished to double as an emergency mirror. It comes with a chain, but the blade could also be retained by slipping paracord through the hole as well. Comes with a fire starter, compass, chain as well as a protective case. Throw it in your backpack, car, or neck and forget about it until you realize you need it! Alex Shunnarah does amazing work!
