The Swedish Fire Steel Army model is a must have for any outdoorsman, survivalist, camper, hunter or anyone that might need to build a fire in the worst of conditions These are great and can be a real life saver. The Army Model is the “full size” FireSteel that fits many of the current knife sheaths that feature a pocket for the FireSteels. They’ll work wet and throw a 5500 degree farenheit spark. Great to ignite the fuel in a camping stove in rain or snow. The perfect size to keep in the glove box, tackle box, back pack or pocket. Don’t go outdoors without one!!!
