Fire can prevent hypothermia, purify water, and cook food... a good fire starter is an essential part of your emergency preparedness gear. Ours is a tough, water resistant magnesium ferrocium fire starter rod, plastic emergency whistle, and steel screwdriver/bottle opener/ruler. It won't run out of battery or oil, doesn't get ruined if it gets wet, and will last practically forever properly stored with the rest of your survival gear.
