You are driving a jeep through the woodlands of your state when all of a sudden your jeep breaks down. When you pop the hood you try working on the problem and you can't fix it. So you then look at your cellphone signal to realize you are not in range of a cell tower. Not prepared for the couple day hike you start making your way through the woodlands back to the main road. Of course at nights you might want to a way to warm up some food that you had stored in the back of the truck. What better thing to have is a keychain with a firestarter on it. That way you do not have to worry about spending hours finding flint to start a fire.
