I think the best firestart for the money is the six inch long 1/2 inch diameter ferrocerium rod. These can be purchased from various dealers and are one of the best survival kit items you can buy. Smaller versions are the swedish fire steel and the Doan firestarter. The Doan has a small rod attached to a magnesium bar. The only issue I have ever had with the large one is loss. Otherwise it has lasted for years. Wet, dry, cold, hot, summer, winter, you name it, it will work in any environment.
