Madison Supply, Waterproof Magnesium Fire Starter, with tinder box and 3 ferrocerium rods (black) Magnesium ferrocerium rod, plus 2 refills - great value, lasts 3x longer than competing flint and steel type strikers. Also includes: a steel striker, a small compass and unsoaked cotton tinder. (Left unsoaked so customers can choose their preferred flammable. Just add a couple drops to the tinder compartment, or roll the tinder in vaseline - our method of choice due to the ease of use and reliable flammability.) Waterproof - machined out of aircraft aluminum with rubber gaskets to seal out moisture, will light a fire in tough weather conditions. Compact and easy to take along - has a loop to hang on keys or backpack, or throw it in your glove box. To provide a better grip when striking- after you unscrew the ferrocerium rod and the striker, spin the rod around 180 degrees and thread it back onto the case (see photo).
