What is your favorite firestarter? In my BOB, I keep a magnesium stick and about a hundred waterproof matches, but everyday I carry my favorite: The Hot-Spark. I got it from a Boy Scout's website for around $1.40, and I put it on a chain to wear it around my neck at all times. The striker (a rough piece of metal) loses its effectiveness quickly, so I just keep the flint on the necklace and use the reamer on my Swiss Army knife as a striker (since I am NEVER without my knife). The reamer helps make a bigger spark, and I've had no problems starting a fire.
