Longbow,<br><br>Also try your local Boy Scouts Supplier. Their "Hot Spark" is small and inexpensive. I got a handful to spread througout my gear. Each was $2. They have a small diameter "flint" about 1" long with a good plastic finger-grip handle.
BSA Hot Spark <br><br>Slip one on your key chain covered with some nylon tubing from Home Depot, add one to each PSK and you are set. These do not produce the mass of sparks you get from the larger WSI, BlastMatch types but more than adequate if you practice and also carry some tinder (cotton/vaseline). My key chain fire kit consists of one BSA Hot Spark and a Bison capsule with tinder.
