FSAR-BLACK; Swedish FireSteel by Light My Fire; Army Model; While certainly not traditional, the modern fire stick is eminently practical. The Army model has a rod about 3/8" in diameter and 2 1/2" long. It comes packed on a lanyard with a striker. The assembly weights a bit over 1 1/2 ounces. Some folks prefer to keep a square corner in the back of their knife blade to serve as the scraper. It is said to last for about 12,000 uses.
