FSMN-ORANGE; Swedish FireSteel by Light My Fire Mini Model; for those truly concerned with weight and bulk, the Mini weighs about a half an ounce, complete with lanyard and striker. It's rated at 1,500 uses. Without the striker it's just over a quarter ounce, and is a bit under 3" long. This is about the size of a car key, and it would ride nicely on your key chain.
