I'm slow to respond, Bobson, but I generally carry a butane lighter. Just a Bic or Scripto disposable, two if one is getting low. Other things in the car (including flares). If I'm going into the hills, I'll go with multiple sources, add in waterproof matches, fuel tabs, etc. Not long after I got my straight handled Busse Steelheart II (ordered in 1999, received in 2000), I had a custom sheath made, including a pocket. The pocket carries a firestarter I picked up at a gun show: Rectangle of oily reddish brown wood (I forget the type), a 3/8" rod of magnesium and 3/8" rod of "flint" glued on one side, a coin shaped striker that is a plastic disc holding what appears to be a piece of carbide (marked E-Z Way Sharpener, so I guess it has two functions) attached to the wood by a small thong. Shave the wood, shave the magnesium, then make a shower of sparks. I usually carry something like trioxane or similar fuel tabs, too. Almost never use the blade of my 30 year old Bowen Survivor belt buckle (in its fourth or fifth belt, this time a custom Beltster), I use the cap lifter more often, but constantly use my Al Mar SERE2000 and my Ed Caffrey EDK-1 neck knife, and the blades on my Leatherman Wave fairly often. Just can't imagine not having a knife handy. Shortly after dropping a small pistol and tactical level flashlight into my bathrobe, I realized I needed at least a pocketknife in that. One uses a knife constantly around the house.
