Pika:
I was not aware that there are two Bic lighters, standard and Mini.
I see now that one weighs 0.7 ounces and the other 0.4, that is a savings of 0.3 ounces. However apparently the standard one I carry has some fuel missing because it weighs 0.5 ounces on my scale (plus or minus 0.1 accuracy, I suppose).
RE; fire starters. The reason, I was taught, you carry fire starters is not for building the usual campfire, but rather for emergencies. However emergency fires can be more work than they are worth sometimes. Some say stay dry, save your energy, forget the fire.
