I'm kind of supprised nobody mentioned the good old Zippo lighter yet. In these fast-paced days it seems the Zippo is going out of style, replaced by the newer propane torch lighters. That's all well and good, the propane models put out a hot flame, but how easy is it to get (usable, refillable for the lighter) propane in an emergency ? The original Zippo hasn't changed in the basic design since 1933. The original fuel was Naptha, which can be had for $7 a quart at the local hardware store. I've heard that diesel fuel or kerosene will work in a pinch. I rummaged around the house and found all of my old lighters. No, I do not smoke, but I used to carry a lighter on me all the time. I just fell out of practice. So I thought it was time to refurbish the lighters so I bought 4 sets of wicks and 4 sets of flints. Amazingly, the lighters didn't need any wicks as the ones that were in them just needed trimmed a half inch. I replaced the all the short flints with new ones. Then I just filled them all up with Naptha and tested them out. Super simple setup.
