I'm carrying the butane soldering iron when car camping and in my urban GHB. It has quite large gas tank compared to the bic or other torch lighters for smokers, the reliable spark wheel ignition, wide range of pressure control, and several interchangeable tips for different work - very versatile. The high temp torch flame helps to ignite almost anything without much preparation i.e. in a hurry. It will dry wet kindling almost instantly, ignite raw BBQ charcoal in several seconds, e.t.c. And of course you can solder some electrical wires or metal parts if the need arises (with a piece of rosin core). And it is the size and shape of a large marker - easier for reaching kindling's center in a pile, compared to bic and others. I like it very much.
