Checking out with my purchases at the drug store last week, I glanced over the selection of mints and chewing gum. Next to the regular-sized tins of Altoids was something called "Altoids smalls."
The tiny cinnamon mints appealed to me. The tiny stamped-metal package inspired me even more. Unable to resist, I bought one.
Fifty mints later, left with an empty tin measuring 2-3/8 by 1-5/8 by 5/8 inches, I set about building an ultra-compact (and yet effective) fire kit that'd nest inside.
Some of the contents were no-brainers: an eighth-inch firesteel blank two inches long; a four-inch stick of fatwood, quartered to fit; a length of jute twine; and a piece of bicycle inner tube (a.k.a. the multi-purpose "Ranger Band").
I struggled a bit with what to use to strike the little firesteel, ultimately choosing a knockoff of the Victorinox Classic, a freebie that I had hanging around. If I'd had an old LMF striker or a hacksaw blade to cut down I might've done that -- smaller, lighter and arguably stouter -- but this knife will do in a pinch.
It occurs to me that the el cheapo pocketknife can be used to shave the fatwood, too, and make small fuzz sticks. It was a tight fit for the Altoids mini-tin, so I filed-off its key-ring tab to make it a bit easier to stow.
With a firesteel and striker, jute, fatwood and yes, rubber -- that Ranger Band not only keeps the tin shut, a chunk of it also will burn for quite a while -- I've got a useful pocket-sized fire kit. It may not be ideal or perfect but it'll work, and the whole thing cost me less than a buck in real money.
That's damned near free.
