The Light My Fire firesteel provides the necessary spark to light your tinder, camp stove or whatever else you need — and is perfect for your survivalist toolkit.
Sure your run-of-the-mill BIC is handy and skips a lot of the hassle, but a firesteel can come in particularly handy for your outdoors excursions, as awesome gear site Cool Tools points out:
Some of the most distinctive advantages are that it works when wet, it has no moving parts, no fuel to run out of, and lasts nearly 3,000 strikes.
I've used them for everything from car camping in the VW camper van to mountaineering stoves on Rainier climbs and they always are flawless. The smaller one always has a place in my first aid / survival kit; the larger one comes on car camping trips.
The firesteel in the image above will set you back $US15 at Amazon, but you can find more inexpensive mini versions for as little as $US4.
Update: Reader Richard Hackett writes in suggesting a one-piece alternative:
You should check out the BlastMatch. It is an excellent firelighter that works in basically the same way, but is a single unit rather than the thong attachment job
