build up your pile of shavings, get something highly flamable to start burning, strike, strike, strike, flame. get warm. Good survival tool but pretty heavy for back packing.

Throws tons of sparks for the size. Definitely still want to take at least 2 other fire starting methods. I can not comment on the striker integrity, because I usually use the back of a knife, and don't even carry the striker with me. You can light a strong fire, with just a little bit of kindling, and keep it going long enough to dry out wet wood.

I see the other reviewer's complaint, and maybe my striker will suffer the same fate. But for now, it works great. Throws a BUNCH of good sparks. Starts fire. Great to have in the pack as a primary source of fire or as a backup.

Ive lit several fires with this bad boy, throws good sparks, works way better than those Magnesium/Flint combo ones.

I don't no what happened to the guys' one below, but my mine works great.

Use Lint from the dryer as tinder!!!! Ive never had to strike more than twice using Lint as tinder, and it burns surprisingly long.

The metal striker plate broke the first time I used it.
I was even being careful because I read that they break easy. I will save the little piece that is left for emergency. I mostly use the inside edge of my leatherman pliers now. Otherwise it invaluable and fun to use... you piro.
