I've played with a bunch of different fire-producing products.

Blastmatch - this does create quite a lot of sparks, but it is heavy and unless you can place your firestarting material on a sturdy flat rock, it has a good chance of knocking the material around while striking.

Sparklite - Incredibly small and light - almost makes me wonder what's missing. One-handed. Easily creates sufficient sparks to ignite a cotton ball (with the outter surfaces impregnated with petroleum jelly). I find the handle a bit small for my big clumsy hands. I have a slight concern that the wheel could jam up, leaving me without any sparking capability, BUT have not encountered such a problem.

Boy Scout Hot Spark - Very inexpensive. Almost as small & light as the Sparklite - almost. Available at most any Boy Scout store around the U.S. This is a small version of a fire steel. Really not much to break or malfunction.

Kershaw Fire Steel - I think this is the typical fire steel imported to the U.S. by Kershaw. I'm not thrilled with the striker - may switch to hacksaw blade. Somewhat large. Not too heavy. Two-handed. Easier to spark than Hot Spark just because its larger.

Piezo Lighters - Windmill, Storm - creates a strong, but almost invisible flame (need a glow-wire that glows to let you know its working). The Windmill lid flips farther away from the flame than does the Storm (the Storm's is simply too close for easy use - hits the firestarter). I hear that if these get wet they will malfuntion until they dry out, but haven't experienced that yet.

Bic Lighter - No lid to get in the way. Gives a nice-sized flame. Over time the mechanism can corrode and sieze-up. Pretty reliable.

When car camping I like the long butane lighters. Earlier Bic models had a nasty habit of not lighting. It appears the newer model has fixed that. I wish someone would make a shorter version this still gets the flame "out there" but could be carried more conveniently.
