Interesting. I've tried lighting a Tinder Quik with a Spark-Lite, and it worked perfectly. For me, at least, it produces sparks at least as well as a Bic.

I read somewhere that there was a protective coating on the flint, and you have to strike it a couple of times to clear that. Mine sparked the first time, so I don't know about that.

I also read that the flint will disintegrate over time without that coating, so I bought another one to carry for emergency use. I don't know if it's true, but two is almost always better than one.

The one I tested came in the AMK/Doug Ritter survival pack. Does anyone know if those are tested before putting them in the packs?

In summation: this tenderfoot survivalist had no trouble at all with his Spark-Lite.
