I am partial to the Blast Match: Blast Match

And its little brother Sparkie: Sparkie

I am not generally a fan of Ultimate Survival Technologies products as I have tested many that failed straight out of the package, but these two seem to work consistently and produce very good and hot sparks. They can even start a fire with pine needles, dry grass and leaves with no other tinder. They can also be used with one hand. I have not purchased one in a while, so I have not tried any newer ones. The older ones do work well. They are not small, and the Sparkie can have a tendency for the mechanism that locks it closed to fail, but it still works to produce sparks.
