Two rocks of anything, including flint, are very difficult to get long life sparks from. When you hit a steel with flint, the sparks are actually the burning molecules of carbon in the Steel. Not the iron in the steel. Pyrite is an ore with iron in it, and is what is used for those tiny cigarette lighter "flints". Iron Pyrite was also used in the original Wheellock guns made in Europe in the 1400s. The wheellock is actually the same design for making sparks that now appear in cigarette lighters. The only difference is that a huge spring was wound up and held by the Trigger, which when pulled, released the spring and put a spin to a serrated wheel that was in contact with the pyrite to produce the sparks. Today's cigarette lights require a manual turning of the wheel to produce the sparks. If you can find ask or carbon from a burnt stick at an old campsight, or from a fire started by lightning, to rub on your tinder, The blackness of that carbon and the carbon itself will help hold an ember from sparking your flints. Charred clothe is another form of tinder that will work for you. But its very hard to produce sparks that can be directed towards your tinder by bashing two rocks together. Even wrapping the charred cloth around one rock and then bashing it against the other may actually prevent enough of a blow to create the needed spark. Its very hard to do.
