Nope... nothing as vaporous as that! The fuel that is burning is quite solid and rather hard! The sharp edge of the flint serves to shear off that which is heated up by friction (caused by the cut) to burn.
My original question was about using noviculite as the sharp edge (rather than flint) and a piece of iron pyrite. Here in the spoiler is the answer to the question.It's a YouTube vid using a steel striker rather than iron pyrite, but iron pyrite works almost as well and was the originally used item before the Iron Age came around. The exact answer is at 3:27
I've got to leave so Sneaky... how about you or Pooh giving another question.
