We seem to have ignored the original question. Scrap flint for fire starting can be found from many sources. In this game one must develop the fine art of 'scrounging' to get what you need much of the time.
My fire starting flint is a hunk of red agate. It is now about the size of a silver dollar but was much larger when D.C. Waldorp gave me a hunk of scrap. That was about 45 years ago.
