There is an ad "to learn flint knapping" in the back of the latest Backwoodman mag.
Actually, some folks use a 5/16 inch bolt and use the threads as an edge to break off a few chips to create a new edge. Some use a piece of antler to flake the edge. I have never been successful at it.
I'll pick up a dozen flint every few years and I seem to misplace far more than I wear out. My trade gun seems to be set just perfectly. I have used the same flint for many years with not apparent wear.
