Well, just remember, all we're trying to do is shave enough pieces ofsteel off the frizzento hit the primeand give ignition.

"ideally"...the front edge of a knapped flint would look sort of like the edge of a serated bread knife...viewed from one side (the tope of the flint) it would apopear to be fairly straight across, and viewed from underneath it would look like the "scalloped" side of a serated bread knife....."ideally".

However, as they wear from use they'll get an occasional chip or corner broken out but as long as they're still shaving steel off the frizzen and igniting the prime, that's all you rreally care about.

Knapping is mainly intended to get rid of a dull flat spot that develops as a flint begin wearing down from hitting the frizzen...sooner or later, a dull flat spot will occur, then it"holds off" the rest of the sharp flint edge from touching the frizzen...knapping is really simply to get rid of the flat spot so the flint's sharp edgecan impact the frizzen andwork again.
