How well a lock deals with flints largely depends on the angle the flint strikes at, A long flint and bevel down that hits square on is going to shatter the edge back fairly quickly. You can knap the sawn flints using a short 3/16" brass drift and a mallet or a short starter with a head shaped like a mallet. Angle the drift forward about 45 degrees so that you are driving back parallel to the bevel (down) and only engage the very edge of the flint with the drift. Except that they are easier to grip with the jaws, I still prefer english flints :>) Something that is in my bag of round twoits, is to make a couple of extra top jaws for one of my locks. What I intend to do is to put a short pedestal on the back of the jaw so that it is held farther away or up from the bottom jaw. Point being is that when you get those damn triangular flints with a ridge in the middle, the reason they do not hold well is that the top jaw is angled up. Using a top jaw with a pedestal or thickened back portion forces it to angle down on thicker flints. Hope that is not too confusing

would you have a pic of one that looks as it should after you've knapped it?
I have the totw brown bess knapping tool, would that actually do the job?
