BTW, on MuzzleloadingHide, a bunch of us got together a few years ago and organized a group buy. We ordered thousands of flints and the English flintknapper was shocked with our order. I ordered several hundred myself just in case the English decided to come back for round 3. By buying in bulk, we really got a good price. It was less than .90 for a 1" flint.
Vigilantibus et non dormientibus jura subveniunt. Molon Labe!
