This is the geologist in me coming out. Gotta get things lined out and correct.
That said - knapping one's own points is a right cool hobby.
Anyone tried actually hunting with a modern knapped point?
I went down on the river again yesterday for another batch of flint. I saw a number of bald eagles! And the biggest barge that I have ever seen on the river - it was actually 15 barges (five rows of three) hooked together and being pushed by a tugboat. It was too hot yesterday, I should have waited until today.
Looks like another good haul, HK. That should keep you busy this winter if you get snowed in for awhile.I went down on the river again yesterday for another batch of flint.

Man... Knapping is sooooo much more difficult than it looks.
