Not sure on the clearfork scrapers but if that's what they are the purple banded one about the third on the left from the bottom is a beauty and I came home a day to early it rained two inches there last night.:(
Yep, Clear Forks, I know them well. Seems like So.Tx. was the epi-center for woodworking tools. A real Lowe's and Home Depot for the ancients. That purple is rare but I have found a couple of broken unstemmed points that were made of that color of flint.
I'm back SH. Did make a large donation to the Coushatta Indians and got most of it back. A real Indian giver I am.
