Oklahoma found natural Native American knapstone/chert/flint/jasper

I find these myself at a campsite located in the Ouachita National Forest in my native state of Oklahoma. Though found here this is only their final resting place, being brought here by indians hundreds of years ago as a trade item. They also of course made arrowheads and other primitive weapons by chipping away at the stone. Valued and used for it's unique properties such as being easily (relatively) shaped into points and having a very sharp glass-like edge when broken. all stones are hand cleaned to remove any dirt or debris. I have small flakes to larger palm sized and above stones. I am open to negotiating and will consider any offers made. smoke free/pet free home. Thanks for looking.
