Prehistoric Flint Skinning Tool. Condition is Used. Shipped with USPS First Class. I found this yesterday September 13th 2020 in a cornfield in Northwest Pennsylvania. I tried to show the napping on the edges as best I could. I turned the light on the phone to try and show more of it. It is a large chip of Flint with distinctly two large edges are knapped. This is guaranteed authentic. this can be returned for a full refund less shipping if not satisfied. Thank you for viewing! God bless the usa!
