Thank you everyone for the information. We think it is beveled but not positive. You will have to excuse our lack of knowledge here, we are still new to finding artifacts. Hopefully maybe this picture can help.
Welcome to TNET. I'm also in E. Cent. IL near Shelbyville Reservoir and we would definitely call that a Stanfield. Early archaic, dovetail related. They used a nice clean piece of Burlington flint from the IL River Valley. Gary
