I know you guys may be too busy to handle all requests, but I have been trying to find out more about the two items I unearthed when I was a teenager. I would desperately like to know more about these items, and have not been able to come to any solid conclusions about their exact use, or type, much less an approximate age.

These two items are dear to me since I found them at my grandparents place, who have since passed on. The location was the foothills of NC near Winston-Salem and the edges are relatively sharp. The smaller object seems to be a unifacial object since one side is much more flat than the other. I would greatly appreciate any
information you might be able to pass on based on the photos. Thanks a lot…
