"Crude Tool" Again

Here's that possible hand tool again, from over by some power lines, on a hillside that I think contains alot of turtle "sculptures," along side of some other possible tools, all of a nice "turtle foot"shape, to be stored at the site...
























Turn them over and the top four have very smooth sides. The new power line one doesn't...























I can hold it a couple ways and see some more working edges perhaps...


















...maybe even a big drill looking thing...


















...but maybe it was broken and never used much - except maybe as a turtle foot on a hillside full of effigies...























The "worked/knapped" edge...


















The broken edge...
