seriously, I purchased this from the man who dug it up while using heavy equipment not far from downtown Knox, this was in the 1960's. Getting older and selling his artifact stuff he had accumulated in the 1960's. He had stuff from pennsylvania and ohio. He told me this was kicked up along side a small creek that was being over run with heavy machinery knox county I believe was the scoop on this. 

I figure this is worth many ancient spear points
