A much higher grade Mid Archaic Culture Three-Quarter Groove granite Axe from the Jefferson County, Illinois, area--length is 4&5/8" by 2&5/8", max thickness is 1&15/16"--same on both front and back groove ridges. The piece was a field find, but each face has only a small plow scratch--unusual for so few, so I'd suspect the Axe was found long decades back, before chisel plows. While the bit is intact it is not sharp, The bit end was never polished, no more than the body of the axe. On the bottom edge of the back ridge a small break out shows, possibly for inserting a tightening wedge--that's not a place you'd expect use-made damage, so it could be functional. In the center of the heel is a phenocryst--a quartz-like inclusion--it shows yellow, if you see it in the pictures. Every detail of the Axe is lifetime guaranteed authentic.
