As drills go, 2&9/16" is pretty good length--width across the base is 3/4" and the thickest spot is 5/16". The piece comes from either Spencer or Perry County, Indiana, along the Ohio River--that's where the collector hunter. The flint is Sonora Flint out of the E-town, KY area--it shows too much hematite color to be Indiana Hornstone--that red-maroon color is usually a give-away for Sonora Flint. One photo should show the drill on-edge so you can see there is slight tip-to-base curvature. Based on the almost total lack of basal edge grinding I'd type the piece as a converted Late Archaic Period point style although there are some Mid Archaic points with that base style as well. One note--you can see the basal thinning flakes the knapper snapped so the drill could be hafted; it looks like he used a fluting gig to get that double basal thinning, holding it in-hand would have been pretty hard to do when you're trying for a very precise basal thinning.. Patina is excellent, every detail is guaranteed real. Shipping is $8.00, checks or M.O.s are welcomed. Sorry, I do not use paypal-type services--Roy A.
