A point type I think one person will view as a Dovetail, the next might call a Lost Lake--and you may even get "Early Archaic Bevel" advocates. Personally, that "Bevel" is where I am. Both left blade edges show a remarkable pressure chipped bevel sharpening technique, and the basal edge--where intact--shows excellent basal grinding. The piece is from a collection built up in the Ohio River floodplain in Spencer County, Indiana, according to the friend who bought the collection ten or so years back--that was what the finder told him. The piece is Indiana Harrison County Hornstone3& by 1&3/8". A number that'll tell you how much blade was 'used up' by repeated sharpening is the thickness: in the blade-center the thickness is barely under 7/16"--a blade that started much wider, much longer. See the close ups of the bevel, you'll understand, well made piece that shows years of sharpen-and-use--and patina. There is ancient damage to the basal corner, there may even be a farming-made chip on that small spot--that's part of its history, too. It's REAL. Shipping is $8.00 with checks or M.O>s welcomed.
