Just under 2&21/2" by 1&1/4", yet only slightly over 1/4" at the single thickest spot of the banded Indiana Hornstone. The piece is related to the Benton Culture, from a site in Warrick County, Indiana. As you'd expect with a Mid Archaic, there is hardly any basal edge grinding--those 6500BP peoples could do some fantastic knapping, make some extremely skillful hafted knives, but basal grinding simply wasn't their way of finish-out. Note on the edge of this knife/ point there is a very long edge fracture on one blade side--was it accidental, or was it a deliberate technique? For a break, it doesn't compute, it's too long (runs from barb tip to within 3/4" of the tip itself_; how'd they do it? The fracturing had to add something to the piece--assuming it was intentional. Neat feature. Every detail is guaranteed authentic. Other history: the piece has been in my collection since 2010--it's real, it's interesting, and the flint is good--three features I think make it collectible. Shipping is $6.00, checks, cash, or M.O>s welcomed. Sorry, my store doesn't take paypal--Roy A.
