Close to 2&1/2" by a wide, wide 2", but only some 5/16" max thickness on this Gibson County, Indiana Wabash River find--a number of Hopewell sites are stretched along the Wabash, decades past they produced big, wide blades like this Snyders. Modern farming techniques, I doubt many big points are ever found along those bottomlands, though. This big point very likely started (as a knife) with a considerably longer blade, but if you study the base I doubt it EVER had an intact basal corner that seems to be where your eyes are drawn--the shape of the large hornstone flake the Woodland culture hunter began working, I think there was slightly less flint to form a basal corner once the blade had been made as large as the knapper could "squeeze out"--study that rounded-in flake, it isn't damage, it was the edge of the flint piece the knapper began working--he made it fit, it tied-on the handle as-needed. Every detail is 100% guaranteed authentic, just a large, well made Snyders. Shipping is $8.00, checks or M.O.s are how I take payments. Sorry, I do not use paypal-type services--Roy A.
