The break is some ten thousand years old, maybe even an extra thousand years, depending on the source you read--material is my "local chert"--Spencer County, Indiana, area Holland Chert--Chalcedony. What the finders' estate included was only the base--maybe he found the tip, maybe it's still out there along the Wabash River somewhere, buried. Length of this basal section is 2&3/4", so presumably the full length was once 5 &1/2". Width is 2&5/8", thickness ONLY at 7/16". If you study the length of the long flakes "Outre Pas" flaking where a flake extends past the medial ridge, that's where you know a Clovis hunter made the big blade--it took Mammoth ivory to make those type flakes properly--a 'harmonic resonance' is what a skilled knapper, a student of Paleo techniques, explained to me; a shock wave, it traveled farther with an ivory billet ( he used one from a "Far East" country to replicate Clovis knapping). Now, would this huge knife ever have been reduced to a true Clovis point? Likely not, it (as a knife) was made for cutting up gigantic game, REALLY big game. One note--the edges of the break-off are worn, particularly on one face, indicating the knife became a hide polishing tool. Waste not...want not; it was too harsh of a landscape to travel fifty miles for a new flint block to work. Best--Roy A.
