Eighteen (18) large quarry site blades from along the Ohio River, Harrison and Floyd Counties, Indiana. Ancient peoples would gather up raw nodules and layer slab pieces of Hornstone in Harrison County, Indiana, creeks, then retreat back to the river where they could find a secluded beach to crack open nodules, pare-down the sheer weight of all the rock before they canoed for home. Whether these were cast-offs, or simply lost in the sand, for whatever reason, these flint blades were left to build up the flint 'midden' on a river beach (along with countless quartzite cobbles used and broken while shattering the tough hornstone nodules). Most of these show the limestone cortex that surrounds a flint 'spall'--the longest is very slightly under 4". The piece in the center shows what looks like an Adena stem--never finished. Many of the tools have work edges for cutting, the little 'micro flakes' that tell you the knife was actually usedThese aren't EVERY grade (or color) of Hornstone, but they definitely give you a representation of what the flint gatherers were after--neat pieces, authentic. Shipping is $10 Priority, they barely fit the shipping box, and payment has to be by check, cash, or M.O. as I do not use payment services (like paypal)--Roy A.
