Ft. Payne Flint (or Muldrough Flint) Early Archaic Cobbs Knife. The tip area is NOT restored, tap it against other flint and it rings with the sound only hard flint produces-- a 'ding'.. Note a surface flake exfoliated below the tip, it shows a dark gray color where there is no 7500BP patina. Whatever minerals that band of flint was exposed to, it patinated dark gray flint to a brown, but didn't change the white inclusion of the tip itself; much harder flint at the very tip. Total length is 4&1/4" by 1&15/16", the Cobbs Knife slightly over 3/8" max thickness. The blade edges are bevel sharpened and pressure flaked, one edge showing a shaft scraper indented. The piece came through an Indiana estate, not marked as to county--or if the piece could have been purchased from a Kentucky finder, the flint being found in Indiana and Kentucky counties west of Louisville, Ky--you have the area, though. Every detail is guaranteed authentic. Shipping is $8.00. I welcome checks or M.O.s, however I do not use paypal--Roy A.
