Shipping cost is included, no additional auction fees, buyers' premiums, ant=y of the 'extra charges' auction services tack-on. So--what you get is a stunner of a Gibson Point (Late Hopewell) or Motley from a Montgomery County, Illinois, collection--the proverbial "paper thin"--my caliper touches 1/4" at the center of the stem, but the blade is almost all 3/16" or thinner. That's some impressive knapping by the appx. fifteen hundred-year- past artisan. Length of the fossil chert is 3&1/8", 1&5/16" wide across the barbs. To mention the basal corner hardly needs saying, but it looks like that basal tang has been clipped-off for many years. I see very slight wear on the barbs--not really damage so much as simple use. So, to wrap up, there was slight ancient use but not much of it, the knife was far too fragile to be an "every day knife"--you wouldn't have made a piece this thin, as well knapped if all you wanted was a butcher knife--this was ancient art, and it's 100% guaranteed authentic.
