Here's a Kentucky side notch Big Sandy with a slightly tilted asymmetrical base. Typical Sonora colors are dark gray and purple. Ex Gary Noel. I bought this from Gary so long ago I can't remember the year...lol. It's a fine example of Sonora with a ground hafting area, fine serrations and pressure fluted on both sides of the base. Slight rhomboid beveling with a fine tip. This is a great example of the Sonora lithic material as well as an early example. It measures 2.5 inches long with no damage. As always, guaranteed authentic and ancient. Payment: Venmo, Paypal or Cash. Buyer may pick up or pay actual shipping/insurance. Thanks for looking.
