These very rare and VERY early paleo tools are some of the most interesting of all in the paleo tool kit in my opinion. This square knife has several cutting edges and appears to have been made for multi pupose cutting. Made of the highest grade of coastal plains chert with excellent color and very high river polish and this baby GLOWS when backlit. The pictures truly do NOT do this artifact any justice, you have to put it in your hand to experience what I am talking about. Please call for pricing.
