Paleo-Indians living in western New York State engineered stone tools with surfaces that had more than one tier along its length. In this example, we present two such artifacts, the first, a rectangular piece with a two-tiered surface on one side. The second is a large stone blade with a three-tiered surface.
Artifact number one may be a multi-purpose tool that functions as a hammer stone as well as a wood planer. The tip of the artifact is angled, allowing the tool to split wood or other material.
Artifact number two is a curved stone blade we call “The Stone Sword”. This tool has a straight edge blade on one side and a curved blade on the other giving the artifact the appearance of a sword. This artifact is basally thinned, perpendicularly to the surface and notched for precise hafting. Could it be that swords were originally a North American invention? This stone sword is some 7000 plus years older than the bronze age swords which were invented in the middle east around 1600BCE.
