there is a complete science based on stone tool, and more specifically stone point design. For instance, the oldest point design in North America to date is known as "clovis" points:



There are points found on other continents which very closely resemble clovis and Dalton designs found in North America..I find this fascinating..even when we look at stone "knapping" technique (the flaking of stone to produce a sharp edge and sculpt stone tools), it is unbelievable to me that two or more pre-historic cultures divided by vast oceans could be using the exact same technique for tool production..
