This GENUINE African Acheulean prehistoric stone tool is a large UNIFACIAL KNIFE. It was made and used by Homo ergaster (African Homo erectus) over a half a million years ago! These unifacial blades were the EARLIEST form of a knife made by humans, in the Stone Age. It was surface-collected from an exposed Acheulian site in the Northern Sahara Desert of Northwest Africa. These Acheulean Lower Paleolithic tools represent the first intelligent design type known to science, made by primitive humans. Prior to these Saharan Acheulian tools, only crude pebble tools existed in the human fossil record.
With hand axes being the predominant Acheulean tool found, flake tools are fare more scarce. Acheulian knives from the Sahara, are VERY RARE and often overlooked in field collecting, making them rarely seen in collections. This type of flake tool is fashioned by striking off a large long flake from an even larger tool core. Edge photo shows intact prehistoric secondary flaking all down the cutting edges made by its original primitive human maker. All cutting edges exhibit excellent workmanship and extensive use. A bi-colored patina can be seen from this artifact laying undisturbed on the exposed desert floor, for hundreds of thousands of years.
During this time in prehistory when this Lower Paleolithic tool was made, the Sahara Desert was a savanna rich in wildlife. Prior to the prehistoric global warming that turned the vast region to desert, early humans lived alongside prehistoric giraffe, bison and elephant, which were vital to their survival. Hunting and butchering these animals would have required specialized tools such as this Acheulean specimen.
