What is a chopper?
In archaeology, a chopper is a type of stone tool that was made and used by early humans during the Lower Paleolithic period, which began around 2.6 million years ago and ended around 195,000 years ago.
Choppers are characterized by their large size, irregular shape, and heavy flaking on one side. They were made from hard stones such as quartzite or basalt.
Choppers were used for a variety of purposes, including chopping wood, butchering animals, and scraping hides.
