A trove of nearly 600 obsidian handaxes, dating back at least 1.2 million years, has been unearthed in Ethiopia, indicating the presence of a prehistoric “knapping workshop”.

Knapping is the technique used to create handaxes, which are often referred to as humanity’s “first great invention.”

Made by chipping shards off a piece of stone to make a sharp edge, handaxes were not attached to handles, but held in the hand. They have a distinctive teardrop or pear shape. They were made out of flint or, later, obsidian – a type of volcanic glass.

The first handaxes in the palaeontological record date back to at least 1.5 million years ago and were found in Tanzania’s Olduvai Gorge.
