The 'Swiss knife' of the Stone Age
The hand axe, the longest-used tool in human history, was already in circulation around two million years ago in Africa. The hand axes found in Eurasia were much younger however, dated back to 600,000 years ago. The all-round tool was likely to have different functions such as chopping, cutting, scraping, hitting and even throwing. This piece of flint stone is at most 35,000 years old.
