Hand axe

1000 Inventions and Discoveries – Hand axe (c1,800,000BC)

Over a period of more than one million years, the first crude stone tools evolved into beautifully shaped blades.

Their makers flaked away the surfaces of a large flint pebble until its sides were sharp, for cutting or scraping, and one end was pointed, for piercing.

The remaining blunt end fitted snugly into the hand, which is why the blades are called hand axes.
