Engraving tool (c35,000BC) – 1000 Inventions and Discoveries

As long as 40,000 years ago, people were making delicate objects and works of art using stone engraving tools called burins. Made by forming a sharp edge on a flake of flint, a burin could be used to scratch lines and cut grooves in bone or wood.

This allowed people to create more precise tools, such as needles, and to engrave decoration on larger objects.
