The Neolithic, also known as the "New Stone Age", was a time period roughly from 9000 BC to 5000 BC named because it was the last period of the age before wood working began. The tools available were made from natural materials including bone, hide, stone, wood, grasses, animal fibers, and the use of water. These tools were used by people to cut such as with the hand axe, chopper, adze, and celt. Also to scrape, chop such as with a flake tool, pound, pierce, roll, pull and leaver.
