Neolithic tools were mainly made of hard stones like flint. Chalk and limestone contain flint. There are various colors of flint like blue black and dark brown.
Hand-axes, knives, scrapers, diggers, arrowheads and spearheads are examples of Neolithic tools that were made of flint. A digger was commonly used in agriculture while a scraper served purposes like slicing vegetables and cleaning animal hide's insides. Both arrowheads and spearheads were used for hunting various-sized animals.
"Neos" is a Greek word that means "new." The Neolithic Era, which means "new stone period," is different than that of the Old Stone Era in terms of climate. During the Neolithic age, the Earth warmed, giving much positive impact to human and animal life.
