Neolithic on Wikipedia. An array of Neolithic artifacts, including bracelets, axe heads, chisels, and polishing tools.
Neolithic stone implements are by definition polished and, except for specialty items, not chipped. The Neolithic Era, or Period, from νέος (néos, "new") and λίθος (líthos, "stone"), or New Stone age, was a period in the development of human technology, beginning about 10,200 BC, according to the ASPRO chronology, in some parts of the Middle East, and later in other parts of the world[1] and ending between 4,500 and 2,000 BC. Traditionally considered the last part of the Stone Age, the Neolithic followed the terminal Holocene Epipaleolithic period and commenced with the beginning of farming, which produced the "Neolithic Revolution".
It ended when metal tools became widespread (in the Copper Age or Bronze Age; or, in some geographical regions, in the Iron Age).
