Neolithic tools
The Neolithic Period, or New Stone Age, the age of the ground tool, is defined by the advent around 7000 BCE of ground and polished celts (ax and adz heads) as well as similarly treated chisels and gouges, often made of such stones as jadeite, diorite, or schist, all harder than flint. A ground tool is one that was chipped to rough shape in the old manner and then rubbed on or with a coarse abrasive rock to remove the chip scars either from the entire surface or around the working edge. Polishing was a last step, a final grinding with fine abrasive. That such a tool is pleasing to the eye is incidental; the real worth of the smoothing lay in the even cutting edge, superior strength, and better handling. The new ax would sink deeper for a given blow while delivering a clean and broad cut; its smooth bit, more shock resistant than the former flaked edge, had less tendency to wedge in a cut.
