The Neolithic period marks a significant stage in human cultural evolution, generally dated between about 10,000 BCE and 3000 BCE in different parts of the world, while in the Indian subcontinent it appeared at different times in different regions. The most distinctive feature of the Neolithic culture was the development of ground and polished stone tools, which reflected advances in technology, agriculture, animal domestication, and settled village life. These tools were more refined, durable, and specialized than those of the preceding Paleolithic and Mesolithic cultures. Neolithic stone tools were manufactured mainly from hard igneous and metamorphic rocks such as basalt, dolerite, granite, and quartzite. The process of tool making involved selecting suitable raw materials, flaking them into rough shapes, pecking the surface to refine the form, grinding it on abrasive stones, and finally polishing it to produce smooth and sharp cutting edges. The polished surface increased the strength and efficiency of the tools and reduced friction during use. The most characteristic Neolithic tool was the polished stone axe or celt. Celts were usually oval or
