Ground Stone
Flintknapped, or flaked, stone tools have a distinctive rippled appearance, because of the way they are made by detaching flakes. Archaeologists also find stone tools which have a polished, smooth surface. These are called ground stone tools, because that's how they were made, or more precisely, how they were finished. Ground stone implements can be quite diverse, ranging from bowls, pipes, and lamps to knives, points, and axes.
Ground stone tools are not usually made out of the same type of rocks as knapped tools are. The stone most suitable for grinding is typically not the stone most suitable for flaking. Granites, quartzites and basalts, which are not nearly as nice to knap as finer grained cherts and natural glasses, can be made into serviceable tools by pecking and grinding. Another example of stone suitable for grinding is soapstone (steatite or talc-schist), which can be shaped into a variety of forms, including lamps, bowls, or pipes. Inuit and their prehistoric ancestors are famous for their work in soapstone. Slate is also a common grindable stone. It can be ground into flat, sharp cutting and piercing tools, like the bayonet pictured on this page.
