? before Homo ( Pliocene) A stone tool is, in the most general sense, any tool made partially, or entirely out of stone. Although stone-tool-dependent cultures exist even today, most stone tools are associated with prehistoric societies that no longer exist. The study of stone tools is often called lithic analysis by archaeologists. Stone tools may be made of chipped stone or ground stone. A person who makes chipped stone implements is called a flintknapper. In addition to tools, many minerals were used to make arrow heads and spear points. Chipped stone tools are made from cryptocrystalline materials such as chert or flint, radiolarite, chalcedony, basalt, quartzite and obsidian via a process known as lithic reduction. One simple form of reduction is to strike stone flakes from a nucleus (core) of material using a hammerstone or similar hard hammer fabricator. If the goal of the reduction strategy is to produce flakes, the remnant lithic core may be discarded once it has become too small to use. In some strategies, however, a flintknapper reduces the core to a rough unifacial or bifacial preform, which is further reduced using soft hammer flaking techniques or by pressure flaking the edges. More complex forms of reduction include the production of highly standardized blades, which can then be fashioned into a variety of tools such as scrapers, knives, sickles and microliths. In general terms, chipped stone tools are nearly ubiquitous in all pre-metal-using societies because they are easily manufactured, the tool stone is usually plentiful, and they are easy to transport and sharpen.
