Stone Tools Inventions – Great Inventions in our World
Stone Tools is the best materials in Our world- by TRc
A stone tool is the most general sense. Although stone tool-dependent societies and cultures still exist today. One simple form of reduction is to strike stone flakes from a nucleus (core) of material using a hammer-stone or similar hard hammer fabricator.
The very first human invention consisted of sharp flints, found and used in their natural state by primitive peoples, who then went on to purposely sharpen stones. The practice reaches back to the very dawn of humankind, stone tools found in 1969 in Kenya are estimated to be 2,600,000 years old.
The principal types of tools, which appeared in the Paleolithic period, and varied in size and appearance, are known as core, flake, and blade tools. The core tools are the largest and most primitive, and were made by working on a fist-sized piece of rock or stone (core) with a similar rock (hammer stone) and knocking large flakes off one side to produce a sharp crest. This was a general-purpose implement used for hacking, pounding. Or cutting. Eventually, thinner and sharper core tools were developed, which were more useful. Much later, especially during the last 10,000 years of the Stone Age, other techniques of producing stone artifacts-including pecking, grinding, sawing and boring-came into play.
The evolution of tool making enabled early humankind to complete many tasks previously impossible or accomplished only very crudely. Animals could be skinned, De-fleshed, and the meat divided up with stone cutters, cleavers, and choppers. Clothing was made from animal hides cleaned with rough stone scrapers and later punctured with awls. Hunting became more efficient with spearheads fashioned from stone flakes. And with the aid of stone adzes (axes), early humankind could create shelter and begin to shape the physical world to its liking.
