The Invention of Stone Tools, How, When & Who Invent? – The very first human invention consisted of sharp flints, found and used in their natural stare by primitive peoples, who then went on to purposely sharpen stones.
Invention of Stone Tools
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 were made by working on a fist-sized piece of rock or stone (core) with a similar rock (hammerstone) and knocking large flakes off one side to produce a sheep crest.
This was a general-purse 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-come into play.
The evolution of tool many tasks previously impossible or accomplished only very crudely. Animals could be skinned, defleshed, 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 adzes (axes), early humankind could create shelter and begin to shape the physical world to its liking.
