The ability to create and work with tools dates back to an incredible number of years in our family tree. Even Chimpanzees, could by themselves design spear-like tools for hunting and create specific tool for foraging ants. The dawn of stone tools dates back some 2.6 million years to Gona in Ethiopia. Generally known as the Oldowan, the tools include not only fist-sized hunks of rock for pounding, but the first known stone tools — sharp flakes made by knapping, or striking a hard stone against quartz, obsidian, flint or some other rock whose flakes holds an edge. At that time also the most ancient butchered animal bones were also employed as tools.

Such was the scope of the technology for about a million years. It was probably very ad hoc — when you needed a stone tool and you didn't have one, you just made one, and then dropped it.

Ahistory of toolss tool use advanced, somewhere along the line, there were significant changes in social evolution. Scientists assert, for example, that when provisioning or the sharing of food started in Homo erectus, there was an increase in female size, which many argue that it signifies that infants are born less mature, hence needing more maternal care. So the suggestion is that more provisioning will help females find something to eat.

The plough is most likely the first implement which human beings use, a source of power apart from their own muscles. When planting seeds, it is necessary to break up the ground. In the beginning of agriculture this is accomplished by hacking and scraping with a fittingly pointed tool - the antler of a deer, or a hooked branch of a tree. Nevertheless a useful furrow can without difficulty be achieved by dragging a point along the surface of the ground. The first ploughs contains a sharp point of timber often hardened in a flame or tipped with flint and projected downwards towards the end of a lengthy handle.

In the light soil of Egypt and Mesopotamia, where ploughing is initially carried out, an ordinary pointed tool of this kind is enough to breakup the earth and form a low trench. This kind of a plough can be pulled by a number of men. But the usage of draught animals like oxen, from at least 3000 BC, tremendously accelerates the process.

In the northern region of Europe, with heavier soil, this kind of plough is a waste of time. A much more elaborate machine is produced, possibly by the Celts in the 1st century BC, wherein a sharb blade cuts into the earth and an angled board spins it over to form a furrow.

In the computer-driven Information Age, we don't actually think of fire or tools as technologies. However by definition technology refers to the "practical application of knowledge in a particular area. Discovering how to use tools and tame fire proved an all-important technological advancement in human development.

These days machine tool are used to manufacture metal components and parts of machines by way of machining, a procedure through which metal is selectively removed to make a desired shape, this Varies from simple to complex pieces. They can make parts of various shapes and sizes.

Machine tools have progressively developed over the past millennia. At present, machine tools are used on computerized numerical control machines that could repeat sequences with precision, and produce complex items of different sizes and shapes.
