Undoubtedly, they are simply recognizable with the correct use of each instrument and tools, that the right tool is used for the current task.
The tool's effectiveness was greatly improved by attaching the handle to a sharp piece of stone, giving the tool better control, more energy, or both. Once understood, fire helped shape wooden implements before rock tools suitable for that purpose were available. The current range of tools has as common ancestors the sharp stones that were the key to early human survival. Power tools, generally portable motor-driven implements, such as an electric drill or electric saw, perform many of the old manual operations and, as such, can be considered hand tools.
For archaeologists, the discovery of primitive cutting tools made intentionally indicates and confirms the early presence of humans at a site. The common denominator of these tools is the extraction of material from a workpiece, usually by some type of cutting. At first, humans were occasional users of tools, using convenient sticks or stones to achieve a purpose and then discarded them. The Pleistocene and the Stone Age maintain an approximate correspondence, since, until the first use of metal, some 5000 years ago, rock was the main material for tools and implements.
With the parallel development of agriculture and the domestication of animals, some 10,000 years ago, the numerous demands of an established way of life led to a greater degree of specialization of tools; the identities of the axe, the hoe, the chisel and the saw were clearly established more than 4000 years ago. Hand tool, any of the utensils used by artisans in manual operations, such as chopping, chiseling, sawing, filing or forging. Despite these qualifications, the sequence of stone, bronze and iron is valuable as a concept in the early history of tools. A tool is an instrument or device that is used directly on a piece of material to give it the desired shape.
While humans may have shared this trait with other animals, their differentiation from other animals may have started with the deliberate creation of tools for a plan and purpose.
