Hand tools are a tool for transforming and conquering nature that was created and developed at the same time as human beings. The original hand tools were very simple, such as sticks, angular stones, etc. After humans were able to finely process stones or animal bones into stone axes, stone knives and bone needles, they began to use more complex hand tools. Around 4000 BC, metallurgical technology began to appear, which led to the separation of agriculture and handicraft industry, and also improved the manufacture of hand tools. Modern hand tools still retain the characteristics of the original hand tools, such as hand pliers created in AD 300 and sets of wrenches for tightening and loosening screws, which are still in use today.
With the development of modern machinery and metallurgical technology, hand tools are constantly updated and developed in terms of shape design, material use, etc., fully considering design factors such as mechanics and human body functions; with the development of social economy and the fine division of industrial production, The manufacture of hand tools is more specialized and the functions are more diversified, and special supporting hand tools such as vehicle-mounted tools and electronic instrument assembly tools have appeared.
Hand tools are a relative concept, mainly referring to the difference from machine or automation driven tools. It gets its name from the fact that it is driven mostly manually. Some tools can be used by hand or installed on machines or automatic mechanisms, so there is no strict distinction between the tools themselves.
Hand tools can be divided into cutting tools and decoration aids according to their functions, and can be divided into screw and nut assembly hand tools (such as wrenches, screwdrivers), construction hand tools, and gardening hand tools (scissors, sickles, shovel knives) according to their functions. , tree branch shears, etc.) pipeline hand tools, measuring hand tools, woodworking hand tools, welding hand tools, etc. Common hammers, files, knives, pliers, saws, screwdrivers, wrenches and diamond tools, etc.
