A continuación veremos algunos de los distintos tipos de herramientas, su función y el funcionamiento de cada una de ellas. Se pueden categorizar las herramientas en función del tipo de trabajo que realizan: de montaje, sujeción, golpe, corte, unión y medición y trazo.

Strike or percussion tools

Strike or percussion tools are used to hit objects such as: hammer, mallet, etc. These include the following tools:

cutting tools

There are different types:

Measuring tools

Finally we find the measuring and tracing instruments, which are used for the purpose of tracing, diagnosing and checking proportions of a design, manufacturing, control, research, and maintenance process.

Measurement activities consist of comparing a magnitude with another of known value, and what is measured are lengths (length, width and height), angles and depth of a technical object; or electrical, electronic and engine performance measurements are made.

The measurements obtained from this activity are not completely exact, due to the precision of the instruments, that is, their type. Measuring with a ruler that gives us millimeter precision is not the same as measuring with a vernier that measures us in tenths of a millimeter. Another factor that can affect the precision of the measurements is the experience of the operator using the instruments.

The measurement systems used are decimal metric and English. To transfer measurements we use compasses: points (interior and exterior) and, in angles, with a false square. The stroke consists of transferring the data from the graphic representation of a project to a piece, to later preform and shape it. To carry out this you need a manual, rules, squares, a compass, a gramil and a scorer.[9]​.

operation.

A level "Level (instrument)") is a measuring instrument used to determine the horizontality or verticality of an element.

There are definitions of the human being that explicitly mention the making of tools as an exclusively human activity that is not available to other beings. Hence, when primatologist Jane Goodall told Louis Leakey that she had observed a chimpanzee "fishing" for termites with a twig, her mentor replied: "Now, we must redefine man, redefine tools, or accept chimpanzees as humans!" [10]​ Perhaps the majority were those who were inclined to change the concept of a tool, but since then this behavior has been documented not only in many other primates, but also in birds and even cephalopods.

Recently, a Visayan warty pig was observed using a stick to dig a hole in the ground in a French zoo.[11]​.

Like other animals, early humans used their bodies to get what they needed: they dug wells, cut meat with their teeth, etc.

The first tools used by primitive humans were elements that they used in their natural state and that they found in their environment, such as stones, animal bones and sticks,[6]​ which they knew how to use as weapons or defensive means.

Approximately 3,000,000 years ago, humans began to carve stones,[7] hitting a hard stone with a softer one, such as flint, for example, making arrowheads to use them as weapons, or creating sharp edges that would allow them to cut meat or wood. This is how the knife, the axe, the saw and the lathe appeared. With animal bones or fish bones they created the first needles, using plant fibers or thin strips of leather as thread, which they used to sew their clothing.

Gradually they mixed their inventions to create more complex ones, for example a sharp, saw-shaped stone was added to the handle of the hammer, and the sickle was created, which was used to harvest the harvest.

Thanks to these advances and combinations, today there is a wide variety of tools: pencils to write, erasers, treadmills, cars to move more quickly, computers to write or connect with the world, etc., each and every one of them allows us to carry out activities more easily or simply allow us to do things unimaginable a few years ago.[4]​.
