There are two different, but at the same time, very similar tools - pliers and pliers. Many people mistakenly believe that these words are actually synonyms. There is nothing surprising in this, because the instruments are actually very similar to each other. In reality, everything is not as simple as it seems.
Pliers and pliers are similar, but they are two tools with different functionality. It should be noted right away that most of these tools today that you have to see on the shelves of hardware stores are just pliers. This is because this tool is much more versatile and utilitarian, it can cope with a large number of tasks thanks to its advanced functionality. Pliers are hardly used today, but their name is indeed used synonymously due to the similarity of the two tools and some "historical inertia". Most likely in the near future, pliers will generally be blown out of use and can only be seen in museums.
Pliers were the first in the history of mankind. Used this hinge-pliers tool to perform locksmith and blacksmith work at least from the era of modern times. They are designed to grip parts and manipulate them with a pair of flat lips. This is where the functionality of the pliers ends.
Pliers appeared somewhat later than pliers and are a much more versatile device. In addition to a pair of flat lips for gripping parts, this pliers tool has in its design means that allow it to grip cylindrical parts (pipes), as well as to cut wire. Recesses for cylindrical parts on pliers usually have special notches and recesses.
At the same time, both pliers and pliers are essentially small hand-held vices in the first place. There are also wire cutting pliers available. It is customary to separate such a tool into a separate category: "universal pliers".
