For processing (cutting) various cables, electrical wires, or for working with a simple wire - you may always need such a simple tool as side cutters (they are also side cutters). Structurally, they are only a pair of parallel cutting planes. They are convenient for biting cables and stripping them of insulation. The best models are characterized by high quality workmanship, sharp cutting jaws, have dielectric handles and can withstand the application of great effort to them.

Side cutters are easy to recognize by their appearance, since their pointed working edges are on the same plane as the handles (and only infrequently a small angle is allowed between them in the design). They are used to cut wires or wires of small diameter in diameter, they are able to make small cuts on metal and plastic surfaces, which is necessary during installation work or when installing wired equipment. When using this tool, its cutting force is controlled by moving the workpiece closer/further in relation to the fastening hinge. The handles of the fixture are specially made large, despite the fact that the cutting jaws are much smaller than them. So it is possible to increase (by pressing) the cutting force due to the application of the "lever" effect. For example, if you need to bite a small wire of small diameter, then it is located closer to the initial edge of the sponges. And for biting a thick cable, on the contrary, it is placed closer to the fastening hinge of the tool. The cut itself occurs due to pressure on the handles by hand (palm), from which the working edges are compressed and, in fact, the incision.
Yet, no matter how simple the device of side cutters may seem, it has a clear nomenclature of the names of all its working parts and consists of:
All working elements are connected by means of a special lock with a reinforced structure. The spring (if provided) is characterized by increased elasticity and is located between the two handles. Its function is to bring the cutting edges to their original position, which is performed immediately after the end of the cut. In serviceable side cutters, the jaws are always completely closed at the end of the action. The swivel is responsible for ensuring the smooth running of the movement of all parts, which facilitates the work with the device.
The type of tool in question is often used for cutting:
Also, they can play an auxiliary role in the cut:
They are distinguished from the classic wire cutters by the location of the working jaws. Lateral samples have cutting edges that are relative to each other in parallel planes, while in classic models they are at a perpendicular angle. Although for side models in some designs a small angle is allowed. In addition, side cutters are specially designed for processing solid and stranded wires with a large cross-sectional diameter and are generally focused on working with electrical cables. Classic wire cutters are considered a more versatile tool, but they are poorly suited for fine work with some types of electrical wires.In general, this is why you can often find side cutters without dielectric protection on the handles (it is made in the form of insulating covers made of rubber and similar non-conductive materials). Classic wire cutters usually do not have such protection, so it is not possible to work with live wires with them. Often, some security of the “classics” is provided by polymer covers on wire cutters, but they are not a full-fledged insulator in the full sense of the word.
There are several types of current models of the type of tools in question on the market today, which differ from each other in design and purpose.
This is the most common type of side cutter, which is easy to find in any building supermarket. They are intended for processing wires with a cross section of not more than 2.5 millimeters.
These models are designed to perform professional work in plumbing or assembly. Their cutting edges are made on the basis of high-strength alloy steel, and they have undergone finishing production processing in the form of a special hardening, which gives them greater strength.
They are used by professional electricians, telephone technicians, in general, by all workers whose activities are related to the processing of live cables. Samples with specialized dielectric insulation are allowed to work with live wires up to 1000 volts.
Such mini side cutters are used by computer network installers, radio amateurs, system technicians, and others. They are small in size and very comfortable to operate in tight spaces.
Summing up, it can be noted that the devices under consideration can have different sizes and versions, and more specifically, they can differ in the shape of the cutting parts. It is this factor that will influence the working orientation of the model. If the sponges are long and thin, then it is convenient to work with thin wires located, for example, on electronic circuit boards. If the working sponges are characterized by a greater breadth of their surface, then they are better suited for removing the insulating coating from cables.
Despite the fact that side cutters, at first glance, have a rather simple design, certain rules and requirements should be observed when working with them:
Upon completion of work with side cutters, it is necessary to perform several preventive measures:
It is no secret that no matter how intense the cutting tool is, someday its edges will become dull, which will affect the quality of the operations. For side cutters, it is allowed to sharpen the sponges yourself.Although they can be sharpened on a special grinding machine, at home (due to the small area of the cutting surface) this can be done using ordinary sandpaper. The device is brought to the abrasive surface of the paper from the back side, and then slow forward and backward movements are carried out along the cutting edge in order to machine their working base. It is also possible to sharpen with a whetstone, but due to the small size of the device, this will be problematic. Therefore, this option should be considered only as a last resort. It must be constantly remembered that each type of side cutter is designed to process a certain type of material. If miniature models are not used on thick steel wires, they will last much longer. Moreover, most of the existing samples are designed for processing mainly copper and aluminum cables and conductors.
Nowadays, in any building supermarket, as well as on a specialized trading platform on the Internet, you can easily find and buy the desired model of side cutters. However, before buying, you need to decide on the future scope of use, carefully study the specifics of the design of the tool you like, and familiarize yourself with the possibilities of its working stroke. If intensive use of the device is expected, then it is better to prefer ergonomic samples that will be more comfortable to use. If infrequent operations at the household level are supposed, then miniature models will suffice for them.
For home labor-intensive operations, mini side cutters are easy to use, which will successfully cope with the repair of electronics or household appliances.If processing high-voltage cables is required, then tools with dielectric handles are indispensable. In addition, they should have convenient sizes and solid cutting blades. So they will become a traveling tool for a professional electrician. For cutting knitted wire during industrial-scale operations, it is better to use reinforced models that will easily bite through a wire with a cross section of 6 millimeters. And their most powerful samples, called cable cutters, are able to cut through stranded wires with a diameter of 200 to 400 millimeters. Cable cutters, in addition to their prominent dimensions, are also easy to recognize by the diagonal shape of the working jaws. It should be clarified that some experts recommend using only a specialized tool called "sector shears" for large and stranded wires. Its working boundaries start from a diameter of 130 millimeters.
Side cutters can be double-hinged or single-hinged. The latter have the simplest design, which shows a sufficient level of reliability in any conditions. Double-hinged samples are more complex, but are characterized by the fact that they do not have to apply excessive force when handling them. This circumstance is especially important if the work is carried out intensively with the shortest breaks, and a wire with a large cross section is under processing. On double-hinged models, a spring is installed, which independently returns the handles to their original position, “unloading” the physical tension of the master’s hand.
This characteristic depends on the length of the edges.For processing network cables, operations with small electronic boards or small conductors, an indicator of 1.6 - 5 millimeters will be enough. To install the electrical wiring network when arranging an apartment, you will need a length of 5 - 15 millimeters. The largest models are those with a working stroke of up to 150 millimeters - they are designed for processing large-diameter stranded wires.
Usually, this parameter is determined by the ergonomics of semicircular handles, which should fit comfortably in the palm of the master. To ensure more confident action, it is better to choose a product equipped with covers made of 2-component material. Its relief can very simply provide additional protection against accidental slipping in the palm of your hand. Also, dielectric handles will also be useful - they will not interfere with normal operations, but they will be useful when processing live wires.
