Which clippers are better. Nippers for manicure and pedicure - types, brands, selection criteria and operating rules. For what kind of work are they used?

Cuticle nippers are used to remove dead skin around the nail plate. This tool is designed for professional and home use. Different models of tongs may have different characteristics that affect ease of use and safety.

How to use cuticle nippers?

The resulting irregularities around the nail plate and cuticle are removed before applying a decorative coating, for which skin nippers are used. When performing the processing yourself, you need to follow the recommendations on how to properly use the tongs:

  • Before use, the nippers should be disinfected with an antiseptic solution.
  • Hands should be washed, and the skin should be steamed in warm water. You can use special .
  • The cuticle must be pushed back and lifted with a scraper or a special stick.
  • The grip of the tool is carried out with the palm from above, then the hand turns over. The index finger is under the undercarriage (it should not be placed close to the blade to avoid injury), and the thumb is on the undercarriage. The remaining fingers are located on the handle. Only the free edge of the cuticle (non-living) should be cut. When removing the skin, hold the tool with the tips down and move at the same angle so that burrs do not form. The heel of the forceps should not grip the skin.
  • In order not to cut off unnecessary sections, it is not necessary to open the teeth wide. The bottom sheet should slightly lift the skin. When compressing the handles, the keratinized areas are carefully cut off. You can not pull and tear the skin. In the same way, burrs are removed from the side rollers.

Do not press the tool too hard, exert excessive pressure. The forceps should be handled smoothly, without sudden movements.

Criteria for choosing a professional tool

An important criterion when choosing is the smoothness of the ride. The handles should be compressed and unclenched gently, without creaking or jamming. Tight forceps are difficult to control with one hand. The softness of the move depends on the quality of the connection of the parts of the tongs. Other recommendations on how to choose cuticle nippers:

  • The convenience of the location. The handle should extend slightly beyond the center of the palm. If it rests against the center of the palm, then with prolonged use of the tool, fatigue and discomfort will occur due to squeezing of nerves and small vessels. Also, when squeezed, the handle can slip out of the palm if it is not long enough.
  • Material. Wear resistance and increased strength are possessed by products made of carbon, alloy or medical steel. Professional tongs are often made of stainless steel with a cobalt finish to reduce the harshness of chemical and heat treatments. If the type of material is not indicated on the package, you should look at the marking, which consists of two pairs of numbers. The first of them indicates the density, the value must be greater than 40.
  • The head part can be with or without a heel. Which wire cutters to choose depends on the experience with the tool. With the back of the blades extended, it is difficult for a beginner to control the cut. Inaccurate movement of the heel can injure the skin. It is easier to handle forceps that have a flat heel or a minimal protrusion angle.
  • Connection form. The nippers have a connecting mechanism with a return spring, a spiral, plates with a locking connection. There is also a hidden connection. Coil spring pliers with double spreader are the most reliable.
  • Blade shape. The blades should converge evenly, forming a sharp nose. The edges must be smooth, without defects. The shape of the teeth depends on the inclination of the edges. The lower heel position allows the forceps to be held at a lesser angle. Wide blades are recommended for experienced craftsmen, in the absence of experience, there is a high probability of cutting off excess sections.

On sale there are products with different lengths of teeth. How to choose tweezers depends on the experience of using the tool: manicure masters are advised to choose nippers with teeth more than 7 mm, but for beginners it is better to choose a blade length of 5 mm (in this case, the risk of skin injury is minimal). The longer the blade, the easier it is to sharpen.

How to sharpen tweezers?

The stronger the material of the nippers, the longer the first sharpening will not be required. When using a high-quality branded tool, the question arises of how to sharpen the blades of tongs. When blunting, the tool is sharpened in a special workshop, because. The process requires the use of equipment and skill. The wizard does the following:

  1. Checks for clearance between work surfaces.
  2. Adjusts the compression springs to return a smooth ride.
  3. Eliminates a corrosive raid in its presence.
  4. Sharpens each blade using a diamond wheel to create a sharp point.

After professional sharpening, the wire cutters become what they were when they were purchased.

Self-sharpening of tongs is possible, but requires a machine, polishing and grinding bars. Instead of a machine, you can use a diamond knitting needle with low abrasiveness. Basic Rules:

  • use a mask (glasses), gloves;
  • unscrew the tool before sharpening;
  • work with the machine takes place at minimum speed;
  • sharpening occurs strictly in one direction (the area does not exceed 0.3 mm);
  • observe the sharpening angle (otherwise the tool will lose its cutting ability).

Self-sharpening is not recommended, because. if the diamond wheel is not processed correctly or the abrasive of the polishing bar is not selected correctly, the tool will be damaged. Incorrect sharpening of the corners of the pliers will lead to a change in the cutting edge. When deciding to sharpen yourself, you should first practice on a different type of tool.

Rules for the care of manicure accessories

After each use, the instrument should be cleaned of skin residues and disinfected. The product for home use can be wiped with alcohol. Professional cuticle nippers must be treated regularly with an antiseptic. Mechanisms are treated with a special liquid. Do not use solutions with aldehydes and bleach, they aggressively affect the metal.

You need to store the wire cutters in a closed place (sheath) with the cutting side up, this will avoid premature blunting.

With timely correct sharpening and following simple rules of care, the tool will last for many years.


The choice of good manicure nippers is the primary task of a novice master. Without them, it is difficult to imagine the performance of a classic edged or combined hardware manicure.

What brands should you look at? How to choose the best and what criteria to consider when searching for your ideal model? Consider the types of manicure and pedicure nippers, as well as the rules for their operation.

This is a manicure tool for manipulating the nails and cuticles on the hands and feet. The result of the work of the master depends on their quality and ease of use. Do not forget about the image of the salon - high-quality wire cutters play an important role in this.

According to the purpose, the nippers are divided into 3 main categories:

  • Cuticle nippers or cuticle nippers. They are also called forceps or cuticle tweezers;
  • Nail clippers on the hands - for manicure;
  • Toenail clippers for pedicure.

Cuticle nippers or nippers for cuticles and rough skin around the nails are a must when performing a classic edged manicure, as well as some types of combined ones.

Nail clippers are an alternative to nail scissors. Nippers are larger and stronger than cuticle nippers and are designed for processing hard and rough nails.

Which is better, scissors or wire cutters? Depends on the situation. Manicure scissors with rough nails, for example, age-related, or affected by a fungus, may not cope.

Manicure scissors - types, proper use, choose the best

Pedicure nippers have a larger size and strength, reinforced design. The blade length starts from 15 mm to 21 mm. This size and strength make it possible to work with rough and ingrown toenails, even in older clients, without crumbling or jamming them in length.

Criterias of choice

There are a number of criteria that will help even a beginner choose a quality tool.

Grade and hardness of steel- the material from which the tool is made. Carbon, alloy or medical steel has increased strength and wear resistance. Popular professional tool manufacturers most often offer cobalt-coated stainless steel tools. It makes the wire cutters more resistant to chemical and thermal sterilization.

Surface type: matt or mirror or glossy

head shape: with heel or without heel (extended back of blades)

If there is a strongly protruding heel of the tool, it will be very difficult for a novice master to control the cut. The heel is poorly visible, and with the slightest uncontrolled movement, it can cut the client's skin. Beginning masters can recommend a flat heel or a heel with a minimum protrusion angle.

The length and shape of the connection of the tool handles:

  • return spring
  • 1 or 2 locking plates
  • Spiral
  • hidden connection

The most reliable are tools with a double spreading or helical spring.

The shape and size of the cutting part, the length of the blades

  • Cutting edges must be sharp, even, without dents, chips and notches. In front, the blades should converge at one point and have a sharp nose.
  • The blades should be the same and tightly closed along the entire length without gaps. Checking is recommended to be done with light compression and the spring removed.
  • The shape of the blades depends on the angle of inclination of the cutting edges. The lower heel gives the artisan the ability to hold the tool at a lower angle of inclination.

Blade length varies. The most common options: 7, 8, 15, 16, 20 mm.

Smooth running

The wire cutters should not jerk or jam during the squeezing or unclenching phase.

Comfort in the hand

It is important that the handle does not rest against the central part of the master's hand. It should slightly go beyond the center, come out of the depth of the palm, otherwise in the long run it threatens with increased fatigue and discomfort, squeezing blood vessels and nerves.

Also, the handle can pop out when closed, if its length is not enough for the convenience of location in the hand of the master. This can be tested at the stage of inspection of the instrument, before purchase.

How to work

You should adhere to the following rules for working with wire cutters and tweezers:

  • In order for the tongs to last longer, during operation it is necessary to put them with the blades up, work with gentle movements.
  • Do not throw the tool with a sharp edge down to avoid nicks and scratches.
  • When working, the grip of the tool is carried out with the palm on top, and then the hand turns over.
  • The index finger should be under the undercarriage and the thumb on the undercarriage above.
  • The index finger should not be placed close to the blade, so as not to cut the glove, the skin of yourself or the client.
  • The remaining fingers should be located along the line of the left handle (for right-handers).
  • On the desktop, manicure tweezers should be located with a sharp edge from the client and from the master in order to avoid injury from accidental movements.

an important tool for performing classic edged and combined manicure. How to choose a good instrument? Let's find out in this article!

The manicure master for nippers has many tasks: they perform trimming manicure or remove the length of the nails. Depending on the purpose, the wire cutters can be made of different materials, have different springs and the size of the cutting blade.

The main functions of the nippers- This removal of cuticles, keratinized skin and replacement of scissors at work. At the same time, pedicure nippers have a reinforced design and an enlarged blade from 15 to 21 mm.

How to choose cutters?

  • pay attention to the symmetry of the nippers: the blades should be equally sharp and close tightly.
  • the sharpening of the inner surface of the blades must be at least 3 mm.

The spring element in the wire cutters can be made from a spiral or from two elements. You can remove the spiral from the pliers for cleaning or replacement, and two plates allow you to adjust the stroke of the pliers.

Cutting pliers material

Nippers for skin (cuticles) or nippers for nails are made of medical steel or various steel alloys. The alloy may be different in its properties, for its designation, the manufacturer indicates HRC data.

What do the HRC symbols mean in the description for wire cutters?

HRC- this is the hardness of the alloy. By this indicator, you can find out whether the alloy will hold the cutting part for a long time or will be brittle.

For manicure nippers, a hardness of 40 HRC units is suitable. Nippers made of steel with a hardness of 50-55 HRC units have good hardness and elasticity, are not susceptible to oxidation and rust. When falling on the floor, the cutting edge of the wire cutters will not fall off, but will only bend, which means that in the future the sharpener will be able to restore the wire cutters.Steel with values ​​​​of 58-62 HRC will hold an edge perfectly, but will be fragile.

Manufacturers may use different abbreviations: HR, HRc, HR C, RC— and all these values ​​are on the same scale.

Let's start with the fact that the length of the skins is from 4 to 25 mm. Beginning manicure masters often doubt what size to choose to start with. When choosing the right size, there are a few general principles to keep in mind.

Firstly, if you are not used to any length of the canvas, then you can get used to it and work in any size.

Secondly, you should always start with a larger size, and you can always go to a small length, especially since with each sharpening the length of the cutting edges becomes smaller. The larger size will help build the habit of keeping the heel outside of the cuticle. It will be more difficult to change from a small size to a large one.

Third, you need to take into account what size of blade in your region sharpeners often sharpen, which means it will be easier for you to find where to sharpen your tool in the future.

Now some tips for Ukraine and Russia separately. Cloths of tweezers with a length of 20-25 mm or more began to be made in the metallurgical industrial cities of Ukraine, in particular, as a result of Soviet gigantomania, according to the principle "Soviet watches are the fastest in the world." Large-sized cuticles have their own characteristics in operation and maintenance. The methods of sharpening long blades differ. Sometimes the desire to work with “bigger” and “more authentic” cuticles is justified by the fact that the tool is heavily grinded by “grinders”. But this is not justified. I'll explain why. Cuticles with blades that are too long are more difficult to sharpen and often sharpeners unwittingly or intentionally grind them down to make the tweezers work better. Therefore, we recommend to novice manicure masters In Ukraine, cuticles with a canvas size of 12-14mm. If the soul strives for more, then 15-16 mm (this is with a margin). This is enough for fast and high-quality trimming of the cuticle and in all other respects. An experienced craftsman does not grind the blades when sharpening, but only corrects the cutting edges. In addition, if sharpening is done manually, then grinding off the excess is also extra painstaking work. Now in Russia. For most regions of Russia, the most popular web length is 6-7mm and 8-9mm. Let's take into account that sharpeners in Russia have more experience in sharpening cuticle nippers of exactly this length and it will be easier for you to find where to sharpen the nippers in the future. Therefore, it will be better to start learning with nippers 8-9 mm long, that is, those that are larger for your city. If you plan not to sharpen the tweezers after blunting, but to buy new ones, then it is acceptable that the blade size be about 6 mm. The length of the canvas is 4 and 5 mm only for those who are already used to it and cannot work with others!

Will the heel “cling” if there is a long line of nail clippers?

No, it will not! During work, the non-working part of the canvas is outside the cuticle. Nobody obliges you to work with the whole canvas. The heel can cut the client if:

  1. You are used to working with a short canvas. Or they got used to working with a flat blade, without inclination of the cutting edge - “hatchets”, but took wire cutters with an inclination of the cutting edges. It's not about length, it's about habit.
  2. Cuticle nippers are poorly assembled and therefore poorly sharpened. Blades "walk". One of the blades sticks out a lot and you can't control the cutting.

Conclusion. Choose the length of the cuticles to your liking from 6 to 15 mm And do not be afraid of a larger size.
