The problem of skin irritation after using an electric shaver is familiar to many men. It occurs, as a rule, after a certain time of use of the appliance and is accompanied by discomfort during shaving. The reason for this phenomenon is not the quality of the razor or skin features. It is simple for the device’s knives to lose their original sharpness over time, even if the manufacturer positions them as self-sharpening. But you should not rush to purchase new ones or contact sharpening specialists. Everything can be done independently.

Sandpaper Method

One of the most affordable ways to solve the problem is to use ordinary sandpaper. This will require:

  • a sheet of sandpaper 1200 microns;
  • a sheet of sandpaper 2500 microns.

In both cases, a square piece of 100 to 100 mm is suitable. It is desirable that the base of the sheet is not soft.

The action algorithm is simple. To begin with, you need to remove the body of the shaving head with safe blades from the device and get the rotating knives. After that, they should be laid out on a piece of sandpaper with a larger grain. Next, combining the knives with the shaver shafts, you need to turn on the device for about 20 seconds. This will provide a rough sharpening of the blades. In this case, you do not need to press the razor for a more snug fit of the knives to sandpaper. Enough will be the effort that creates the weight of the device itself.

After that, you can proceed to the fine sharpening procedure by performing similar actions lasting 15 seconds using sandpaper with a grain size of 1200 microns. At the end of the procedure, the knives must be cleaned with a soft cloth and the razor must be collected.

GOI paste method

An equally affordable and effective way to restore the sharpness of the blades is to use GOI paste. This abrasive material is used for grinding and polishing a large number of materials, including metal. The action algorithm can be divided into 3 stages:

  1. Preparatory. At this stage, a sharpening solution is prepared on the basis of GOI paste. To do this, mix a small amount of paste in butter. For better mixing, a few drops of solvent can be added. The result should be a mixture that resembles jelly in consistency. The amount of solution should cover the bottom of the container used for mixing by a few millimeters.
  2. Direct sharpening. Unlike the first method, it is not necessary to disassemble the electric razor and remove the knives. It is enough just to immerse the appliance in the prepared mixture and turn it on for 2-3 minutes.
  3. The final one. At this stage, it is necessary to carefully clean the blades from the remnants of the solution with a napkin.

Glass and screwdriver method

An alternative to the first two methods can be sharpening knives on glass. Fundamentally, the method is identical to the sandpaper option. But given the hardness of the glass, for high-quality sharpening, the rotation of the knives is attached using a screwdriver. A prerequisite for this is the use of the tool in reverse rotation (reverse) mode and at low speeds. Otherwise, the blades become dull even more.

For reliable transmission of rotation from a screwdriver to a knife, it is recommended to use a trihedral bit. High-quality sharpening time for one element is 4-5 minutes with a light touch.

Thus, using any of the described methods for sharpening electric razor knives, you can save a significant amount of money in comparison with the acquisition of new cutting elements or by contacting specialized workshops. As a result, the shaving process will become enjoyable and economical.
