Meat is a soft substance, but it often comes across small cartilages and durable veins, which contribute to the gradual rounding of the cutting edge, and it becomes dull.

Rules of performance

Moving cutting tool always works. paired with fixed grille, which has holes all over the plane, and you need to sharpen them together. This part rotates with the screw and the four blades begins to grind the product, which penetrates through the holes under pressure. In this way, a grinding difference is achieved, since several gratings are used: with small or larger perforations.
During sharpening, you need to pay attention to each edge of the blades, so that they have a sharp edge of the cutting edge.
First you need to prepare all the necessary materials in order to carry out the entire process with high quality and follow the basic rules.
- Check the surface on which you will sharpen the knives with thick metal ruler - Attach and make sure that there is no clearance. Put a paper or a circle on the table, fix it tightly. Under the sandpaper is better to put a piece of plexiglass for better horizontal position.
- Lubricate the blades and the polished surface of the grill first. sunflower oil and leave for a few minutes. The surfaces on which the sharpening will be performed should also be lubricated for better contact and the formation of a kind of abrasive paste that protects the knives from minor scratches. When sharpening on a special water grinding wheel, moisten it with water, not oil.
- To treat the entire surface evenly, use wood clamp. It is necessary to press in the center of a knife or a lattice, to make circular motions evenly, with little effort when pressing on a tree.
- After sharpening a four-blade knife, it is necessary to sharpen the grate, the edges of its perforations also wear out during work.

So that the stone does not move on the table, under it enclose dense matter. Take a knife and start doing rotational movements clockwise.
