Why do you have to sharpen knives?

There are several reasons why blades lose their sharpness:

• The most common reason that cutters quickly become blunt, sadly, is the poor quality of the metal from which they are made. Today, the bulk of the goods comes to us from China and, unfortunately, quality often suffers. We are glad that we buy a thing cheaply, but, as a rule, this joy is short-lived - until the first breakdown.
• Another reason is the formation of small chips in the place of contact of the movable and stationary cutting elements. Despite the fact that we mainly twist soft foods, such as meat, it comes across small bones and tendons that fall on the cutting surface of the knife. This leads to a gradual blunting of the blade.
• With improper use, the metal from which the knives are made begins to oxidize and rust.

Important! If you notice that your meat grinder has started to “chew” meat, then it’s time to sharpen the knives.

Today you can easily buy a new knife for any type of meat grinder or grind an old one in a workshop. But this requires additional costs, in addition, there are situations when you urgently need to twist something, the process is started, and your meat grinder refuses to cooperate.

Important! The knives of any meat grinder have the same shape, the only difference is how the parts are scrolled - manually or by an electric motor. Therefore, the methods of sharpening knives are suitable for any type of device.

How to sharpen knives?

There are several nuances that need to be considered when sharpening knives for a meat grinder:

• Two knives are involved in the product twisting - this is a fixed disk with multiple holes and a four-blade cutter (a rotating part, due to which the main grinding occurs). You need to sharpen both.
• Before sharpening, the parts must be thoroughly washed and dried.
• Previously, it is advisable to treat the knives with vegetable or sunflower oil and leave for several minutes. Do the same with the tool that you will use. This will reduce the risk of scratches and chips.
• When sharpening, try to press the center of the part to the tool - this will ensure a more uniform removal of the metal layer.

Important! Many manufacturers of modern electric meat grinders promise us a magic unit, in which the knives do not blunt and self-sharpen. But this is just an advertisement, since there are no knives that will remain perfectly sharpened throughout the entire service life of the devices. Well, or this device will have a very short life.
