Why do I have to sharpen knives?

There are several reasons why blades lose their sharpness:

• The most common reason that cutters are quickly dulled, sadly, is the poor quality of the metal from which they are made. To date, most of the goods come to us from China and, unfortunately, quality often suffers. We are glad that we are buying a cheap thing, 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 moving and stationary cutting elements. In spite of the fact that basically we twist soft products, for example, meat, small pits and tendons come into it, which fall on the cutting surface of the knife. This leads to a gradual blunting of the blade.
• In the event of misuse, 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 sharpen in an old workshop. But it requires additional costs, in addition, there are situations when you need to urgently 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 difference is only in how the parts are scrolled - manually or by an electric motor. Therefore, the methods for sharpening knives are suitable for any type of device.

• Clean the parts thoroughly before drying and dry them.
• Preliminary knives should be treated with vegetable or sunflower oil and leave for a few 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 against the tool - this will ensure a more even removal of the metal layer.

Important! Many manufacturers of modern electric meat grinders promise us a magical unit, in which the knives do not blunt and self-sharpen.

Well, or this device will have a very short service life.
