The myth of the supposedly self-sharpening knives broke very quickly... About life. This is not surprising, the laws of physics, the laws of physics have against them, so to speak, powerless even marketers. If the home is not sharpened knives, if you remember the famous bard, nothing good. Today Editorial HouseChief.ru help solve the problem of blunt blades and tell how and what can be properly sharpened knife at home. We will introduce its readers with different types of devices for sharpening knives, will talk about their effectiveness, as well as teach you how to make a simple sharpening machine at home.

Types of devices for sharpening blades

Whetstone for sharpening knives, probably - the first of its kind. Simple, and, most importantly, affordable tool copes with its task for many millennia.

So far the classification of machine depends on this, once the uncontested winepress. According to the type of abrasive material may be:

• bars;
• grindstones.

Drive type:

• hand;
• electrically driven.

In situ:

• home;
• professional.

However, in the modern world can be a whetstone to sharpen except that a simple hunting knife. In other cases, the quality will be poor. Additionally, the stone grind only soft metals, if the cutting portion of the blade has a hardness greater than 55 HRC, improvised means it is not sharpened.

Important! Every blade type has its corner edges. And during sharpening it is necessary to keep the entire length of the work surface of the product.

Some types of modern grindstones are used to this day. An example of this natural stones - Japanese water stone (we showed it in the photo above), or the American "Arkansas". Master grinders even hold special workshops on sharpening knives using natural stone. Interestingly, the treatment process before it is soaked in water, sometimes with soapy water, and dried after use. The whole process resembles the sacrament for the initiated. Therefore it is not surprising that these rocks are too expensive, and in most sharpening devices used artificial abrasive surface.

Stones for sharpening knives

This artificially machined bars coated abrasive, which are suitable for both manual sharpening tools and instruments, and for kitchen knives.

Bars, depending on the material from which they are made can be different degrees of wear resistance and graininess. Consider the main types of materials used in the manufacture of whetstone:

1. natural stonesSuch novakulita or Japanese water stone. Working with such a tool is not very easy. They require certain skills and craftsmanship.
2. diamond (Diamond-coated) - can be of various shapes and graininess. Wear-resistant. Reasonable price.
3. ceramic. Refer to the more modern look of the bars for sharpening. Combine the fortress of the diamond coating to the hardness of natural stone.
4. artificial: Corundum or carbide. Quickly grind abrasive, characterized by low quality and the same price.

Artificial abrasives are created by mixing different fractions of diamond powders, as well as oxide and carbide.

Important! Of great importance in this case is a material used for bonding the breed, and the percentage of all elements. The stronger and better composition (this applies to the particles themselves), the more resistant to abrasive grindstone.

And there are two kinds of elements ligament - galvanic ligaments and soft. In the first case, crystals are bonded strongly to the surface of a base made of a nickel alloy. In fact, the crystals are very thin layer on the bar. Soft bunch - a chaotic arrangement of binders and abrasive elements. The second type is less durable.

Grindstones for knives

If we talk in more detail about the grindstones, you need to describe the main varieties, used in such instruments, it helps to understand in detail the process and understand how to grind knife properly. But before we talk about them, not to mention about the stages of sharpening that will be in this context, play a decisive role in the description of the different materials and tools.

Stage	Description	Illustration
sharpening	Recovery blunt edge sharpening angle without correction.
tweaking	Grinding edges with fine abrasive grains.
correction	Polishing of the bevel of the cutting edge and ceramic pencil GOI paste or a leather strap.
Regrinding (sharpening deep)	Complete recovery of the desired sharpening angle, the geometry of the profile of the blade and removal of chips on the edge. Most often, this work is carried out on special machines.

Let's move on to a description of the main options grindstones.

Japanese water stones Waterstone

Applied equally effectively at all stages of sharpening. There are artificial analogues (ceramic-based), but professionals use the original, natural materials. Stones require special care, because the most important rule of the master - perfectly smooth surface of the grindstone.

"In order to check the degree of uniformity of stone, use a simple method. Moisten the timber and place it on a sheet of paper on a flat surface. The imprint will allow you to assess the degree of flatness of the stone. "

Novakulity or "Arkansas", "Turkish", "Belgian" stones - natural slates and chalcedony interspersed with tiny particles of garnet and quartz. Today used as natural stones, as well as their artificial substitutes.

Important! Stones work only in combination with a special lubrication oil. Extraordinary and unique stone structure allows to use them at different stages of processing.

Musat for sharpening knives

Musat - a kind of file, usually mounted vertically. A special feature of this tool is that the surface it is magnetized, and therefore, you will not roll in flour metal.

Each variation has its own advantages. For example, a round Musat weighs a bit, but the oval sharpens better, as its facets provide more complete contact with the treated surface. Tetrahedral - more versatile, there can be more qualitatively modify the desired sharpening angle.

Household hand tools for sharpening knives

About versions and varieties of hand tools used in everyday life, we can talk for hours. This is the usual domestic mini-sharpeners, known to almost everyone, and the more specific devices with a polishing wheel.

The easiest way to work with mini-sharpener, which control the course of the tool. In this case, the degree of sharpening depends on the efforts being made by people.

Domestic electrical machines for sharpening blades

Electric grinding machine more comfortable. Work with them saves time. Most of these machines have different driving modes, which are regulated by switches.

Typically, such machines are compact, safe, simple and reliable, since all wheels are hidden inside the casing. In this case, the sharpening angle is regulated by a special spring, which eliminates errors in sharpening.

Professional manual sharpeners for knives

Professional hand tools Joiner's a bit like a vise. The subject of sharpening, in fact, the knife is clamped by special clamps.

Sam grinder is set to focus. It is very important to fix the machine and to avoid slippage of the device during sharpening.

"The blade of the knife should be sure to be wet. You can use special oils or grinding lubricant. "

The next step - the choice of the sharpening angle. Here we focus on the above table, and take the band to and from. Do not forget, the less sharpening angle, the faster the blade becomes blunt. For a beginner it will be difficult to sustain the same angle. In order to successfully pass this stage, it is important to hold the knife with both hands.

The process of grinding does not differ from the manual sharpening method. The only difference is that in this case, is not wetted by the blade, and the grinding disc. Normally this happens automatically in the machine, which we discussed above.

Common mistakes when sharpening knives with their own hands

Everyone knows that better prevent errors than their later corrected. That is why the revision HouseChief.ru prepared a list of the most common missteps beginners during the sharpening of knives:

1. Wrong sustained level of sharpening angle.
2. Regrinding of the blade. It occurs when excessive pressure on the sharpener blade, because of which it may be damaged or even break.
3. Sharpening tool unprepared or worn grinding disc.
4. Using Musatov at all stages of work. As we remember, Musat used for finishing the cutting edge.
5. Using fine grit abrasive.

All these subtleties is important to consider at the stage Works. To learn how to properly sharpen a knife bar, see this video.

Making your own hands the machine for sharpening knives

Buying a ready machine for sharpening of knives is not always necessary. For domestic use can make it with your own hands. Whether mechanical or electrical machine, you will create, guided, as mentioned earlier, on existing schemes and drawings.

What are necessary tools for making their own hands nozhetochki

For the manufacture of simple machines, we need:

1. A piece of chipboard 10-12 mm thick. You can use the old furniture.
2. A piece of wood.
3. Metal rod M8 or M6.
4. Sheet steel 1 mm thick.
5. screws or nuts and washer corresponding to the diameter of the pins used.
6. Abrasive material.
7. Hacksaw or jigsaw
8. Screwdriver.
