Even expensive professional knives made from advanced alloys become blunt from time to time. As a result, they cannot effectively perform the tasks for which they are intended. To fix this problem, you need to choose a sharpener for kitchen knives.

Such a thing is almost indispensable in a modern kitchen, but, depending on the type of knives and user requirements, it is worth giving preference to different types of devices. Our ranking of the best knife sharpeners will help you decide on the best buying decision among manual and electric options, as well as water stones. Let's study the top rating of 2018-2019.

Best manual knife sharpeners

A good manual sharpener for kitchen knives BORNER opens the review. This is the most simple, but, at the same time, quite effective kitchen appliance. With it, you can maintain the sharpness of new ones or bring life to old knives. The universal sharpener for kitchen knives has three zones:

1. sharpening. Pobedite incisors allow for rough processing of the blade. This zone can be omitted if the knife is not too dull.
2. Edit. Diamond cores for finer workmanship.
3. fine-tuning. Ceramic zone that allows you to remove the smallest irregularities.

The classic BORNER sharpener is perfect for all kinds of tourist and kitchen knives, excluding ceramics. The blades are sharpened at an angle of 23 degrees.

Most buyers will find the Tima TMK-001 manual mechanical sharpener quite familiar. This is not surprising, since dozens of other manufacturers use a similar design solution.

The device consists of a main frame, the shape, weight and rubberized base of which provide a comfortable grip and stability, as well as a block with two zones for sharpening. The latter is removable and can be purchased separately. Such an element costs an average of 250 rubles, which is about half the price of the best budget sharpener for simple kitchen knives from Tima.

Sharpener for kitchen knives Mayer& Boch MB-26003

The Mayer & Boch brand is considered one of the leaders in the quality sharpening segment. Kitchen utensils of this brand are always of excellent quality, convenience and, most importantly, attractive cost.

So, the MB-26003 model can be found for about 900 rubles. For this amount, the consumer will receive three sharpening zones:

1. Tungsten is the ideal blade for sharpening knives.
2. Diamond - for coarse sharpening of stainless steel.
3. Ceramic is an excellent rod for removing irregularities and fine turning.

If desired, the Mayer & Boch MB-26003 main unit can be replaced with a new one. But it's not easy to find it for sale. However, this handy sharpener is able to last for many years even with frequent use, because it is made in Germany.

Universal sharpener for knives and scissors RSCHEF S1602 is one of the most interesting solutions in the category up to a thousand rubles. This device has three slots for knives, as well as one for sharpening scissors.

The abrasive surfaces of a quality knife sharpener are metal and ceramic, allowing for coarse sharpening and fine grinding. Other advantages of the S1602 include an attractive appearance, excellent build quality and a well-thought-out design that makes RSCHEF comfortable to hold on the table. On average, for a good sharpening of one knife, the consumer will have to perform 10-15 movements, which is slightly more than stated by the manufacturer.

The best machines and electric knife sharpeners

If you're looking for the highest quality kitchen knife sharpening, then look no further than the Touch Pro Ultra. This is Ganzo's most popular model and is the choice of users who want to sharpen their blades quickly and efficiently.

For convenience, the knife is fixed in the machine at a given angle to ensure uniform sharpening. Then it is processed with the help of stones-strips, which are fixed on the moving part of the Touch Pro Ultra. The consumer can independently purchase the stones he needs, but four elements for grinding and sharpening knives are already included in the package:

• coarse-grained at 120 and 320 grit;
• medium grit with an indicator of 600 grit;
• fine grit at 1500 grit.

The Ganzo machine is made of durable ABS plastic and stainless steel. Touch Pro Ultra is great for all common types of knives, including not only kitchen knives, but also folding and hunting knives.

Multifunctional electric sharpener Luazon LTE-01 Gray 1170133 is an ideal choice for its price. On the Internet, this device is available for about 600 rubles, which is cheaper than many manual devices. The Luazon sharpener is not only perfect for all types of knives (except ceramic and coated models), but also allows you to sharpen scissors and even screwdrivers!

The user can achieve the desired sharpness of the blades in just 10-15 seconds. At the same time, the electric knife sharpener is designed even for serrated blades. The power of LTE-01 Gray 1170133 is 20 W, and the device is powered by a conventional outlet.

Electric knife sharpener Sititek “Mistress 31M”

The first place in the category is occupied by a rather expensive, but extremely effective device - Mistress 31M from the Sititek brand. The average cost of this device is 2500 rubles, but according to reviews of the sharpener from its real buyers, it deserves to spend such money.

The power of the Mistress 31M is 40 W, which allows you to quickly and efficiently sharpen even very dull blades. The best electric knife sharpener in our ranking is equipped with high-strength corundum discs that have many advantages:

• sharpening speed;
• blade quality;
• durability of disks;
• ease of cleaning the device;
• versatility.

Due to the well-thought-out shape, the sharpener lies well in the hand, and the strictly defined sharpening angle ensures not only the professional sharpness of the knives, but also its preservation for a long time. The whole procedure is carried out in two stages:

1. Formation of the cutting edge.
2. Final finishing and polishing of the knife.

This sharpening principle guarantees the elimination of potholes, bumps and chips on the blade.

The best sharpening stones for knives

Sometimes it is not enough just to choose a good sharpener for the price and quality, because it may require additional tools. So, Ganzo D100 cannot be used as a standalone fixture, since it is designed for machines, including the Touch Pro Ultra described above.

The whetstone in question is quite rough (100 grit), so it is suitable for straightening deformed blades, quickly removing gouges on them, restoring severely dull knives, and so on. If you purchase thinner stones for these tasks, then you will have to spend many times more time to achieve a similar result.

Finishing to the final state will require the purchase of additional bars with a smaller grain size. At the same time, keep in mind that under normal conditions you should not try to sharpen blades on stones over one and a half thousand grit. The resulting spiciness will be excessive for the average cuisine.

Fissman is known among consumers due to the high quality of its products and attractive pricing policy. The Danish brand has proven itself well in the segment of whetstones. The model with index 2975 has a 1000 grit and is suitable for fine work with knives.

But, as noted above, knives that are too “killed” should not be immediately sharpened on this bar. If everything is done correctly, then a good whetstone will allow you to achieve a sharpness that allows you to cut paper sheets by weight. However, in this case there are no guides, so you need to learn how to correctly set the angle "by eye".

Knife sharpener Ace ASH105, diamond coating - Ace

If you love to travel and hike, where you often need a sharp blade, then a useful accessory like a travel knife sharpener is a must-have to add to your backpack.

One of the best solutions in this segment is Ace ASH105. This sharpener has two diamond stones, 360 grit and 600 grit. Given that camping knives are usually used for cutting and sharpening branches, cutting food on various hard surfaces and similar tasks, such surfaces will be enough for any user.

If you make excessive sharpening, then it can go astray even faster than a coarser one. In general, according to reviews of the Ace ASH105 stone, we can conclude that this device is very convenient and of high quality, which, with an average price of 675 rubles, are important advantages.

Which knife sharpener to choose for the home

For convenience, we have divided the review of the best knife sharpeners according to reviews into 3 groups. The first includes hand tools. It will not be possible to achieve phenomenal sharpness with their help, but for an average cuisine, the result obtained is more than enough.

In addition, the average price tag of such solutions is a modest 600 rubles, which makes them the best choice for buyers with a limited budget.

From the second category, we recommend paying attention to the machine from Ganzo and the electric sharpener from Sititek. If the cost of the latter is too high for you, then LTE-01, which is in the same price category as mechanical models, will be a good alternative. It also includes stones that close our rating.

And among them there is an interesting model Ace ASH105, which fans of hiking will appreciate.

Even the most expensive branded knife dulls over time, as a result it has to be sharpened. You can do this in the workshop or on your own if you have a special sharpener at home. Such devices are sold in regular stores and on the Internet, but the easiest way is to buy them on Aliexpress, where they are much cheaper. You just need to decide on the purpose for which the tool is purchased, because there are no universal models. On the Chinese marketplace there are such options:

• manual mechanical sharpeners - suitable for kitchen knives, they sharpen the blade quickly, but after that the knife dulls just as quickly;
• pocket sharpeners for tourists - compact models of a mechanical type that are convenient to take on a hike;
• whetstones are effective tools that require experience with a whetstone;
• musats for straightening knife blades - carefully align the cutting edge, resemble a file in shape;
• electric sharpeners - work quickly and efficiently, automatically determine the sharpening angle, but are expensive;
• sharpening systems with and without fixing the blade - machines in which you can set the desired angle.

The ranking includes models from a variety of Chinese manufacturers. They differ not only in the principle of operation, but also in the type of abrasive materials. All these devices have received good reviews from real users. They are united by the best technical characteristics, excellent brand reputation and high work efficiency.

The Best Classic Knife Sharpeners from AliExpress

The category presents the best mechanical tools of the broaching type. They are two bars or plates set in relation to each other at a certain angle and hidden in a plastic case.

Reviews about this product on Aliexpress are mostly positive, but not without mentioning the shortcomings. Users write that knives with a small blade are inconvenient to mount in the holder. Also, many complain about the low quality of the stones and advise buying diamond ones.

The best whetstones (whetstones) from Aliexpress

No matter how actively progress progresses, there will always be lovers of sharpening knives in the old proven way - with the help of whetstones. This is the most effective, but not too easy, method to sharpen blades. On AliExpress, you can buy sharpeners of this type, made mainly of artificial stone.

4XINGCHENG CF083-01

The optimum ratio of price and quality
Price on Aliexpress: from 263 rubles.
Rating (2019): 4.6

The diamond coating is reliable and wear-resistant, in the seller's assortment there is an option with only one grit level - 1000 Grit. It is suitable for sharpening and finishing the blade of hard steel blades. On the reverse side there is a sticky surface that prevents the bar from slipping.

The reviews recommend slightly wet XINGCHENG CF083-01 before use. Thanks to this, the procedure for sharpening the knife will be easier and faster. Among the shortcomings, users mention a too thin plate, it is difficult to hold it in their hands. To correct this inconvenience, you can glue the stone to any surface, make a handle or stand for it with your own hands.

3 Sy Tools Ruixin Edge Apex

The most popular model on Aliexpress
Price for Aliexpress: from 256 rubles.
Rating (2019): 4.7

Ruixin EDGE Apex from Sy Tools is the record holder for the number of orders and positive reviews on Aliexpress. This nondescript pebble helps to restore sharpness to even the oldest and crooked knives. Surface grain is uniform, no cracks, chips or scratches. The stand is made of plastic, the bar itself is metal with diamond coating.

Users recommend ordering multiple grindstones at once to get a discount. It is convenient and profitable, especially since there are a variety of grit options in the assortment: from 80 to 2000 Grit. During transportation, the bars do not crumble, as the seller packs them qualitatively and firmly. The only drawback is that some buyers believe that the graininess is slightly overestimated. For example, a 2000 Grit tool looks like a maximum of 1500. Otherwise, the product is fully consistent with the description, with its help the blades are quickly sharpened from all sides.

2 Aihogard JJ2856

Best travel knife sharpener
Price for Aliexpress: from 380 rubles.
Rating (2019): 4.8

There are always special requirements for camping options for sharpeners. They should be light, compact and easy to use. Equally important is the price - it would be a pity if an expensive instrument is lost during a trip. All these criteria are met by the Aihogard JJ2856 whetstone. It is light and compact, weighs no more than 60 g, dimensions - 125 * 32 * 16 mm. The device comes in a convenient plastic case that folds like a penknife.

For a ridiculous price, buyers from Aliexpress get a good whetstone with an abrasive coating of two types. The handles seem flimsy in appearance, but they can withstand the load, judging by the reviews. But their color in reality may differ from the photo on the seller's page. But this does not affect the functionality of the travel knife sharpener. It's hard to find a better option for a hike for the money.

1 SURVEN Sharpener

Wide area of ​​stone. Non-slip stand
Price for Aliexpress: from 1105 rubles.

Those who have experience with stones will be able to sharpen the edge of knives, scissors, shovels, hoes and axes in a matter of minutes. To do this, there are two types of abrasive surfaces with a grit of 1000 and 400.

The reviews claim that with this sharpener and straight hands, you can get the best result. Buyers express dissatisfaction only about the rim of the stand. But it wears off over time and no longer causes inconvenience. The dimensions of the diamond stone are 152*63 mm, including the stand.

A really interesting knife sharpener, if someone’s hands are “not sharpened” or just too lazy to sharpen by hand, but you want to have a sharp knife.
If you immediately start with the shortcomings of the sharpener, then it is, in fact, one! It has a fixed sharpening angle :)
Well, who is interested in reading about the advantages and considering in more detail, let's move on ...

Cheap, yes, I agree! But a good set for manual sharpening costs slightly less (or the same), and there you need to apply some skill and dexterity, anyone can do it here (even a child and a blonde housewife - I don’t mean hair color)

You need to understand that with such a sharpener it is possible to sharpen not any knife.

Basic shapes of kitchen knife blades

1 - wedge-shaped descents from the butt itself, the traditional cutting edge. One of the most common shapes for kitchen knives. Very easy to cut thick layers of material;
2 - wedge-shaped descents starting from the butt, which directly form the cutting edge. A fairly common form, however, in the process of regrinding, it almost always turns into type 1. Due to the large area of ​​​​descents at the point, the bar is “oiled” with foreign metal, so it is much more difficult to sharpen such a knife correctly than option 3. Of course, after the knife point, polishing of the side surfaces is required, if its appearance is important to the owner;
3 - flat blade, wedge-shaped slopes forming a cutting edge, starting from the middle or two-thirds of the blade width (counting from the butt). A very characteristic shape for many universal national knives, especially Scandinavian ones. It is often found on sale, it is very easy to sharpen, since the planes of the descents set the sharpening angle, while having a relatively small area;
4 - flat blade, wedge-shaped slopes, traditional cutting edge. The most common profile option. Allows you to vary the angle of sharpening. The knife is strong enough, it cuts relatively easily;
5 - flat blade, wedge-shaped descents, the cutting edge forms a double wedge. If in option 4 the wedge of the cutting edge is single, then in option 5 part of the material is removed from the corners between the descent and the edge. As a result, when cutting thick and dense materials, the knife experiences less resistance. It almost never occurs in factory products, but it can be recommended as the main one for people who have mastered the manual sharpening of knives;
6 - flat blade, lenticular concave descents. The angle of the cutting edge is formed by the continuation of two planes drawn from the edge between the blade and the descent to the point. This sharpening is also called "razor" - it is typical for dangerous razors. It is easily sharpened and corrected - the line between the blade and the trigger serves as a “guide” for determining the sharpening angle. The descents themselves can start almost from the butt. The knife cuts relatively thin materials very well, worse - thicker ones (due to the presence of an edge). Due to the massiveness of the butt or the blade itself, the knife has significant rigidity;
7 - "chisel" or one-sided sharpening. It is typical for national Japanese knives. Relatively easy to sharpen if the edge is not severely damaged. Minus - the knife is intended only for one hand, the bevel should be on the side of the working hand. In this case, a right-handed blade is depicted (assuming that we are looking at the blade from the side of the handle);
8 - actually represents option 3, only the angle of the cutting edge is such that there are no slopes as such. The shape of the blade is typical for cheap Chinese fakes for branded knives, as well as for all kinds of chopping tools;
9 - "animal", or "bullet" sharpening. A characteristic feature is convex lenticular descents. It does not cut very well, it gets stuck in the material, but it cuts beautifully. Of course, such knives are more difficult and more expensive to manufacture and sharpen than option 8.
Cutting edges are highlighted in red.
Most high-quality kitchen knives have slopes that start almost from the butt and a small, thin cutting edge. Accordingly, the sharpening process is precisely the formation of the correct cutting edge. Its ideal shape is a wedge (option 3), or a two-stage (double) wedge (option 5).

There are four holes in the disc block, the first two are for coarse sharpening “1”, the other two are for finishing. Each of the holes for one side of the knife. First sharpen one side of the knife, then the other.
There is no need to press hard, just pull on yourself. After the appearance of a small uniform edge on the blade (felt with a finger), repeat the procedure with the other side of the blade (in the adjacent hole "1").
Rough sharpening is needed for knives that are in poor condition - removing blade defects - chips and damage, as well as setting the angle if you previously had a different knife. If the knives are in adequate condition, then it is enough to sharpen with a fine abrasive, rough sharpening is not required for them.
For sharpening, there is no need to maintain angles. The whole procedure takes from half a minute to a minute. It sharpens knives very well (really), and even our “nameless” knives after sharpening are not inferior to brands (at least for a while;)

You can sharpen not only metal, but also ceramics! When working, the sharpener makes noise, but not very much.

From time to time the sharpener needs to be cleaned:
- rotate the sharpening block clockwise until it clicks.
-take it out of the common block.
-remove the cover of the guide knives and shake it out.

A small study on the quality of sharpening household knives

In addition to the one described in the review, we will consider a couple more household ones, with manual sharpening.
The test subject will be an old knife - by the beginning of the experiment, pretty "tortured".


I immediately apologize for the “dirty” knives, they have been lying around for a long time - I didn’t pay attention when photographing, but the enlarged photos turned out to be creepy :)

I will make a mark on the knife blade with a marker - we will consider a specific place. As you can see in the first photo, the knife is not only blunt - it has a notched/damaged blade.

The first knife sharpener, the most common option, has two holes with inserted stones of different grain sizes.



Sharpens the knife as it is pulled through the stone, removing the metal along the surface. In fact, after sharpening with this knife, it seemed to me that the blade had become even blunter :)
This blade was BEFORE using this sharpener

This happened after her.

At the same time, it intensively removes metal from the blade, in other words, it does not sharpen as much as it spoils the blade.


This is partly visible on the edge - the damage that was originally on the blade is gone. It can only be called a knife with a big stretch. Probably the stone has worn out, and now the knife cutter removes metal not only from the side surface, but also from the edge ( well, she didn’t sharpen before).

The next, outwardly similar, knife from Ikea. She is, surprisingly, sharpens knives quite tolerantly.

The “reason” for more or less acceptable work is the mechanism for sharpening it. When pulling the knife, the discs rotate, which sharpen not along the surface, but at an angle.

The photo shows the result of her work.
The edge is sharpened, after the work of the previous knife sharpener.

And more correct sharpening is visible on the side surface

And finally Samura...
Pre-sharpened to 600 grit (holes "1")

And after fine-tuning to "2"

Practically "strictly according to science";)

An electric sharpener is certainly not cheap, but the savings in time and effort are enormous. And most importantly, the result is excellent!

After writing this review, I “chopped” shank for my lunch, the old knife (after the new sharpener) cuts great!

By the way, to all owners of any version of the described sharpener, here for $ 12.17

And I also got it at an even lower price, but the truth confuses its name on the seller’s page (or rather its interpretation) - I didn’t dare to post a review with such a name, “they will be banned”;) Read the beginning of the name, you will understand :))) )

Good luck everywhere, run to the review;)

Every person who loves to cook knows the importance of a well-sharpened kitchen knife. Only a sharp knife can beautifully and thinly cut a variety of products. With a dull knife, you will not be able to achieve high-quality cutting. Yes, and the pleasure of the process of preparing a culinary masterpiece will be hopelessly spoiled.

It follows from this that the process of sharpening a kitchen knife must be approached with special attention. It includes several main steps. By the way, what kind of sharpening should be directly depends on the material from which the knife is made, how many cutting edges it has, how it is used in the cooking process. As a rule, knives are sharpened with various materials, and, therefore, certain skills are required for this. So, the sharpening process can be of different types:

1. Directly the process of sharpening the blade of a kitchen knife when it reaches the desired degree of sharpness. It should be borne in mind that a knife that is used to cut rough materials or fabrics can be simply sharpened and that's it. All defects in the form of scratches and the like will only enhance the "sawing" properties of the kitchen knife. However, its sharpness will not be durable, so you should consider purchasing a sharpener that can withstand frequent use.
2. Editing process. Dressing is needed when "waves" form on the edges of the knife blade. In other words, the edges of the blade can be wrapped in one direction or in different directions. In this case, edge alignment is even more important than sharpening. This is followed by light sanding.
3. Regrinding process. It becomes necessary when the blade has chips, breaks and other defects. Resharpening is also needed in cases where the user wants to change the angle of sharpening the blade.
4. Finishing process. Fine-tuning includes grinding, with which you can completely eliminate minor deformations and simply polish the blade. A knife that has been honed retains its cutting ability longer. Moreover, it is considered safer.

Here's what you need to know about the process of sharpening kitchen knives. This knowledge will allow you to achieve maximum sharpness of the blade.

So, with the sharpening process, everything is very clear. Now let's take a closer look at what tools you can use to sharpen a kitchen knife. In other words, we will talk about varieties of sharpeners.

So, knife sharpeners are different. Starting from the most primitive and ending with the most progressive models, which allow you to achieve maximum sharpness of the blade with minimal effort.

All sharpeners for kitchen knives are divided into the following types:

1. The simplest type of sharpeners are keychain sharpeners, which are mobile devices. These sharpeners come in different shapes, colors and sizes. It is convenient to have such a sharpener with you, especially when hiking or fishing. It has an original design. Such a sharpener can look like a standard pocket keychain, or it can even be made in the form of a bank card.
2. Folding sharpeners of the "balisong" type got their name from the region where they were first created - the Balisong district in the province of Batangas, in the Philippines. By the way, the first folding knives were invented here, and folding sharpeners, which are rectangular, in the form of a rod or an awl, were also created according to their type. This sharpener can be used to sharpen any blade. A sharpener of this type is also convenient to use in camping conditions, traveling and fishing, as it has a compact size and gives a fairly high-quality result, restoring the sharpness of a kitchen knife.
3. The most primitive and simple device used for sharpening knives is a whetstone. In most cases, it has the form of a bar, cylinder, disk or rod. The shape depends on the imagination of the manufacturer. In some cases, a whetstone may have a handle, backing, and body made of wood or plastic. There are double-sided grindstones that have different abrasives. In general, such a sharpener is also considered mobile, compact and unpretentious. It will allow you to cope even with a very dull knife in any conditions.
4. There are also mechanical sharpeners. Usually they are stationary and have a fairly large capacity. With the help of such a sharpener, you can set the required sharpening angle, set the appropriate abrasive material, and so on. Mechanical sharpeners are classified as professional devices that require certain skills and experience. In general, it is universal and quite convenient to use, but in order to use it correctly, you will need to learn.
5. The most modern are electric sharpeners, the design of which can be both bulky and quite compact and neat. Typically, such devices are used in catering establishments, where knives must always be sharp.

However, this does not mean at all that ordinary housewives in the kitchen do not use electric sharpeners, and we will talk about them in more detail.

What is an electric sharpener

This device, as a rule, has several grooves or recesses. It is through them that you will need to draw a knife blade several times. Inside the groove there are special discs that have a different coating. As the discs rotate, the process of sharpening the blade takes place. In order for a kitchen knife to be sharpened qualitatively, it will be enough to swipe the blade two to three times.

In general, there is nothing supernatural in this device. It works from a network of 220 watts, and it would be much more accurate to call it a grinding station, which is equipped with an electric drive. To make the sharpener work, simply plug it into the network and run the knife blade through the grooves several times.

Electric sharpeners have a function that allows you to select the sharpening angle according to the type of blade surface. In this case, as a rule, it means a system of polymer or magnetic guides that allow you to maintain the desired angle in the process of sharpening a kitchen knife. Naturally, this allows you to expand the list of knives that can be sharpened with an electric sharpener. Also, the device can be equipped with special slots that allow you to sharpen the edge of the blade on one side. It is worth noting that this unit costs a lot, but the high price justifies itself. Especially when you consider that the device allows you not only to quickly sharpen a kitchen knife, but is also safe, versatile and convenient.

In general, an electric knife sharpener is a portable device that has a compact size and is powered by a mains. Its body is made, as a rule, of high-quality plastic, which is equipped with a special pallet. It will crumble chips, which are formed in the process of sharpening knives. It is worth adding that metal electric sharpeners can also be found on sale.

With an electric sharpener, you can sharpen a knife in just a few minutes. The range of these devices is quite huge. They are quite small, which are intended for home use. Also on sale are professional devices that allow you to sharpen several knives at once. They usually have several holes that are designed for different types of blades. It is worth adding that with the help of such a sharpener you can also sharpen scissors and even screwdrivers.

The equipment of the electric sharpener may be different. For example, the device can be designed not only for sharpening a dull blade, but also for polishing it. Not many people know that regular polishing will keep the knife blade in working condition without resorting to the sharpening process.

An electric sharpener will not take up much space in the kitchen, even if the room is small. The presence of this small unit will get rid of the problem with blunt knives, and kitchen knives become blunt very often - this is a fact proven by many housewives.

And that is why it is worth understanding in more detail what you need to pay attention to in the process of choosing this device.

What to consider in the selection process

The main advantage of electric sharpeners is that even women can use them, since the sharpening process itself does not require significant effort. However, when choosing this device, the following nuances should be considered:

1. Manufacturing firm. This is important, as sharpeners from well-known brands are of high quality and long service life. In addition, a proven brand also provides a guarantee for the product.
2. Unit power. Yes, electric sharpeners come in different capacities. For domestic use, low-power models that have a low cost are suitable. For use in a professional kitchen, you should choose a more powerful sharpening. Naturally, the cost will be much higher. It should be noted that the processing speed of the blade depends on the power.
3. Functionality. In this case, the number of grooves for sharpening is implied. Budget models usually have only one groove. More expensive ones may have two grooves or more. The simplest devices are designed only for sharpening a universal type knife. Others may additionally have slots for straightening and polishing the blade and more.
4. The material from which the body is made. This factor is also important when choosing an electric sharpener. Usually it is made of plastic, but there are also metal models. They are more durable. The metal electric sharpener will not break from falling or impact.

Considering all these nuances, you can choose a quality electric kitchen knife sharpener that will last a long time.

Finally

It is worth adding that electric sharpeners are not at all suitable for sharpening knives that are made of ceramics. Rather, you can use them for ceramic knives. However, you should not think that the electric sharpener will return the edges of the ceramic knife to their former sharpness, but at the same time it is able to even out the chips.

In general, an electric sharpener is a useful device to use in the kitchen, as a kitchen knife is used for cooking more often than any other item. Therefore, it quickly loses its sharpness. It follows from this that you will have to sharpen the blade often, which means that the need to purchase an electric sharpener is fully justified.

Video. How to choose an electric knife sharpener

Before you start choosing a sharpener, you need to determine the following points:

1. Blade type of your knife(s)

Knives with a straight blade and double-sided sharpening can be sharpened on most of the various sharpening tools.

Knives with one-sided sharpening require special tools - suitable, , or for Asian knives.

Serrated knives (with a file) are sharpened or on with triangular sharpening elements. Editing of such knives can be carried out in a special groove of some models . Editing of such knives can be carried out in a special groove or at the stage of polishing (with ceramic discs) of some models.

Knives with a wavy edge on one side only , are sharpened with small ones, suitable in diameter to the notches on the blade. Working hooks are sharpened on diamond or ceramic blades.

Fishing hooks, needles, arrows are sharpened on manual sharpeners with a special recess for pulling the tool.

2. Type of sharpener

Determines the sharpening level. It is necessary to pay attention to the following characteristics of sharpening tools:

• Instrument size
• Your skill level
• Device portability
• Purpose

Some general purpose sharpeners can sharpen almost all types of knives and tools, while others are designed for specific uses only.

So, for example, you can sharpen a variety of knives, as well as tools. At the same time, you will not be able to sharpen bread knives or scissors. Conversely, serrated blades are great for sharpening serrated knives, but are not suitable for working with tools.

The preset sharpening angle will help the beginner not to “fill up” the knife, while the experienced grinder will be able to set any angle on the cutting edge of his knife on the stone. So, analyze all types of sharpeners and choose the one that suits your experience and goals.

:

• Sharpeners with a fixed sharpening angle.
• Suitable for quickly sharpening your usual set of knives with a minimum of effort and skill.

:

• Suitable for those who do not mind spending more time and effort, but want to achieve the perfect cutting edge. Requires a certain skill or at least additional. device: sharpening angle holder.

:

• Ideal for everyday light and quick dressing of knives. Not suitable for sharpening heavily blunt knives.

:

• Allows you to set any sharpening angle for a knife or tool, but is somewhat difficult to install.

:

• Ideal for sharpening heavily damaged knives or knives made of very hard steel. A great option if you need to sharpen a large number of knives.

3. Abrasives

Exist four main types of abrasives : Arkansas stones, carbides, ceramics and diamond.

Each group has its own unique characteristics and capabilities. It doesn't matter which of the abrasives you choose, each of them gives a good result.

The choice comes down primarily to how quickly and how much you want to remove metal from the cutting edge.

Diamonds:

• Diamonds- the hardest substance known to man, therefore sharpeners with diamond grit abrasives are the fastest, most wear-resistant and very effective. They are quite aggressive and quickly remove metal from the cutting edge.

Carbides:

• Very aggressive material that quickly removes metal from the blade, ideal for restoring the cutting edge in 3-4 pulls.

Ceramics:

• Removes the minimum amount of metal. Excellent for the lapping and polishing phase.

Arkansas stones:

• Natural stone mined in Arkansas (USA) removes the minimum amount of metal. On such stones, knives are polished, bringing the cutting edge to a mirror surface and razor sharpness.

We advise you to actively consult with sellers for the correct selection of a sharpening device, because the quality and life expectancy of your knives depend on it.
