With this note, I would like to begin a series of materials on the site dedicated to one of the most pressing topics in the Russian knife world - knife sharpening skills for beginners.
We will include as beginners not only those who have just become interested in the topic of knives and bought their first good pocket or kitchen knife, but also many people who cannot afford full hours of time spent sharpening knives for various reasons, but to sharp knives I'm not indifferent either.
Nowadays there are a lot of materials available on the Internet on the topic of sharpening knives, but many of them are quite heavy to study and do not briefly answer the simple everyday question of “what and how.” Therefore, I will try to answer the most important questions on one page. frequently asked questions problems that arise among numerous visitors to Basselard stores.
The first question about sharpening that requires a clear answer is the question “why?” It may sound approximately like this:
- Why do I need these? sharp knives, am I going to cut myself with them?
To begin with, we note that a good sharp knife in the kitchen or in nature, and in general in everyday life, is the thing that increases the “quality of life” of a person. A familiar term, isn't it? Opening a package with a knife is much easier than tearing it with your teeth, and cutting sausage and bread is much easier with a sharp knife than a dull one. Moreover, it is much easier to cut yourself with a dull knife, because... when working with it you have to put in more effort and the likelihood that it will slip or twist out of your hand is much higher. Roughly speaking, you need to put pressure on the “dumb piece of hardware” and it needs to be controlled. A sharp knife, oddly enough, on the contrary, protects against injury, since it makes it possible to make easier and more precise movements and spend less energy and get less tired. But this is exactly what a busy person needs to modern man, for whom everything falls out of hand in the evening from fatigue.
Conclusion one: sharp knives will do everything for you, and you just have to get used to them!
- Why do I need a good sharpener if I don’t have normal knives?
In fact, the choice of quality sharpening device has nothing to do with what knives you already have. If you have a knife, it must be sharp! A good sharpener makes any knife sharp, just as a bad one can ruin both an expensive knife and a cheap one. An imperfect sharpening method dooms you to use knives that constantly become dull, and a bad sharpener will not give you the opportunity to sharpen them satisfactorily. In turn, both a cheap and an expensive knife will be happy to be sharpened with a good device. A good sharpener will allow you to get the most out of even a bad knife!
This is the main argument for buying a good sharpening device in any case.
Let me illustrate what was said above. simple example from my own practice.
I apologize in advance for the quality of the photos, since the “life example” was captured impromptu.
One evening I had to cut balyk for dinner. Since this is almost half-raw meat, cutting it thinly and evenly is a difficult task. The best knife in my, oddly enough, rather proletarian kitchen arsenal, was a new Italian knife from the famous company Due Cigni (yellow handle in the photo). Excellent high descents and fine cutting of the knife, with good quality steel, promised excellent cutting in in this case and of course I chose him. The factory sharpening on it was still pretty good, even though it had been in use for quite some time. After cutting the balyk a little, I realized that despite everything described, this knife did not cut thinly and constantly crushed the product. This fact, I must admit, puzzled me. I decided to record what happened next in a photo.
In general, I immediately realized that this was probably due to the peculiarities of sharpening. I note that factory sharpening on most knives is usually done in an aggressive, but rather rough manner. Moreover, the manufacturer is forced to sharpen new knives at a rather large angle in order to protect the cutting edge from possible illiterate handling.
To replace the factory-sharpened knife, I took a simple Chinese-made knife made of unknown steel, which I had once bought in a supermarket (green handle in the photo). With this knife I trained my initial skills in using Japanese “water” sharpening stones, which are now becoming increasingly popular among us. Their distinctive feature is uniformity and non-aggressive sharpening, which allows you to sharpen knives at a slight angle and obtain an even, smooth cutting edge.
This knife did an excellent job cutting meat, slicing quite easily and thinly. The advantage of sharpening on a water stone turned out to be obvious.
Further, experimenting, I decided to take a tourist knife (black handle in the photo), not intended for kitchen use, cut thicker than both previous ones, but also sharpened on water stones. Imagine my surprise when the tourist knife coped with thin slicing of meat not much worse than the well-sharpened “Chinese” mentioned above.
Now I invite the reader to look at the cutting edges of the used knives.
It is obvious that the new Italian Due Cigni was sharpened using the same rather coarse abrasive that was used to polish its escapements.
The cutting edge of the Chinese knife is brought together in the shape of a small lens and not very carefully, since I cannot yet boast of excellent sharpening skills. But at the same time, it is still thinner and smoother than that of the Italian.
The cutting edge of a tourist knife ( last photo) was bred and sharpened on water stones by a master and has a fairly large angle, which is necessary specifically for its intended use.
Among these rather different knives, those that did not skimp on sharpening managed the difficult task of thinly slicing meat. Of course, the “Chinese” is not able to maintain its edge for a long time, like its Italian competitor. But with poor sharpening, all the advantages of a good knife were lost.
It is quite obvious that a well-sharpened inexpensive knife is much better than a cheap and dull one! In turn, buying good knives is pointless without ensuring high-quality sharpening.
In conclusion, of course, I would like to invite dear readers to the Basselard stores, where you can choose knives and sharpeners for any budget and in any combination. For those who decide to take a deeper dive into sharpening issues, I recommend reading Sergei Mitin’s wonderful book, which you can also find here.

Processing of meat, fish and vegetables requires appropriate quality equipment, thanks to which you can prepare food for cooking in a minimally short time. That’s why a professional knife sharpener is so valuable, which will help you perfectly and quickly sharpen the working surfaces of home and restaurant kitchen tools.
The best electric sharpeners at competitive prices
A variety of brands compete to be the best: electric sharpeners for conventional and Edge Ware, Kitchen IQ, Smith`s, etc. - recognized champions in the production of professional kitchen accessories, and not only ordinary utensils, but also universal sharpeners for knives and scissors will be ideal for use. And if someone doesn’t know what scissors are useful for in the kitchen, then we will suggest several options: for cutting off the fins and tails of fish, as well as the stems of any greenery.
With a little internet marketing, you can figure out how to choose the right sharpener for the knives you use every day. Moreover, the modern assortment offers a lot various types tools with the widest range of capabilities, including step-by-step sharpening of knives.
How to sharpen metal surfaces of kitchen appliances
Sharpening serves one purpose - to give the blade sharpness. But few people know that the main point is compliance correct angle cutting edge metal device. Especially if you need to do this operation multiple times. It is this sharpening of cutting surfaces that will help achieve an ideal result in several ways.
One involves using a variety of electric sharpeners; the second - mechanical cutting devices, such as grinding wheels and stones; and the third - this is professional, but using the method of straightening with musat.
Despite the apparent ease of work, not everyone can properly sharpen sharp devices in the kitchen. And all because at a professional level you need to master the basics of each method.
What do we know about sharpening tools?
What do we know about special sharpeners? And not only about the devices themselves - it is important to choose the source material from which the work surfaces are made. For example, for knives it must be not only abrasive, but also highly durable so that it can withstand not just one, but repeated use. This article will be of interest to those who want to learn how to sharpen a tool correctly.
Electric knife sharpening
It may seem that the easiest ones for home and restaurant use are electric sharpening machines. But not everyone understands how to carry out an operation using an electric sharpener safely and in accordance with all the rules. Electric sharpener- This is a special device that operates exclusively from the mains. It is preferred by professionals who, due to the nature of their work, are forced to sharpen kitchen “blades” often and in large quantities. But even ordinary housewives will find this device an excellent assistant for every day. The main thing is to choose a convenient place closer to the power supply and pre-configure everything you need. A professional knife sharpener is a lightweight and small-sized tool, which makes it easy to use in the kitchen. But the blades of the knives become unusually sharp!
They have several holes with which you can set a certain angle of the blade of a single-sided or double-sided knife and, accordingly, the level of sharpening. Such tools are considered the most convenient and modern processing methods. kitchen knives, which can be used independently. Fast and high-quality preparation of tools helps save the cook’s time and effort.
Mechanical sharpening of cutting surfaces
It is popular not only electrical appliance, but also professional sharpener for knives manual. It is a regular sharpening stone built into a miniature machine. These, for example, include the Apex edge pro ultra knife sharpener.
Manual sharpening allows you to change the processing angle, and the working part can be in the form of sharpening stones or steel plates. Sharpening the cutting surface of a blade is a fairly delicate job, and a whetstone is the easiest and most a good option quality care for knives right in your kitchen. It won't take much time and won't require serious skills. With the help of an inexpensive and convenient device, you will ensure that your knives are always sharp, making your cooking work easier. It's just important to remember and use a few simple rules, then processing meat, fish or vegetables will become a real pleasure for both a professional cook and an ordinary housewife.
Several features of mechanical sharpening
- Professional training involves the use of 3 types of sharpening stones with different degrees of grit.
- It is necessary to start sharpening from a block with a larger grain size. It is important that each subsequent sharpening stone eliminates the roughness and scratches that formed on the blade from the work of the previous whetstone.
- Before you start sharpening the blade, it is recommended to wet the surface of the whetstone with water.
The best are Japanese sharpeners, which allow you to process the edge of the blade literally to the point of a razor, which is so important for professional chefs. By the way, ceramic knives can also be sharpened well using Japanese stones.
Types of knife sharpeners
The knife sharpener is a cheap, convenient and simple sharpening machine for home. There are several types of devices with different operating principles and unique shapes:
- a sharpener, the sharpening on which is one-sided;
- a machine that performs classic sharpening of the blade on both sides;
- a mechanical device, the level of knife sharpening on which depends on the applied physical strength of the cook’s hands;
- electric sharpener powered by a drive.
A regular knife sharpening stone is different from a lathe because the latter devices are more efficient and easy to use. Moreover, effective and convenient devices allow you to save energy and time. If working in the kitchen requires you to constantly have sharp knives on hand, then a professional knife sharpener is best solution, especially if it is made by a well-known manufacturer.
Half-sharpening with musat
If daily minor sharpening of the surface of the knife or straightening of an edge curved when cutting hard products is required, then you can use a special device - musat. It is a durable metal rod with a comfortable handle and looks like a round file. Parallel longitudinal ribs are applied to the rod, which create work surface. Very often sharpening musat is sold in a set of knives.
To “straighten” a kitchen tool, just take the grinder perpendicular to the knife and apply it to the edge at an angle of about 25 degrees. With sharp movements along the knife blade, apply the musat on both sides, applying a slight force, which will be quite enough to obtain an ideal surface.
Thus, any of the described devices for sharpening kitchen knives: mechanical, electric, whetstone or sharpening stone will help to constantly maintain steel and ceramic knives in working condition, and the sharpening process itself will bring pleasure to every housewife.
A really interesting knife if you don’t have sharpened hands or are just too lazy to sharpen them by hand, but want to have a sharp knife.
If we immediately start with the shortcomings of the sharpener, then there is essentially one! It has a fixed sharpening angle :)
Well, if anyone is interested in reading about the advantages and taking a closer look, let’s move on...
Not 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, here anyone can do it (even a child and a blonde housewife - I don’t mean hair color)
You need to understand that not just any knife can be sharpened with such a sharpener.
Basic shapes of kitchen knife blades
1 - wedge-shaped slopes from the butt itself, traditional cutting edge. One of the most common shapes for kitchen knives. Cuts thick layers of material very easily;
2 - wedge-shaped slopes starting from the butt, which directly form the cutting edge. This is a fairly common form, but during the sharpening process it almost always turns into type 1. Due to the large area of the slopes at the point, the block is “oiled” with foreign metal, so sharpening such a knife correctly is much more difficult than option 3. Of course, after the point of the knife, polishing of the side surfaces is required, if it appearance important for the owner;
3 - flat blade, wedge-shaped slopes form a cutting edge, starting from the middle or two-thirds of the width of the blade (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 bevel planes set the sharpening angle, while having a relatively small area;
4 - flat blade, wedge-shaped bevels, traditional cutting edge. The most common profile option. Allows you to vary the sharpening angle. The knife is quite durable and cuts relatively easily;
5 - flat blade, wedge-shaped slopes, the cutting edge is formed by a double wedge. If in option 4 the cutting edge wedge is single, then in option 5 some of the material is removed from the corners between the bevel and the edge. As a result, the knife experiences less resistance when cutting thick and dense materials. It is almost never found in factory products, but can be recommended as a basic one to people who have mastered the manual sharpening knives;
6 - flat blade, lens-shaped concave slopes. The angle of the cutting edge is formed by the continuation of two planes drawn from the edge between the blade and the slope to the tip. This sharpening is also called “razor sharpening” - it is typical for straight razors. Easy to sharpen and straighten - the edge 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 very well comparatively thin materials, 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 badly damaged. Minus - the knife is designed for one hand only, the bevel should be on the side working hand. In this case, a right-handed blade is shown (assuming we are looking at the blade from the handle side);
8 - is actually option 3, only the angle of the cutting edge is such that there are no descents as such. The shape of the blade is typical for cheap Chinese counterfeits of branded knives, as well as for all kinds of chopping tools;
9 - “ogival” or “bullet” sharpening. Feature- convex lens-shaped slopes. It doesn't cut very well, it gets stuck in the material, but it cuts perfectly. Of course, such knives are more difficult and expensive to manufacture and sharpen than option 8.
The cutting edges are highlighted in red.
Most high-quality kitchen knives have blades that start almost from the butt and a small, thin cutting edge. Accordingly, the sharpening process consists precisely in the formation of the correct cutting edge. Its ideal form is a wedge (option 3), or a two-stage (double) wedge (option 5).
The sharpener is a slightly modified, very popular Nakatomi NEC-2000 sharpener. They have interchangeable replaceable diamond rollers, the same power and everything else :) 
Description:
The electric sharpener is suitable for all types of knives, including ceramic ones; With its help you can sharpen knives with both single-sided and double-sided sharpening. The sharpener is dual-functional, providing not only sharpening, but also finishing. Equipped with a replaceable diamond roller, it is easy to use and does not require any knife sharpening skills.Suitable for steel and ceramic knives.
Suitable for knives with single-sided and double-sided sharpening.
Sharpening and finishing functionality.
Replaceable diamond rollers.
Mains powered.Home electric sharpener with diamond-coated sharpening discs for sharpening and straightening kitchen knives.
The sharpener operates at 220 volts, motor power 18W
Dimensions: Length - 14.5 cm (with removable block 22 cm), width 7.5 cm, height 8 cm
Grit - sharpening 600 grit, grinding 1000 grit
The review will use photographs from the “double” of this sharpener, Samura SEC-2000, sold in online stores in Russia. There is actually no difference (except for a minor one in design), it is quite likely that they came off the same assembly line.
And, well, yes, the one sold in Russia is still three times more expensive :) The block with diamond discs on all these blades is used alone and is interchangeable, so the sharpening quality is the same
Package (in my case Samura).
Funny logo :) with a hint of involvement in Japan, as well as the brand name itself...
The Samura brand is a relatively recognizable one, specializing in knives and their maintenance.
From one end brief description, with a highlighted warning, read the instructions before use. 
Appearance and dimensions:
Everything inside is extremely ascetic, for such a price you could spend money on a normal instruction manual :( 
Power unit. 
And the knife itself. Everything is just as simple and without surprises. 
Side power switch 
On the opposite side there is a replaceable block for sharpening (can be purchased separately)
There are rubberized feet on the bottom to reduce vibrations and prevent the knife from simply “driving” around the table. 
Side view - sharpening unit removed. The drive mechanism for the diamond discs is visible. 
Rear side - socket for connecting the power supply 
The electric sharpener is quite massive and has a “noticeable” weight 
The dimensions are not very large, it will not take up much space in the kitchen. You can also put it in a locker. 
Structure of the diamond disc block:
The rod with the discs is mounted on two bearings and the discs themselves are spring-loaded. When “dragging” the knife, they move slightly. 
There are four holes for sharpening. Each under one side of the knife. Two for rough sharpening and creating an angle with 600 grit and two for sanding and lining with 1000 grit 
It seems like they write that the sharpener is designed for sharpening knives with a spine thickness of no more than 3 mm, but perhaps this is not entirely true.
You can remove the plastic plugs from the block of diamond discs, and you will even have excellent access for sharpening the axe. Of course, one must keep in mind the precautions for such sharpening.
To sharpen a knife, just connect the power supply to the sharpener, plug it into the network and turn on the sharpener.
There are four holes in the disk block, the first two are for rough sharpening “1”, the other two are for finishing. Each of the holes is for one side of the knife. Sharpen one side of the knife first, then the other.
There is no need to press hard, just pull it towards you. After a small, uniform edge appears on the blade (you can feel it with your finger), we repeat the procedure on 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 another knife. If the knives are in adequate condition, then sharpening with a fine abrasive is sufficient; coarse sharpening is not required for them.
There is no need to maintain angles for sharpening. The whole procedure takes about half a minute or a minute. It sharpens knives very well (really), and even our “nameless” knives are not inferior to brands after sharpening (at least for a while;)
You can sharpen not only metal, but also ceramics! The sharpener makes noise during operation, but not very much.
The sharpener needs to be cleaned from time to time:
-rotate the sharpening block clockwise until it clicks.
-remove it from the common block.
-remove the cover of the guide knives and shake it out.
A small study on the quality of sharpening with household sharpeners
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 - at the beginning of the experiment it is pretty “tormented”. 
I immediately apologize for the “dirty” scissors, they’ve been lying around for a long time - I didn’t pay attention when photographing them, but the enlarged photos look terrible :)
I’ll put a mark on the blade of the knife with a marker - we’ll look at a specific place. As you can see in the first photo, the knife is not only dull - it has a blade with a notch/damage. 
The first knife, 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 metal along the surface. In fact, after sharpening with this knife, it seemed to me that the blade became even duller :)
The blade was like this 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 damages the blade. 
This is partly visible on the edge - the damage that was originally on the blade has gone away. It can only be called a knife with a big stretch. The stone has probably worn out, and now the knife removes metal not only from the side surface, but also from the edge ( however, it’s good that she hasn’t sharpened before).
The next one, similar in appearance, is a knife from Ikea. She, 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, sharpening not along the surface, but at an angle. 
The photo shows the result of her work.
The edge has been sharpened after the work of the previous knife. 
And a more correct sharpening is visible on the side surface 
And finally Samura...
After preliminary sharpening to 600 grit (holes “1”) 
And after finishing at “2” 
Almost “strictly according to science” ;) 
An electric sharpener is certainly not cheap, but the savings in time and effort are colossal. And most importantly, the result is excellent!
After writing this review, I chopped some shreds for lunch, the old knife (after a 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 is that its name on the seller’s page (or rather its interpretation) confuses me - I didn’t dare to post a review with that title, “because they’ll ban you” ;) Read the beginning of the name, you’ll understand for yourself :))) )
“Good luck everywhere” to everyone, stop by for a review;)
I'm planning to buy +106 Add to favorites I liked the review +65 +135In home life there is no particular need for a sharpening machine. It’s easier and faster to sharpen knives with knife sharpeners, and the sharpening machine actually won’t have any other work to do. Another thing is when there is a need for sharpening cutting tool. Axes, chisels, chisels, drills, cutters, planer knives and other tools are sometimes simply impossible to sharpen by hand. Then it will come to the rescue sharpening machine.
The structure of the sharpening machine is simple to the point of primitiveness: one or, most often, two abrasive discs are located directly on the motor shaft. As a rule, one disk has a coarse grain and is intended for coarse sharpening, the second disk has a fine grain - for subsequent finishing or grinding. But different instrument requires various conditions processing, so sharpening machines still have a division into certain classes.
The most common type of sharpener is high-speed (from 2000 to 10,000 rpm) machines with two disks located on the shaft of one electric motor on different sides. This type of sharpener is usually used for sharpening metal tool with a thick cutting edge - drills, chisels, axes. When sharpening knives and chisels on such a sharpener, you should be careful - thin metal can quickly overheat. If scale appears on the cutting edge, the hardened steel “sinks” - it becomes soft, cuts poorly, and quickly wears out. Therefore, overheating should not be allowed. This leads to some inconvenience when sharpening knives on such a machine. Some models of sharpeners equipped with a speed controller do not have this drawback, but more often angle sharpening machines are used to sharpen thin blades.
In angle grinders, only one abrasive disc is located directly on the motor shaft. The second – grinding – disc is connected to the engine through a gearbox, which reduces the rotation speed to 120-150 rpm. In addition, this disc is usually located in a bath into which water can be poured, ensuring constant water cooling of the surface being sharpened. Such machines are more universal, but, for example, for drill sharpening will not fit well: the only high-speed disc has a coarse grain, and hard tool steel can be sharpened at a slow speed grinding wheel It won't be easy.
Another type of sharpening machines is sharpening and grinding. Instead of a second abrasive wheel, they have a sanding belt installed. This solution significantly expands the functionality of the machine, allowing not only to sharpen and grind cutting tools, but also to use it, for example, for grinding small parts that are inconvenient to handle with grinders.
Some manufacturers have gone even further by providing the ability to connect a flexible shaft with an engraving machine to the engine. Such a tool is highly powerful - engraving machines of comparable power will cost much more.
Some sharpening machines are equipped with accessories for sharpening drills, saw chains, circular saws, and other tools, and for sharpeners with a narrow specialization, special sharpening machines are offered: for drills, for chains, etc.
Characteristics of sharpening machines.
Power. The more power a sharpening machine has, the greater the load that can be placed on the grinding wheel without the risk of overheating the engine. The larger the tools and parts that are supposed to be sharpened, the more power is required. To sharpen thin and small tools (knives for engravings or wood carvings, thin drills and chisels), high power is not needed. For everyday use, a power of 150-250W will be sufficient, but for sharpening axes, shovels and scythes, it is better to choose a machine with more power.
Maximum speed. The optimal rotation speed of grinding machines was selected a long time ago: it is 2700-3000 rpm. A lower speed leads to a decrease in productivity; at a higher speed, the material of the sharpened products will begin to overheat. High speeds are only necessary when sharpening carbide tools with fine abrasive (diamond) discs. The grain of such a disk is so fine that at normal speed its performance will be too low. Therefore, cutting elements made of hard alloys (puncher drill heads, drill heads, soldering on circular saws) are sharpened with diamond discs at frequencies up to 15,000 rpm.
Wheel diameter. Small wheels with a small bore diameter are usually used in low-power household models. You cannot place a large and heavy abrasive wheel on a small diameter shaft - the slightest imbalance in it will quickly lead to bending of the shaft and beating of the disc, which will have a bad effect on the quality of sharpening. Powerful models usually have a larger diameter shaft and, accordingly, a larger diameter seat. But even on a low-power model, a large bore diameter will not be a disadvantage - it will ensure the absence of runout, which is very important for high-quality sharpening of thin tools.
Circle diameter. The larger the tool you plan to sharpen, the larger the diameter of the circle the machine should have: a small circle when sharpening scythes and axes will quickly wear off and require replacement. In addition, the large abrasive wheel has high inertia - this ensures smoother grinding and an even load on the engine, which has a beneficial effect on its service life. At the same time, the diameter of the circle is directly related to the power of the machine and, accordingly, to its price. Therefore, to sharpen small tools, use wheels large diameter inappropriate.
Circle thickness. Just like the diameter, it depends on the size of the tool being processed. When sharpening chisels and other cutting tools of small width, it is advisable to choose a wheel with a thickness slightly greater than the width of the tool being sharpened. Another argument in favor of thicker wheels is that a thin wheel wears down faster or loses its shape, causing it to become unbalanced. In both cases, the circle will need to be replaced. But the greater thickness of the circle increases its mass, and, accordingly, requires more engine power.
Besides these general characteristics, you should also pay attention to the equipment of the machine and the presence of additional options in it:
Protective cover And transparent protective screen– the necessary minimum to ensure the safety of any sharpening machine. Abrasive wheels are made of brittle material, and a damaged grinding wheel can instantly break into several pieces. Failure to use the protective cover and shield in this situation can result in serious injury.
Backlight in the form of a lamp on a flexible leg or individual for each disc - a very useful option when you need to carefully monitor the contact area between the tool being sharpened and the disc.
Work site with a variable angle of inclination can be very useful when sharpening tools with a clearly defined sharpening angle: drills, chisels, chisels.
Possibility of attachment to a supporting surface is absolutely necessary when sharpening large tools: even the most powerful sharpening machines have a small mass and it can easily be accidentally moved out of place and even dropped. During operation, this can lead to damage to both the tool being sharpened and the machine itself. Therefore, if there is such a possibility, it is better to screw the machine “tightly” to the workbench. Even when sharpening small tools, this will increase the convenience of work.
Choices.
If you need a sharpening machine quite rarely and the requirements for the quality of sharpening are low, choose from cheap ones basic models in the range from 1700 to 3000 rubles. As a rule, they are unable to operate continuously for more than a few minutes, but they will not put a strain on your budget. A sharpening machine is a very simple tool, so even the cheapest models from little-known manufacturers are quite reliable and, with proper care, can last for many years.
If you need a universal sharpening machine not only for most types of tools, but also for kitchen knives, pay attention to angle machines with a gearbox and a reservoir for “wet” sharpening. The high-speed first disc is suitable for coarse sharpening of cutting tools. And the low rotation speed of the second disk and water cooling of its surface guarantee high-quality sharpening of knives without the risk of damage. Just remember to drain the water after sharpening - otherwise the disc will absorb it from the submerged side and become unbalanced. Such a machine will cost you 3000-5000 rubles.
If you need a machine for frequent and high-quality sharpening of a variety of tools, including drills and cutters, pay attention to compact high-power machines - this guarantees long-term operation of the tool without the risk of engine overheating. Such machines are presented in the range from 2500 to 5000 rubles.
If you need not only a sharpening machine, but also a powerful engraving machine, pay attention to the two-in-one kits. And the speed control present in such machines will be a pleasant addition and will allow you to sharpen thin blades that are afraid of overheating at low speed. These machines cost from 3,000 to 4,000 rubles.
If you often have to sharpen drills or saw chains, you may want to consider purchasing specialized sharpeners. Sharpeners for drills are available at prices starting from 1800 rubles, for saw chains – from 2800 rubles.
Finally, if you need a machine to sharpen large tools and garden tools, look for heavy-duty machines with large abrasive wheels. They will cost in the range from 5,000 to 11,000 rubles.
