Chef’sChoice Trizor XV EdgeSelect
This sharpener from Chef’s Choice is the ultimate changer in sharpening. However, before we introduce you to its incredible features, we must first introduce you to some bevels.
Different knives have blades of different shapes and angles. The angle and shape determine the ease of cutting a certain material and the life of the blade.
Most Western knives have a thicker angle, while Asian knives (such as Santoku knives) have a thinner angle of 15 degrees.
Nowadays, everyone wants to use this 15-degree bevel for general cooking purposes, because it can provide higher precision, less cutting friction, and is very sharp.
The function of Chef’s Choice, a powerful machine, is that it allows you to convert any knife angle into a very ideal 15-degree angle.
This means that you don’t have to go to Japan alone, or if you have this kind of sharpener at home, you don’t have to spend a lot of money on expensive 15-degree angle knives.
However, the traditional 15-degree oblique angle has a drop point, and that is the fact that they tend to chip or crack due to their thinness.
The good news is that this machine has taken this into consideration and converts your tool to a 15-degree angle with a triple bevel so that its durability will not be compromised.
This means that using this sharpener will hit two birds with a stone. You will get an acute angle of 15 degrees and high durability.
Although the whole process sounds very technical, because this machine makes it easy for you to complete this extraordinary task, you don’t have to be threatened.
It has a three-stage process and three different types of slots suitable for its specific purpose.
The grinding discs in the slots of the first and second stages are made of pure diamond abrasives, which are used to sharpen the blade to form a bevel on the knife to improve durability and form a 15-degree angle on the blade.
Then, a layer of combustible material is plated on the third-level slot, which will lightly sand and flatten the sharpened knife so that the blade has a smooth finish.
All three types of slots are equipped with flexible angle guides, which means you don’t have to rely on guesswork to determine the sharpening angle.
This machine can be used to sharpen any type of kitchen knives, sports knives, pocket knives, and even serrated knives.
Pros
- It not only allows you to turn a 20-degree bevel knife into a 15-degree bevel knife, but it is also a converter.

- The machine is easy to operate but can achieve excellent sharpening results
- It has a grinding disc made of 100% diamond abrasive and flexible wire drawing material

As the name suggests, the term “Hybrid” means that this sharpener is semi-electric. After the knife is grounded in the first step, a manual honing step is required.
Compared with the honing step, the honing step is a finer and more detailed step. Therefore, Chef’s Choice takes the initiative to set the honing step to be manual instead of electric.
This means that you can decide how many times you should run the blade in each slot based on your own judgment, and you can better control how to polish the blade.
In addition to the above functions, the grinding wheel of the machine is made of 100% diamond abrasive, and it is also made of a cross shape to make your knife have better “occlusivity”.
The white body of the machine makes its appearance classic and adds a sense of decoration to the kitchen.

In addition to this, it also has all the excellent features you can find on the 15 Trizor XV model, such as 100% diamond abrasives for the first and second stages, bendable angle guides, and bevels for the third stage plate.

They are all made of diamond abrasives, and when combined with the powerful motor of the machine, they can hold the chips on the blade even 1 mm deep.

Sharpening a knife with an electric sharpener requires knowledge of some technical concepts, so we will break down these concepts in the next part so that you can have an in-depth understanding of the electric sharpener before you go out and buy it yourself.
What is a Sharpening angle?
When you look at the descriptions of many sharpeners, you will often come across this term. But what does this mean? Well, in simple terms, this means that your knife has a specific angle for making the blade’s edge.
This angle determines the sharpness and durability of the knife. Since this angle may be different from one knife to another, it is important to sharpen the knife at an angle suitable for the angle of the blade.
This can be done in many different ways.
If you are not sure about the angle, you can use a sharpener with an angle guide, which will “guide” your knife when sharpening. This makes the whole process very easy because you don’t have to guess the angle of the knife.
Another excellent angle guide is the flexible angle guide. After fixing the angle guide, you must be very careful when sharpening the knife so as not to apply too much pressure and not to move the knife awkwardly.
However, when the guide is flexible, it will guide your knife with higher efficiency and accuracy.
If you are more experienced in using and maintaining various tools and want to control the sharpening angle, you can choose a sharpener with a dial, which can be used to set the angle to the most suitable angle. The knife you are cutting.
You may have heard that the thinner the angle, the sharper the blade.
Although this is part of the truth, the whole picture is not as simple as this, so if you want to know more about the sharpening angle and how to sharpen it, It does affect the performance and durability of the knife.
It is best to have a deep understanding of the knife before getting a simple conclusion.
Sharpening, grinding, and honing – are they the same?
Most electric sharpeners have a two-stage or three-stage process, and a different slot is designated for each stage. You may ask why, and this part will give you the answer.
Although we may refer to the blunt edge of a fixed blade as “sharpening” for short, “sharpening” has some basic parts.
First, use a rough abrasive material to remove the passivation and damaged parts of the blade, which is called grinding.
This is the first step in the sharpening process. Then there is honing, which is smoothing the blades.
When the blade is ground in the first step, the material is removed from the blade and a “wire edge” is formed, which is neither smooth nor durable.
The second step, honing, removes fine spots, and makes the edges more durable. Therefore, compared with rougher grinding stones, the stone used in this step has fine gravel.
This is why high-quality sharpeners should have separate grinding and honing grooves to achieve professional-level grinding results.
How often should I sharpen the knife?
This is one of the frequently asked questions but no definite answer. Figuring out how long it takes to sharpen a knife is tricky because there are multiple factors that affect how often you should sharpen a particular knife.
First, it depends on the number of knives you use. If you use a knife frequently, it is best to sharpen the knife once a week.
But the other part of grinding (ie grinding) does not need to be done so frequently, and sharpening the knife too frequently will actually remove too much material from the blade and cause damage.
Generally, a knife needs to be sharpened once or twice a year, but depending on your usage, polishing and honing can be done more frequently.
Another factor that determines how long a knife needs to be sharpened is the purpose for which you use the knife.
For example, a knife used to cut hard materials such as bones will require more maintenance than a knife used to cut softer materials.
Although it is difficult to guess whether your knife needs to be honed or sharpened, there are some simple ways to help you know that your knife is not sharp enough.
One of the easiest ways to judge is when your knife squeezes something soft such as a tomato, instead of cutting it steadily; another way to judge is to feel the blade carefully with your thumb to see if there are burrs on the blade.
edge. Although most of the technical aspects of the electric knife sharpener have been broken down for your easy understanding, the most important question still remains, that is, how to choose the correct electric knife sharpener.
But rest assured, the next section will answer you because here we will discuss some key factors to help you determine which sharpener is best for you.
Things to consider before buying an electric sharpener
Type of sharpening wheel
It is very important to understand the material and mechanism of the sharpener used to sharpen the knife. A common sharpening material used in sharpeners is diamond.
When you hear 100% diamond abrasive, you might think it is great because it is one of the hardest materials and should be strong enough to effectively grind damaged blades.
Although this is part of the fact, it is also true that diamond abrasives can be highly corrosive and can damage precision knives instead of sharpening them.
If you usually want to sharpen the knife, diamond abrasives are a good choice, but if you want to sharpen a thin and fragile knife, make sure you don’t over sharpen the blade.
Another good choice for diamond abrasives is abrasive belts, which are flexible enough to adapt to different types of blade materials and different shapes of blades.
Therefore, if you have a unique tool with unique material and curve, you can choose to use a flexible abrasive belt instead of a sharpener with a fixed stone.
Number of stages in the sharpening process
Most knife sharpeners have two or three sets of slots, which are assigned to different stages of the process.
The number of stages will affect the complexity of the machine operation, the size of the machine, and the accuracy of the sharpening.
If you need rough grinding, precision grinding, and polishing, you can buy a sharpener through a three-stage process.
If you are looking for a compact and simple sharpener, you can choose a sharpener with a two-stage process.
Angle guides
As we discussed in the previous section of this article, knife sharpening involves a thing called sharpening an angle.
If you are an expert proficient in knives, that is great, you can find out at which angle to sharpen the knives, but this is not the case for most cutter users.
Therefore, it is essential that the sharpener must have a way to direct your blade to the correct angle for sharpening.
Conclusion
Using an electric knife sharpener at home is an easy way to properly maintain your knives, and we hope this article has eliminated your confusion about how to buy knives.
Now that you know what the best electric sharpener is on the market, you can rest assured to buy a wise sharpener and then buy it.
With an electric knife sharpener, you will be able to experience a sharp cutting experience, which will definitely increase the joy of cooking.
