Wüsthof PEtec

Maximum Sharpness

Knife sharpeners have come a long way since the old days, where sharpening a knife was done mostly with a sharpening stone of some kind. Nowadays, electric knife sharpeners are able to give you even better sharpness while maintaining the integrity of the knife, and make the whole process much easier in the process. The march of technology has allowed electric knife sharpeners to achieve the type of precision that simply wasn't possible before, while making the process as simple as possible. Where knife sharpening could take quite a bit of time when done manually, an electric knife sharpener has the ability to make it no more than a few seconds.

The Wüsthof PEtec Electric Sharpener is a great example of an electric knife sharpener that has increased the precision of the process while simplifying it greatly. Thanks to the unique PETech technology and special lasers that are built into it, the device determines the angle of sharpening of the blade before editing, and also controls the angle during sharpening - this allows you to achieve sharpness along the entire length of the blade without worry of the blade not being sharpened at the proper angle. Furthermore, the process of sharpening requires little more than pulling the knife through the slots a few times, making it as simple for the user as possible.

Perfect for Japanese Knives

If you are a fan of Japanese knives and use them for cooking, then you definitely need this model: it rules the blades at an angle of 14º - Asian-style blades like Santoku, Nakirls, Chai Daos etc. require such sharpening. However, users have reported success with plenty of other types of knives as well, even including hunting knives, so this device should work fine with most knives that are made to be sharpened at the specific angle specified.

This device uses a three stage sharpening process for the sharpening of each knife. The first stage requires running the knife through 3 or 4 times, with the second stage requiring only 1 or 2 times, and the third stage another 3 or 4 times. In all, running the knife through the 3 stage sharpening process should take no more than a couple of minutes at the most. The end result will be a knife that is razor sharp, able to cut extremely thin slices of any kind of ingredients. Just be sure to be extra careful with a freshly sharpened knife, as many people often experience cuts or worse injuries when not handled correctly.

Overall, this three-stage knife sharpening kit from Wusthof will be a welcome addition in any kitchen where knives are very often used.

Presto 08810 Professional

Durable Knife Sharpener

Knife sharpeners are quite handy to have whenever you need to make sure that the knives in your kitchen are always sharp. However, just as with any kind of motorized device, or any device with moving parts, there is always the risk of them breaking down. Furthermore, with a knife sharpener there is always a risk of the sharpening materials inside of the unit eventually wearing out and becoming ineffective. And when this happens, it is usually at the worst possible time, which leaves you with a relatively expensive appliance that isn't doing anyone any good. Unfortunately, many electric knife sharpener manufacturers don't build their units with reliability in mind.

The Presto 08810 Professional Knife Sharpener is one unit that stands above the rest thanks to its high durability and wear resistance. Sapphirite™ Coarse-grinding and medium-grinding wheels are installed here, which are known for their amazing wear resistance. As a result, even after hundreds of sharpened blades, they will retain their original shape and will not need to be replaced, letting you continue to use the unit to sharpen your knives to perfection without worries of replacing the unit or the grinding wheels.

Review of Presto 08810 Professional Knife Sharpener

Sharpen Any Blade

One of the biggest concerns with any electric knife sharpener is in what kind of blades it is able to sharpen. Many of the models available tend to be very limited with the types of blades they are made to handle. However, this model gives you plenty of flexibility where others don't. As you know, each type of knife requires a certain sharpening, and Presto took this moment into account when creating this knife sharpener. 3 available modes will help you choose the best for thin, medium and thick blades, letting most people easily sharpen their entire arsenal of kitchen knives with the same unit.

As with most of the best knife sharpeners out there, this unit includes 3 sharpening stages to ensure that you knives are not only sharpened to perfection, but also that they remain durable despite the sharpening. The three separate slot spaces are for each stage, with the process only requiring that you pull the knife through each slot a few times to achieve the best sharpening and polishing experience. Some users complain that the unit isn't the most stable, with the anti-slip feet not working very well, but placing the unit on most kitchen countertops should provide enough stability for safe operation. For those who have a whole range of different kinds of knives that need to be sharpened, this electric knife sharpener should have you covered.

Grocery Art 3-in-1

Safe and Stable

A big concern when handling knives of any kind is safety. After all, knives are meant for cutting, with certain knives geared specifically for cutting through flesh and bone, which can certainly pose a problem when handling them if not done so in a safe manner. Anyone who has spent any amount of time cutting ingredients in a kitchen probably has the scars on their fingers to prove this. This same safety concern carries through with any electric knife sharpener, as any device that forces you to hold or wield the knife in an unsafe manner runs the risk of causing injury. That is why the safety aspects of any knife sharpener that you use are at least as important as its effectiveness in sharpening knives, if not more so.

The Grocery Art 3-in-1 Knife Sharpener is an electric knife sharpener that was made with safety of use as a top priority. Suction cups placed on the bottom of the unit guarantee a reliable and sturdy placement of the device on the table, and therefore the likelihood of its displacement and slipping of the knife during sharpening is minimal, something that can be all too common when using a knife sharpener. Furthermore, the slots on the device allow for easily placing the blade of the knife inside for sharpening, further increasing its overall safety.

Review of Grocery Art 3-in-1 Knife Sharpener

3-in-1 Knife Sharpener

The complaint about many electric knife sharpeners not being able to handle many common kitchen knives doesn't apply here. This 3-in-1 unit is able to handle just about any kind of kitchen knife that you throw at it. This unit uses a 2 stage sharpening process to sharpen and polish your knifes to pinpoint precision, making them just as sharp - if not sharper - than the day you purchased them. The sharpening process is quite easy, requiring nothing more than putting your knife into the sharpening slot and pressing the power button, and in a few moments your knife will be ready to go.

One of the best things about this unit is its compact design. Many of the electric knife sharpeners on the market are relatively bulky, and thus take up a lot of space on a kitchen countertop or table. Not so with this device, as its small footprint takes up only a minimal amount of space, letting you easily place it amongst the other items that you normally leave on your countertop.

In the end, this model is an indispensable assistant in every home, because with its help you can sharpen not only knives, but also scissors and even screwdrivers. Buy it, and all the knives in the house will remain sharp for many years.

LINKYO LY-KE2SSA1

Type and Features

The electric knife sharpener LINKYO is an excellent choice for housemakers who hate tricky operation. The body includes two grooves for 2-stage sharpening. The abrasive discs are located in the grooves, and they sharpen your knives while rotating. The suction cup provides the stability of the device. One more advantage is a built-in "stop". How does it actually work? If you apply too much pressure on a knife, the safety system will stop rotation of discs. Moreover, the metal chips are collected inside the sharpener. So, having pulled two plugs out of the sharpener base, you can easily remove them after use.

Review of LINKYO LY-KE2SSA1 Electric Knife Sharpener

Sharpening Angle

The automatic adjustment of the sharpening angle highlights its extra convenience. The most appropriate sharpening angles were provided by the manufacturer, and you just need to follow the manual.

Sharpening Stages

This knife sharpener will allow you to keep all your knives in tip-top condition. Still, you should consider that this knife sharpener is designed solely for metal knives with straight blades. At the first stage of sharpening, the angle of the knife blade is rejuvenated and all damages are eliminated. The second stage involves the blade honing and polishing. You should pull your knife through each groove equally to provide the high-quality sharpening.

What Is an Electric Knife Sharpener?

Everyone who has a kitchen has at least one knife in it, with most kitchens usually having at least a set of knives that are used for cooking. Most well-made kitchen knives tend to be very durable and will last for many years, but even the most durable knife will eventually need to be sharpened. This is especially true of any kitchen where food is prepared on a daily basis. The more wear a knife gets from being used, the duller the blade gets, which eventually leads to the knife being less than effective in cutting various ingredients. This is why every kitchen needs a knife sharpener of some kind.

One of the best types of knife sharpeners to get is an electric knife sharpener, which is an electrically-powered device used for sharpening the blades of knives. Instead of the tedious process of sharpening a knife manually, an electric knife sharpener makes the process much easier by using motors to provide the movement of the internal components. In fact, not only are electric knife sharpeners much easier to use, they often tend to be much better with keeping a knife balanced properly and in tip-top shape, as most contain two or more stages of sharpening to provide a well-balanced knife.

If you need new knives for your kitchen, then take a look at our reviews of the best knife sets.

What Features to Compare

Most people who aren't familiar with electric knife sharpeners are not likely to have any idea of what to look for in a product. This may lead to someone buying one that is not at all suited for their needs, should they do so without being aware of the differences between the various models. The first thing to remember is that not all knife sharpeners are the same. Different models will often be suited for different kinds of knives, so anyone who purchases one should be aware of the various characteristics of the different electric knife sharpeners on the market. Below are these main characteristics to consider. Knowing these will help ensure that you can purchase the best electric knife sharpener for your needs.

Best For

The first thing to be aware of with any knife sharpener is for what kinds of knives it is best for. As any experienced chef can tell you that not all knives are the same, this also applies to knife sharpeners. Different models will be best suited for different kinds of knives, so it is best to make sure that the model you purchase is well suited for the types of knives in your kitchen.

Design

The design of any electric knife sharpener will help show the various characteristics that it has that sets it apart from other models. Such design features as its stability, components for sharpening, and other things will help give you an idea of how easily the unit can be used.

Sharpening Angle

One important characteristic that many novices to knife sharpeners most likely won't be aware of is the sharpening angle of the device. Certain types of knives require sharpening at a very specific angle, and not all knife sharpeners are suited to support all necessary angles. For instance, knife sharpeners that work at a 14-degree angle are mostly suited for tasks that require a very thin blade, especially when cooking any types of Asian dishes, while steak knifes will often have a higher angle to them. Some models may also support varying angles, so if you have knives that require sharpening at different angles, you will want to make sure that the model you purchase supports them.

Sharpening Stages

One last aspect to be aware of with any electric knife sharpener is the number of sharpening stages that it has. The proper sharpening of a kitchen knife is usually a multi-staged process that ensures not only the proper sharpening of the blade, but of helping it maintain its strength and integrity as well. Most electric knife sharpeners will have either 2 or 3 sharpening stages included, with the first stage being the sharpening and beveling, the second stage honing, and the third stage stropping and resharpening.
