Perfect for the Kitchen

Most people who spend a lot of time cooking have a decent collection of knives, but one appliance that is often missing from a kitchen is a good knife sharpener. Even the hardiest knives will need sharpening after years of heavy use, and as such, you need a great tool for providing the perfect sharpness to your precious knife collection. The Wüsthof Easy Edge Electric Sharpener will fit this bill perfectly, whether you are a casual cook who mainly just cooks to feed your family, or a professional caterer or chef who cooks for a living.

Made in a heavy-duty case, this knife sharpener is attractive enough to remain out in anyone's kitchen while also leaving a small enough footprint to where it won't easily get in your way. Having said that, it is also easy enough to handle to where you can just bring it out when you need it and keep it in storage the rest of the time. Just bear in mind, though, that when this knife sharpener is cleaned, the internals and external case both need to be completely dry before putting it into storage. This is worth noting as it can take a while to dry, so just keep that in mind.

Easy Sharpening

The overall design of a knife sharpener is really only a secondary concern, however. What really matters to most people is how well the sharpener works at doing its job, and here you get one of the best units out there. The knife sharpening happens in three easy steps. First, the sharpening occurs with the bezel performing a 14 degree sharpening on any knife, making it extremely sharp. Next, the honing is performed, allowing you to create an arch-shaped edge that will give the perfect balance of sharpness and durability to the edge of the blade. Finally, the polishing, stropping, and resharpening are all performed, letting you whet your blades to perfection. You'll notice an immediate difference with any knife sharpened by this unit once you start using it.

Controlling the device is actually pretty simple, with clear instructions that allow anyone to try their hand at sharpening any blade. What is really great about this unit, though, is that this works perfectly for sharpening expensive knives, letting you get the perfect sharpness and polishing without any risk of damaging the blades. Overall, we are certain that both regular kitchen users as well as professionals will be glad to have this knife sharpener as a permanent part of their kitchen.

No blade damage there with the higher-quality steel -- just a wicked-sharp knife.

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.

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.

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.

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.

Simple and Effective

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 excellent stability to the device, so you won't need to constantly hold it down with one hand, or worry about it sliding around while sharpening. 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.

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. It is enough to pull your knife through the sharpener several times without pressing too much and make your knife truly sharp. Amazing! The LINKYO Electric Knife Sharpener really is an ideal option for those who wish to make sharpening easy.

Maintain Your Knives

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 damage is eliminated, even if there are deep gorges in the edge of the blade. The second stage involves the blade honing and polishing. You should pull your knife through each groove equally to provide the highest quality sharpening. Since this is only a two stage sharpener, you'll find that you should be able to work through a whole collection of blades pretty quickly, so you won't need to waste a lot of time sharpening.

Once all of your blades are sharpened, you should notice a considerable improvement in the cutting performance of any blade sharpened by this device. Furthermore, the sharpener is relatively easy to clean and maintain, requiring little in the way of work for either of these things. Finally, you'll find the combination of its small footprint great for putting it just about anywhere, so you can either leave it out or store it away without it getting in the way. At the end of the day, this knife sharpener gives you great sharpening at a very affordable price.

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.
