Best Electric Knife Sharpener Consumer Reports, Ratings, Reviews, Tips, and Guides in 2022

Have you ever tried using an electric knife sharpener? They can be a handy tool for those who love to cook! They tend to get the job done faster than sharpening a knife by hand. There are many electric knife sharpeners on the market, but you probably have no idea which ones are worth buying. That’s why I decided to create this buying guide post, where I explain what essential things to look for when purchasing an electric knife sharpener.

If you are tired of using those old fashioned manual knives and are looking to sharpen your knives the new automatic way, then it’s time to buy an electric knife sharpener.

What is an electric knife sharpener?

An electric knife sharpener is a device that uses an abrasive wheel to sharpen your knives. The abrasive wheel is usually made of diamonds or ceramic, and it spins very quickly. You place the blade of your knife into the device and move it back and forth as you press down on the handle. This action causes the abrasive wheel to grind away at the edge of your knife and sharpen it, making it sharper than ever before.

Electric knife sharpeners are designed to be used at home, but they can also be found in many professional kitchens across America. They allow chefs to ensure that their knives are always sharpened properly so that they can perform their best when preparing food for clients or customers.

How does electric knife sharpener work?

The electric knife sharpener works by grinding away the dull areas of a knife. The machine has a base that has been designed to fit securely over the blade, and a handle that helps you hold your knife while you sharpen it.

The machine comes with two sharpening stages: one for coarse edges, and one for fine edges. The first stage removes dull edges; the second stage sharpens those edges that remain. There are also settings on the machine to control how fast or slow it grinds down your blade.

When using an electric knife sharpener, make sure to hold your knife at the right angle so that it can catch all of your knife’s edge. It’s important not to press too hard when using an electric knife sharpener—just enough pressure to keep contact with the blade and allow it do its job!

Pros and cons of electric knife sharpener


-Electric knife sharpeners are quick and convenient. They can get rid of a dull blade in just a few minutes.

-The knife is held in place while it’s being sharpened, meaning that you don’t have to worry about accidentally cutting yourself or dropping the knife on your toes. You can also do other things while the knife is being sharpened, like chopping vegetables or watching Netflix.

-Some electric sharpeners come with safety features like non-slip mats and automatic shut-off after 30 minutes of use. This means that if you forget to turn off your electric sharpener before leaving it unattended, no worries! It will stop after 30 minutes and save your battery life.


-Electric sharpeners can be expensive. If you’re looking for something more affordable, try using a manual sharpener instead (though these have their own set of pros and cons).

How to use electric knife sharpener?

If you want to get the most out of your electric knife sharpener, it’s important to know how to use it properly.

We’ve put together a quick guide for you to reference next time you’re looking to sharpen your knives:

  1. First, wash your knife with warm water and dish soap, then dry it with a soft cloth. This will ensure that the blade is clean when you begin.
  2. When you’re ready to sharpen, hold the knife at a 20-degree angle in front of the sharpener’s slot. The slot should be facing away from you and toward the ground (as if you were holding it while slicing meat).
  3. Push down on the handle until you hear a click, which means that the blade has been locked into place. Then go ahead and pull back on the handle to initiate sharpening! After five pulls, remove the blade from the machine and inspect for any remaining burrs or rough spots; repeat steps 2-4 until those are gone too!
  4. To finish the job, you should use a fine-grit stone to polish your knife. This will ensure that it’s shiny and smooth for regular use!

Benefits of using electric knife sharpener

Electric knife sharpeners are a great addition to any kitchen. With the right knife sharpener, you can keep your knives in tip-top shape without having to spend hours honing them by hand. Here are some of the benefits of using electric knife sharpeners:

  1. Electric knife sharpeners save you time and effort. You won’t have to spend hours sharpening your knives by hand, which means you’ll be able to get more done during your day.
  2. Electric knife sharpeners make it easy to get the perfect angle for your blade every time. With an electric knife sharpener, all you have to do is set it up and let it do its job—you don’t have to worry about finding the optimal angle for each individual blade on your own!
  3. Electric knife sharpeners will help extend the life of your blades by keeping them sharpened all the time! This means that instead of having to replace them every couple months when they start dulling down too much, you’ll be able to keep using them for much longer periods of time without needing any kind of maintenance work done first .
  4. Electric knife sharpeners are much safer than traditional manual sharpeners. You don’t have to worry about cutting yourself or getting hurt while using one—they’re completely risk-free!
  5. Electrical knife sharpeners are easy to clean because the blades are self-contained and sealed away from the rest of the machine. This means that any messes that occur will be contained in one area rather than spreading across your countertops and cabinets.

Types of knife sharpener

Electric Knife Sharpeners

These are the most common type of knife sharpener. They range from inexpensive to very expensive, but they all work according to the same basic principle: they use a grinding stone or ceramic rod to grind away metal from the blade of your knife until it’s sharp enough again. Some models have multiple stages with different grades of abrasives so you can choose how coarse or fine you want your edge to be. Electric knife sharpeners are fast and easy to use, but they tend to be expensive and don’t always do a great job on serrated blades or knives with a particularly dull edge.

Sharpening Steel

The sharpening steel is one of the most common types of knife sharpener. It is used to maintain the edge of your blade and prevent it from getting dull. It is also used to hone or straighten the edge of your knife if it has become bent over time, or if you have accidentally bent it while using it. You can purchase a sharpening steel at any hardware store or kitchen supply store, or you can make one yourself by using a piece of metal rod (such as iron) that has been cut into a long strip and then wrapped in leather on each end so that you can hold onto it easily while using it.

Knife sharpening systems

Knife sharpening systems are the most common type of knife sharpener, and there are several different types that can be used for this purpose. The most common knife sharpening system is a sharpening steel, which is a long metal rod with a handle on one end and a tapered diamond tip on the other end. You run your knife along this tapered edge to sharpen it. However, you should not use this method on expensive knives or knives made out of expensive materials like stainless steel because it could damage them permanently.


Whetstones are another popular type of knife sharpener, but they are less common than knife sharpening systems. These stones are usually made out of natural materials like sandstone or ceramic, and they come in many different shapes and sizes depending on what kind of knife you want to sharpen. You place your blade on top of these stones and then draw it across them using short strokes in one direction only (never back and forth).

Handheld Sharpeners

Handheld sharpeners are small enough to fit in your pocket or bag, making them easy to carry when you’re traveling or spending time outdoors. These types of sharpeners typically have two sides: one side has ridges that create a serrated edge on your blade; the other side is flat and smooth so you can hone out any nicks on the blade’s edge. The ridges on these types of sharpeners resemble those used on serrated knives—they cut into the steel of your knife as you pull it through them, creating a new cutting edge where there was once only smooth metal.

Factors to consider when choosing electric knife sharpener

Choosing a good electric knife sharpener is not an easy task, especially because there are many factors you need to consider. In this article, we will discuss some of these factors and help you choose the best electric knife sharpener that suits your needs.


The price of an electric knife sharpener depends on several factors. The first thing that impacts price is the size and weight of the machine itself. A larger machine will be more expensive than a smaller one, because it has more parts and materials needed to make it work properly. The second thing that impacts price is how many different types of knives can be sharpened with a particular machine; if it only sharpens one type of blade, then there will be fewer components to manufacture and less labor involved in assembly processes (which means lower costs).


Another factor to consider when choosing an electric knife sharpener is brand name recognition; some brands have been around longer than others and therefore have established themselves as leaders in this industry through their reputation for quality products delivered consistently over time while still offering competitive prices compared with other brands which may not have been around as long but offer similar products at higher prices.

Intended Use

The next thing you should consider when choosing an electric knife sharpener is how you plan to use it. If you plan on using the electric knife sharpener only for occasional home use, then a less expensive model will likely meet your needs. However, if you plan on using the electric knife sharpener frequently for commercial use in a restaurant or food truck setting, then choose an electric knife sharpener with higher-quality features and components that can withstand frequent use and heavy-duty tasks like slicing through thick steaks or other dense foods.


Another important consideration when choosing an electric knife sharpener is safety. Make sure that the product comes with a safety lock feature so that it won’t turn on accidentally while in storage with other kitchen appliances or items that may also be plugged into electrical outlets (like blenders). Also look for models that have built-in guards to protect fingers from moving parts and blades while they’re being used.

Ease of Use

One of the most important factors to consider when choosing an electric knife sharpener is how easy it is to use. You want something that’s super-easy, and that you can figure out without even reading the instructions (or even looking at them). Look for one that has a simple, straightforward design with no unnecessary bells or whistles you don’t need.

Ease of Cleaning

Another important factor is how easy it is to clean your new electric knife sharpener after using it. Electric sharpeners are often not dishwasher-safe, so you need to be able to clean them by hand. If the knife sharpener has lots of nooks and crannies where gunk can get stuck, then this will make cleaning more difficult. Look for one with a smooth surface and simple design that doesn’t have any hard-to-reach spots where food could get stuck.


The angle at which you sharpen your knife is important because it affects the sharpness of your blade. It also affects how long it takes to get the job done. You want to make sure that your electric knife sharpener can accommodate this variable by having a wide range of angles to choose from. If you don’t have many options, then it will take longer for you to get the perfect angle and finish sharpening your knife.

Slots and Sharpening Stages

Make sure that you choose a model that has multiple slots and stages so that you can achieve the exact edge that you desire for each type of cut. For example, if you’re using it more often on delicate meats like fish or poultry then a fine edge will work best for those types of foods but if you prefer using it on tougher cuts like brisket then a medium or coarse edge would be better suited for those types of cuts instead.


Electric knife sharpeners are made from different materials. Some are made of stainless steel, others are made of plastic, and some are made of aluminum. The material used for the electric knife sharpener will determine its durability, ease of cleaning and maintenance, and price. High-quality models made of stainless steel usually cost more than those that are made from other materials. Stainless steel is durable and easy to clean because it can be washed in a dishwasher. Plastic models are cheaper but tend to break or lose their edge quickly if not cared for properly. Aluminum models are lightweight and easier to handle than models made from stainless steel, but they tend to chip easily when dropped on hard surfaces such as concrete floors.


The type of sharpener that you choose should be easy to maintain so that it will last longer and perform better over time without requiring much effort on your part beyond washing it after each use (if necessary). Most electric knife sharpeners come with a base that must be cleaned regularly so that food particles do not clog the blades or prevent them from working properly when needed most urgently during meal preparation times when everyone’s hungry!


The next factor to consider when choosing an electric knife sharpener is the longevity of the product. If you are planning on using an electric knife sharpener on a regular basis, you want to make sure that it is built to last.


Another important factor to consider when choosing an electric knife sharpener is its versatility. You want a product that can be used with all kinds of knives, from steak knives and kitchen utensils to hunting knives and pocket knives.


You want something that is going to last and be able to withstand the test of time. The durability of an electric knife sharpener is one of the most important aspects because if it breaks down after a few months, then it’s not worth the money.


Another thing to think about when choosing an electric knife sharpener is sustainability. This means that you want something that will last for years without having to replace any parts or spend more money on repairs.


A good warranty will protect your investment if something goes wrong with your knife sharpener. You want to look for a company that offers a warranty that lasts at least 5 years, so that you can feel confident that your investment will be protected if something goes wrong with the product.

FAQs about best electric knife sharpener

How often should I use my electric knife sharpener?

The best way to maintain your knives is by using an electric knife sharpener regularly—once every few months seems like a good rule of thumb for most people. This will prevent them from getting too dull and making food preparation more difficult than it needs to be!

Are knife sharpeners bad for knives?

No, but you should use them only as a last resort. The main problem with knife sharpeners is that they remove too much material from the blade, which can make the knife more brittle and less safe.

But if you have an expensive or particularly high-quality knife, it’s best to let someone else do the sharpening for you (like a professional).

How long do electric sharpeners last?

Electric sharpeners last anywhere from 2 to 6 years on average, depending on how often you use them and the quality of materials used in their construction. They are also more expensive than manual models, so if you’re looking for something that will last longer than your lifetime, then we recommend investing in an automatic model instead of going with an electric one.

Do professional chefs use electric knife sharpeners?

Yes, they do. In fact, many professional chefs prefer the precision and control that an electric knife sharpener offers over manual models. They also appreciate that electric models are faster to use than their manual counterparts.

If you’re looking for a specific type of sharpener, make sure to check out the packaging or the manufacturer’s website before buying.

Do pull through knife sharpeners work?

Yes! Pull through sharpeners are very simple and easy to use—just run the blade across the sharpener a few times and store it between uses. If your blade is dulled down from being used over time, it may take several passes with a pull through sharpener before you notice any improvement in its appearance or function.

Are electric knife sharpeners better than manual?

In general, yes. Manual sharpeners are simply not as effective as electric ones. Manual sharpeners require you to hold the blade at a specific angle and pull it through several times, which can take a lot of time and effort.
