A professional knife sharpener can make a world of difference in your kitchen. Unfortunately, some of them can be pretty expensive and not very easy to find. The good news is that there’s another option! Electric sharpeners are just as effective as the professional ones, but they’re also a lot more affordable.

What is an electric knife sharpener?

An electric knife sharpener is a machine that will sharpen your knives with the press of a button.

This device has a handle, a blade guard, and an electric motor. The blade guard prevents you from accidentally cutting yourself when you’re using the device. It’s designed to stay in place at all times, so you don’t have to worry about it falling off or getting lost while you’re using it.

The electric motor powers the knife sharpener and helps to grind down any dull edges on your knife blade. The motor makes use of alternating abrasive pads (often made from either diamond or ceramic) that move back and forth against your knife as it spins around in its holder at high speeds. This helps to straighten out any bends or other damage that has been done to your knives’ blades over time by chopping through tough foods like nuts or bones which can cause dents in their sides if not removed quickly enough before they become too deep for regular maintenance practices alone (like sharpening).

Benefits of using electric knife sharpener

It is easy to use: Electric knife sharpeners are very easy to use due to their simple design and user-friendly features. You just need to place the knife into the slot, and then turn on the machine. The sharpener will do its job automatically. 

It is safe: Electric models have safety features that prevent your fingers from hurting when using it. Some models even have a lock button so you can keep them in one position while working on other things without worrying about having an accident! 

It’s convenient: Most electric sharpeners come with a cord or rechargeable batteries for portability purposes, which means that you can use them wherever you want without having to worry about finding an outlet nearby!

It’s easy to clean: They’re also easy to clean because all of their blades are detachable and dishwasher-safe; therefore cleaning up after using them will not be difficult at all! Additionally, they take up very little space in your kitchen drawer while still being accessible whenever needed without getting lost somewhere behind other utensils like other manual sharpeners might do over time (or even right away).

Types of electric knife sharpeners

Electric knife sharpeners come in three main types:

-Manual: This type of sharpener requires you to hold the blade in place and move the sharpener across it, as if you were using a whetstone. Manual sharpeners are ideal for people who are comfortable with holding a knife at an angle, but they’re not automatic.

-Pull-through: A pull-through sharpener is like a manual one, but it’s automated. You simply press the knife into the sharpener and pull it back out. Pull-through sharpeners are also ideal for people who want to sharpen their knives quickly and easily with minimal effort on their part.

-Electric: An electric knife sharpener uses an electric motor to rotate two or more wheels that touch the blade simultaneously while it moves through them at varying speeds. These wheels can be made from different materials—some use diamond-coated abrasives while others use ceramic ones—and they usually have multiple stages so you can choose how fine or coarse your blade needs to be after being sharpened.

How does electric knife sharpener work?

An electric knife sharpener uses a rotating abrasive disc to sharpen your blade by grinding the blade against the sharpening rod. The abrasive disc is made of diamond-coated steel, which allows it to grind away material from your blade without losing its edge. A motorized arm moves this rotating abrasive disc back and forth across the length of your knife, allowing you to quickly restore its original sharpness.

If you take apart an electric knife sharpener, you’ll see that it’s pretty simple: there are no moving parts except for a small motor that powers the arm’s movement and rotates both itself and its attached guide rod (the fixed metal bar along which grinding takes place). That said, most models offer variable speeds so that you can choose how fast or slow you want them to run—that is, if they have variable speed options at all!

How to use electric knife sharpener?

To use an electric knife sharpener, you’ll need to follow these steps:

  1. Plug the knife sharpener into an electrical outlet.
  2. Insert your knife into the slot, with the blade facing up and away from you. Make sure it’s centered in the slot so that it fits properly.
  3. Press down on the handle with one hand until you feel resistance against your hand and hear a clicking noise that indicates that your knife has been secured in place by two prongs inside the machine. Then turn on the machine by pressing down on its power button with your other hand.
  4. Once the machine is running, gently draw your knife back and forth across the sharpening slot until you hear a second clicking noise that indicates that all of your knives’ blades have been sharpened (this can take anywhere from five seconds to several minutes depending on how dull they were before). After each blade has been sharpened, run them across a piece of paper to test whether or not they’re now sharp enough for use in your kitchen!

Pros and cons of electric knife sharpener


– Electric knife sharpeners are easy to use, allowing you to simply run the blade through the sharpener and get a perfectly sharpened edge.

– They are very fast, with some models able to sharpen a blade in as little as 15 seconds!

– You don’t need to spend hours trying to get your knives sharpened with an electric model—just let it do all the work for you.

– Electric models usually come with two stages of sharpening—the first stage is designed to remove small amounts of metal from the blade and make it sharper, while the second stage is designed to polish and make the blade look shiny and new again.


– Electric knife sharpeners don’t work as well with duller knives, so if yours are already pretty sharp this won’t be the most cost-effective solution.

Factors to consider when choosing electric knife sharpener

Choosing an electric knife sharpener can be daunting. There are so many options out there and no one knows exactly what they need, so it’s difficult to know where to start.

To make things a little easier for you, here are some of the main factors to consider when choosing an electric knife sharpener:


There are two basic types of materials used in knife sharpeners: steel and ceramic. Steel is more durable but can rust if not cared for properly. Ceramic is less likely to rust or chip, but it also wears down more quickly than steel. You will have to decide which material is right for you based on how often you plan on using your sharpener and how careful you are with it.


The design of your knife sharpener will determine how easy it is to use, as well as whether or not it has any features that will make your life easier (such as an adjustable angle guide). Some models come with built-in storage compartments or magnetized holders for holding knives while they’re being sharpened. Others have slots for holding different types of knives at different angles. You’ll want to find something that works well for your needs!

Types of Blades

There are two types of blades: straight and serrated. Straight blades are used for cutting through meats and vegetables, while serrated blades are used for slicing breads and cakes. If you’re unsure which blade you have on your knife, check the label on the handle or look at the bottom of the blade where it meets the handle; there should be an icon representing what kind of blade it is (for example: “S” for straight).

Electric or Manual

Electric knife sharpeners are usually more expensive than manual options, but they can be more convenient to use. If you don’t want to deal with the work of sharpening your knives manually, or if you don’t have the time or patience to do so, then an electric knife sharpener may be a good choice for you.


When it comes to electric knife sharpeners, you will find that there is a wide range of prices available. The more expensive models typically have more features such as multiple stages, safety features, and larger motors to power through tough jobs like thick steak knives. However, if you are looking for an affordable option that still gets the job done then there are plenty of options available as well.

Number of Stages

The number of stages will determine how much metal is removed from your knife blade during each pass through the sharpener. This can be important because if the blade has too much material removed from it then it may be weakened or broken during use. For most people though, 2 stages should be sufficient enough to keep their knives sharpened without having any issues with durability or performance over time

Sharpening Wheel

The sharpening wheel is one of the most important features to consider when choosing an electric knife sharpener. It should be made of high-quality materials that are durable and will last for a long time. A good sharpening wheel will be made from hardened steel or tungsten carbide, which are both very hard and durable materials. The majority of electric knife sharpeners have wheels made of these materials, but some may also use ceramic or diamond-coated wheels, which are also great choices for durability and effectiveness in sharpening knives.

Angle Guides

Angle guides are one of the most important features to consider when choosing an electric knife sharpener. They help ensure that you’re adequately sharpening your knife, which is essential for keeping it in good condition and prolonging its lifespan. If you don’t have a guide, you could end up with a dull edge, which makes your knife more likely to break or chip.


Safety is another top consideration when choosing an electric knife sharpener—the last thing you want is for your device to cause injury! Some models come with safety features like retractable blades and automatic shut-off options, but many other models don’t have these safeguards, so it’s important to read reviews before making a purchase decision so that you know what kind of safety precautions are available on any given model.


The maintenance of your electric knife sharpener is a crucial factor to consider before you buy one. You don’t want to have to spend time cleaning and maintaining the machine every time you use it, but you also don’t want to have a machine that doesn’t work well and needs constant adjustment.


Another important factor is the longevity of your electric knife sharpener. You want it to last for years so that you can continue using it without worrying about having to replace it right away.


Price is one of the most important factors to consider when choosing electric knife sharpener. It is a good idea to choose a product that has a price that is within your budget. This will ensure that you can purchase an electric knife sharpener without having to worry about going over your budget. The price of an electric knife sharpener is usually determined by the manufacturer, so it may be difficult to find an electric knife sharpener with a lower price than others on the market. However, there are some retailers who will sell their products at a discounted rate if you buy multiple items from them or if you purchase something else from their store as well.


The final factor to consider when choosing electric knife sharpener is whether or not it comes with a warranty or guarantee. A product with a warranty or guarantee means that if something goes wrong with your device within a certain amount of time after purchasing it, then you will be able to get it fixed or replaced by the company who sells it at no cost to yourself. This can help save money in the long run because it ensures that any issues that arise during use will not cost anything out-of-pocket from your pocketbook!

FAQs about best electric knife sharpener

How often should I use my electric knife sharpener?

You can sharpen your knives whenever you want, but we recommend using it at least once a month. This will keep your knives in good working condition, and also make sure they stay sharp. If you use them less frequently than that, the blade will get dull and start to tear your food instead of slicing through it easily.

Are knife sharpeners bad for knives?

Knife sharpeners aren’t bad for knives—as long as you use them properly! We recommend following the instructions for your specific model of electric knife sharpener, especially if it’s one that has multiple stages or settings. You’ll want to be sure not to oversharpen your knives and damage the blade by using too much force when you’re putting them in or taking them out of the machine.

Do professional chefs use electric knife sharpener?

Yes! The majority of professional chefs do use electric knife sharpeners when they need to get their knives back into shape quickly and efficiently. The reason for this is because most electric sharpeners offer more precision than manual ones do–they’re usually made from high-quality materials that ensure sharpening accuracy and also provide safety features such as guards or automatic shutoff mechanisms.

Are knife sharpeners bad for knives?

No, as long as you use them properly! Knife sharpeners are designed specifically for sharpening knives—they don’t work on anything else, and they can damage other types of blades (like scissors). Be sure to read your user’s manual before using your knife sharpener so that you know how to operate it correctly!

Do knife sharpeners get dull?

Yes, but they’re easy to replace! If you have a sharpener that uses a grinding wheel, you can buy a replacement wheel at any hardware store. Most sharpeners that use a diamond-coated steel rod will come with a few replacement rods, but if yours didn’t, you can also find replacements at any hardware store.

What is the best way to sharpen a good knife?

When you’re using an electric knife sharpener, it’s recommended that you keep your hand on the handle of the knife while sharpening so you can control how much pressure is being applied by the machine. If you’re using an old-fashioned manual sharpener, hold your hand over top of the blade and use moderate pressure as you move it back and forth across the stone or rod.

Does rubbing knives together sharpen them?

No, rubbing knives together is not a good way to sharpen your knives. Rubbing them together will actually dull them more quickly, and you’ll have to replace them sooner than if you had done nothing at all.

Can you sharpen serrated knives?

Yes! You can use an electric knife sharpener on your serrated blades as well as your straight ones. The key is finding the right kind of sharpener for your specific type of blade, whether it be a manual or electric model.

How long do electric sharpeners last?

This depends on how often you use them and how well you take care of them! If you use them every day and don’t clean them regularly, they’ll probably last about two years. If you only use them once in awhile and take good care of them (cleaning regularly with water), they’ll last longer than that—maybe even five years or more!

Will an electric sharpener ruin your expensive chef’s knife?

No, electric sharpeners won’t ruin your expensive chef’s knife. In fact, they’re often the best tool for maintaining your knives and keeping them pristine. They have several advantages over manual sharpeners: they use consistent pressure, they don’t require you to get up close and personal with a blade, and they can handle any size or shape of knife.


With the help of a knife sharpener, you can make your knives work like new again. This is something that everyone should know about and have in their kitchen to keep everything running smoothly. They’re not just for professionals who use them every day; they’re also great for keeping your knives in good shape if you’re only using them occasionally or if you don’t want them to get dull or rusty. A lot of people think that this type of tool only exists at restaurants where food is prepared by professional chefs but there are plenty of options available now which make it easy for anyone to get started on their own!
