There is nothing like the satisfaction of a freshly sharpened knife. The clean cuts with almost no ease, making your kitchen experience so much better, is probably one of the best feelings as a chef. I know whenever I have a sharp knife, I am much more inspired to create more dishes with better plating.
The opposite is true, though. Dull knives are uninspiring, knowing there’s a way to slice things easier. It adds a lot to the time and a whole lot to the frustration that sometimes comes when you’re cooking, especially when you’re in a hurry. You are also a lot more prone to accidents with dull knives.
Why don’t I just sharpen my knives all the time, you ask? Well, there are days when cooking just isn’t a priority for me. Sure, I may have some slow days where I am able to enjoy my cooking and treat it as a little way to relax, but most days are hectic, especially on workdays. Sometimes, cooking just is less of a hobby and more of a necessity.
In my attempts to save some time especially in the morning, I set out to find equipment that would inspire me to cook and set the tone for a good day. This was when I stumbled upon electric knife sharpeners. Turns out, it’s not as easy as pointing to the most expensive one and buying it, especially if you take pride in your knife set.
There are a lot of things to consider while buying electric knives. Firstly, at what angle do you want your knives to be sharpened — the Western way or the Japanese way? Is your knife’s material able to sustain this in the first place? Are you using ceramic knives or steel knives?
Keep this in mind as you go through this list of the best electric knife sharpeners. I’m sure you’ll find one that will be perfect for your needs!
You might be thinking of converting your chef’s knife from a 20-degree cutting angle to 15 degrees. The latter is usually the Japanese style of sharpening knives, which are, of course, known to value precision especially in their style of cooking.
The Chef’s Choice 15 Trizor XV EdgeSelect electric knife sharpener is great for this. Of course, there are things to consider before converting your knife, which you’ll see in our buying guide below. Overall, though, users are amazed at how sharp their knives become after using this product.
This is a 3-stage electric knife sharpener, which gets more and more precise as you go through the stages. The first two stages contain diamond abrasives, which are basically bits of diamond incorporated into the sharpening tool. As you might know, diamond is considered the hardest material on Earth, making it great for grinding down your knife’s edges.
The third stage uses a flexible abrasive system, which smoothens the rough edges of the knife that the first two stages might give it. This third stage can be used to polish and prolong the life of serrated knives too, which are knives with toothlike edges such as bread knives!
It’s quite amazing how you can turn your old knives into razor-sharp knives, good as new! However, if you have some knives that you treasure a lot, especially those that cost you a fortune, you might want to steer away from this product. Many users have reported this electric knife sharpener ruining the finish of the sides of their knives with unfavorable scratches. Keep that in mind as you decide on your purchase.
- Great sharpening ability
- Converts 20-degree angle knives to 15 degrees
- Smoothens edges
- Scratches the sides of the knives sometimes
- Quite pricey
This knife sharpener intimidated me at first, and I think it’s meant to be intimidating with the number of features it has. The Work Sharp Knife & Tool Sharpener, as it says in the name, is not only for the kitchen but also for your backyard. Be sure to clean it, though!
The great thing about this knife sharpener is that you can adjust the angle at which you are sharpening your knife. You don’t have to settle for the 20-degrees, or force yourself to get down to 15 degrees if your knife is not as durable as Japanese knives; you can increase or decrease the degree by 5-degree increments.
If you need an option to sharpen your ceramic knives, you can purchase a diamond belt kit for ceramic blades. It features a 180 and 1500 grit, which is great for sharpening your ceramic knives but not making it too thin and vulnerable.
Several belts are included for different types of grit. The higher the grit, the finer your blade will be polished and sharpened. You wouldn’t want to use the higher grits for all types of blades as this weakens the edges, especially if you’re going outdoors, but precise cutting will be great for this.
Some users have reported scratches on the sides of the blades, so they recommend putting some tape before using it. It also sheds some shavings, so make sure you’re in a place that can be easily cleaned up.
- Different belts provide different grits
- Adjustable angles
- Used for all kinds of blades, even scissors
- Scratches the sides of the knife
- Messy shavings
Some electric knife sharpeners are just too complicated. You might not have the time to practice and to learn how to master the product. The Presto 08810 Professional Electric Knife Sharpener does away with that, giving you a simple-to-use product with a professional finish.
With just some buttons and sliders, you can easily choose which kind of grit thickness you need. You can choose from thick, medium, and thin knives. Different knives are great for different thicknesses, of course; hunting knives need the thicker option while the thin option is for lighter blades.
This electric knife sharpener also has 3 stages. The first stage is for getting your blade to the right angle, especially if it’s a very coarse knife. You can use this for your backyard tools as well. The first stage readies the knives for the next two stages, which get finer and finer.
You still have to learn how to use this product, though, as it’s not as simple as putting it through the sharpener and pulling it away. You have to be quite gentle, pulling it at a constant rate for a consistent sharpening. However, it’s not as hard to learn as other sharpeners, which I like.
You might also be bothered by the mess it makes, especially since it causes metal shavings to fall off.
- Great sharpening ability
- Different thicknesses for you to choose from
- Guided angle so you don’t have to move it yourself
- Messy shavings
- Practice needed for consistency
You’d be surprised at how great the Shenzhen Electric Diamond Knife Sharpener is at sharpening your knives at such a low price. You’ll also be pleased to know that this is designed for both ceramic and stainless steel kitchen knives!
It comes at two stages: the first one is for a coarser sharpening at 600 grit, while the second is finer at 800 grit. These aren’t as fine as the others simply because it is designed for ceramic, which is a bit more vulnerable and cannot be sharpened to a thin edge without breaking.
You also won’t have to worry about handling this poorly as it guides the angle for you. It can grind ceramic knife chips for up to 1mm, which makes it close to brand new. This is great because other knife sharpeners actually cause the chipping, especially if you’re going too fine and putting too much pressure on your ceramic knife.
Its diamond wheel can be cleaned easily, too, as it features a removable cartridge. Some users aren’t too happy with how much effort it takes to sharpen the knife with this one, though. You’d have to go through it several times to get it to that point, but that’s actually by design.
Ceramic knives aren’t supposed to go through grinders that quickly sharpen your knife as other electric sharpeners do. Ceramic is much more fragile than steel knives, so you might want to keep that in mind when buying this. However, if you don’t really need a razor-sharp knife, then this is a great product for you.
- Made for ceramic knives and can also be used for stainless steel
- Guided angle
- Can grind knife chips up to 1mm
- Easy cleaning
- Will not grind as finely as other knife sharpeners
Others of you, I’m sure, simply want a basic electric knife sharpener for your kitchen that does the job and does it well. The EdgeKeeper Electric Knife Sharpener is definitely that. It does not have any major extra features, but it is definitely a great product at a low price.
Some electric knife sharpeners do not take into account how you’ll actually be using their product. You know, if you’ve used a knife sharpener, that it’s very important that it stays in place. The non-slip silicone at the bottom of the EdgeKeeper is fantastic at keeping your sharpening experience safe.
Not only do they think about the placement of your knives, but they also think about the cleanup. A removable magnet is included to collect the metal shavings that’ll occur while sharpening.
That being said, this sharpener is designed for steel knives, so it’s best to steer away from this if you like ceramic knives. It has two stages with diamond-coated sharpening wheels, making it great for refining your knives.
If you’re going for a more polished knife set, this might not be for you. Casual cooks such as I tend to gravitate to cooking more basic meals that do not require refined knife skills, which makes it perfect for someone like me.
- Keeps the sharpener in place
- Magnet for easy cleanup
- Relatively low price
- Basic sharpening ability; not too polished
Key Considerations When Buying Electric Knife Sharpeners
You might be confused by the number of features that each electric knife sharpener has. Some create finer edges, but that’s not always the best way to go. Some even take pride in its lesser grits. How do you decide which kind of electric knife sharpener is for you?
As with every product, it really depends on the experience you want to have, depending on your personal preference. I prefer my knives to be just the right sharpness as I don’t really need razor-sharp blades! This allows me to go for cheaper brands that will do the job for me.
Want to know what’s best for you? Keep reading to find out what features you have to keep in mind.
This is definitely the first thing you have to keep in mind when buying electric knife sharpeners. You, of course, have to take into account what would be the best grit or precision for the type of material that your knife is made of.
Steel is most probably the knife you have at home, as it is arguably one of the most common knives. These are very durable knives and are usually seen in professional kitchens as well. However, without the proper care and maintenance, you might find that these tend to rust. Just make sure you clean your knives well and that any liquids are dried off.
These are also quite hard to sharpen, but thanks to tools like electric knife sharpeners, it has become quite easy to polish them into the shape you want for easier slicing. There are, of course, different kinds of steel knives which vary in its ease of sharpenings, such as stainless steel and carbon steel.
Because of its durability, it can also take a finer grinding for a more sharpened knife. This is why you’ll find that electric knife sharpeners such as the Presto 08810 Professional Electric Knife Sharpener will have very fine settings. It can easily be refined into a knife good as new.
Ceramic knives are less durable than steel knives. They are very brittle, but they also rarely need to be sharpened because they keep their shape well. The edge stays sharp for longer. Another great feature is that it does not retain odor and is very easy to clean.
However, due to its fragility, it chips quite easily, making it hard to sharpen. This is why you need to choose your electric knife sharpener carefully. I suggest you go with sharpeners such as the Shenzhen Electric Diamond Knife Sharpener.
Sharpeners such as these are designed to not be as high-powered as others, taking into consideration the fragility of ceramic knives. They only sharpen to a certain degree and thickness.
Type of Knife
The type of blades and knives you have at home really has an impact on what kind of electric knife sharpener you need. You might not only have chef knives and other types of kitchen knives that you need to sharpen and shave off.
Sometimes, you also have gardening tools that need some help from time to time, especially if you want to keep your yard clean. If this is the case, it’s best if you pick a sharpener that is very flexible and will sharpen anything for you, from bread knives to scissors. You’ll love the Work Sharp Knife & Tool Sharpener Ken Onion Edition for this feature!
The angle at which your knife is sharpened is surprisingly important! Most Western knives are sharpened at a 20-degree angle, which is less precise than the Asian 15 degrees. The lower degree makes for a knife that will cut your foods with less drag.
Although you might be tempted to convert your 20-degree knife into a 15-degree one, keep in mind that Western knives are made of much “softer” varieties of steel. This is because the Western style of cooking does not require much precision, but instead wants greater impact.
This makes it harder for Western knives to keep the 15 degrees intact, so you might find that you have to sharpen more. However, you might find that some electric knife sharpeners are great at sharpening quickly anyway, so it won’t be much of a hassle. The Chef’s Choice 15 Trizor XV EdgeSelect Electric Knife Sharpener may help you with this!
This might not be a big consideration for you, but trust me. Loads of reviews have complaints about how messy it gets! This is because you’re not sharpening on a wet surface, and are instead creating friction that shaves off a lot of metal. You might find that this will be a lot more irritating for you than you would expect.
Some electric knife sharpeners try to solve this by catching the metal shavings inside the machine. Some even have removable disks for easier cleaning. The EdgeKeeper Electric Knife Sharpener, for example, has a removable magnet that could make it easier for you to catch the metal shavings.
Frequently Asked Questions On Electric Knife Sharpeners
It really depends on how much you cook, or what level of cooking ability you are at. I, for example, am an amateur chef trying to explore the world of cooking but am in no means a professional. This is why I prefer knives that are just the right sharpness.
If you are a professional, I’m sure I don’t even have to say that sharp knives are needed for your more precise cutting. However, sharp knives are important for any cooking ability level out there, as dull knives tend to be more dangerous than sharp ones.
To put it simply, coarser grits at around 220 grit are for hunting knives, blades that have chips, or knives that are being converted to another angle. A medium grit stone (1000-1500 grit) is for chef knives. They’ll get your knives to not be dull but not razor-sharp either.
A finer stone (4000 grit) will get your knife to a very sharp edge, but still being very durable. Finer than that (6000 to 8000 grit) and you’ll have a very delicate knife that is great for delicate ingredients but dulls easily.
They definitely can, as seen in some reviews. Some electric knife sharpeners tend to be very high-powered, making for a sharper edge but a scratchy knife body. Some brands recommend putting on the sides of the knife before running it through the sharpener.
Sharper knives are, undoubtedly, more inspiring to use than duller knives. This is why electric knife sharpeners are easily one of the best tools for me. It’s a quick and easy way to increase your effectiveness and speed in cooking.
Just make sure you’re always checking the reviews of each product, especially if you take good care of your knives. You also want to see how others struggled with each product and how you can avoid their mistakes. Overall, it’s really all up to you. I’m sure you’re as sharp as a knife in deciding what’s best for you!
