Selecting the best electric knife sharpening system for your own personal use can be a lot of work!
If you’re new to electric sharpeners, then you may be amazed at the sheer number of products that are on the market. To further complicate matters, the price range is massive and extends from the bargain bin to spending hundreds, and that’s even before you get to the best commercial options.
Our mission with this project was to test most of the top-rated electric knife sharpeners available. Not only did we want to create accurate electric knife sharpener ratings that you could rely on, we wanted to do it within the context of price so that you could make choices based on your available budget.

#1. The Best Overall: Chef’s Choice 15 Trizor XV
The Trizor XV is a superb, reliable machine that challenges even many commercial options but at a much more household-friendly price. It employs a “3-stage Edge Select” sharpening system to deliver a perfect edge for whatever the cutting task, and the first and second stages employ 100-percent diamond abrasives. A patented system helps not only polish your knives but prolong the life of serrated edges.
What makes this the best electric knife sharpener is that not only is it precise, durable and built with quality materials throughout, but it’s super-easy to use. It does an excellent job of holding the blade steady so even as a novice when your hand is unsteady, your blades will come out fine.
Another aspect that makes this the best electric knife sharpener for kitchen use is that it’s fully capable of sharpening serrated blades. It even serves as a honing rod into order to ensure that the teeth are in ideal alignment. Serrated knives will cut better, and the teeth won’t be prone to breaking.
The first time you sharpen a knife with this appliance, sharpening takes a minute, more or less. Then, if you keep up with those blades, you can re-sharpen them to a perfect edge in just about 10 seconds. This is a huge benefit when you’re preparing a meal and need a knife re-edged quick.
Dimensions is also what makes this is a top-rated knife sharpener for us. It weighs under 5 pounds and is just 10 inches long. It also comes with an excellent three-year warranty, and Chef’s Choice has a fantastic reputation for doing right by its customers when something isn’t right.
This product is also the best electric knife sharpener available right now and among the best electric knife sharpeners for Japanese knives as well.
#2. The Best High-End: Work Sharp Culinary E5
High-end may be a bit of misnomer depending on your perspective.
One of the excellent features you get for the extra money you’ll pay over the Trizor XV is a built-in vacuum. Probably not absolutely necessary for most users, but it’s a nice touch that collects sharpening debris and keeps your work area clean. Although never sharpen near food regardless!
The E5 also provides a Shape setting in addition to Sharpen. Sharpen is the default, and Shape is the most powerful designed to correct edges that are very dull. This is an area where this model really stands out because it saves a lot of time with really worn knives. Of course, once you have a sharpener and keep up with maintenance, this mode may or perhaps should become less useful over time.
In our review of electric knife sharpeners for home use, this was the non-commercial product that felt most suitable for a professional kitchen. Our team also found that it may be the best electric knife sharpener for shun knives, but the Trizor XV is probably neck and neck here.
Another advantage it has over the Trizor XV is size. It weighs just 2.5 pounds, but perhaps more importantly, it measures just 7.2 by 4.5 by 5.2 inches, which is quite impressive.
#3. The Best Mid-Range: Chef’s Choice 290
The Chef’s Choice 290 may be the best electric knife sharpener for the money!
It certainly is the best electric knife sharpener for mid-range, and as we progressed through our electric knife sharpeners reviews, we immediately identified this as the product that may be the most popular among our readers.
The price point is right in line with a lot of other handy appliances that people have around the kitchen, and the average person probably doesn’t want to spend too much on a sharpener.
You don’t sacrifice much with mid-range here. You’re still getting a three-stage system that uses 100-percent diamond abrasives. Additionally, it can handle serrated as well as about eight other edge types. The Chef’s Choice 290 can sharpen a lot of different knife styles too, including fillet knives, hunting knives, pocket knives, scissors and even machetes and axes!
Consumers don’t even have to sacrifice in the countertop or shelf space department. This unit weights less than 3 pounds and is just 9.9 inches long, which really isn’t bad at all.
There’s a lot to like here, so what’s not to like? Well, it really just comes down to the work load you’ll put on your sharpener. For the quick sharpen here or there, then this is among the best electric knife sharpeners around. If you have a lot of dull knives to correct or will be sharpening frequently, then you’ll definitely getting your money’s worth by moving up just in terms of time saved.
#4. The Best Economy Option: LINKYO Sharpening System
This sharpening system from LINKYO is easily the best electric knife sharpener under budget!
It’s worth pointing out that this is only a two-stage sharpener. Single-stage appliances didn’t make our list, and this is the only two-stage product to make it, and it’s all about the price. The first stage reshapes, sharpens and rejuvenates the edge, and the second stage hones and polishes.
This is a great starter appliance for the bachelor/bachelorette or newly married couple. Performance is quite excellent for a product that costs a fraction of what the other items on our list do. Sure, the speed at which this sharpener operates leaves a little to be desired, but it’s a sacrifice that we can live with. We also like that LINKYO managed to conserve counter space. The appliance only weights 2.65 pounds and measures under 10 inches in length.
Clean up is very simple as well. You’ll just need to wipe it with a damp cloth when finished. Then, from time to time, empty the receptacle that collects the metal shards.
There are some cons as you’d expect in the budget range. Only certain knife and edge styles are supported. You can’t sharpen serrated blades or scissors, for instance. Another concern is durability. This product does feel plastic-y, and a few years of life may be the best that you can expect.
#5. The Mid-Range Runner-Up: Work Sharp Ken Onion Edition
Our mid-range runner-up is the Ken Onion edition from Work Sharp.
We love this machine in so many ways but perhaps none as much as its aesthetics. That may seem a bit shallow, but this sharpener just oozes cool. It would fit right in in a workshop, and it’s actually perfect for that since its among the best electric knife sharpeners for hunting knives and among the best electric knife sharpeners for pocket knives and all other manner of utility knives.
For kitchen use, the aesthetics are probably going to be polarizing. It’ll look out of place certainly. Perhaps that doesn’t matter if you keep it under the counter most of the time, but it’s not an appliance you’ll want on the counter to add to your modern or even rustic kitchen theme.
All this talk of looks aside, this is a fantastic tool in terms of sharpening. It’s not just the best electric pocket knife sharpener. It can sharpen just about anything: kitchen knives, serrated knives, fillet knives, scissors, gut hooks, axes, hatchets, shovels and even lawn mower blades!
Work Sharp even sells handy belt replacement kits so that you can keep your appliance running like new but also tailor it to the tasks at hand. Options include diamond, coarse, fine and even assorted.
There’s really a lot to like about this product, and the price is incredible to boot. As mentioned, it may not be the best kitchen machine—it’s even a bit long at 11 inches. But if you have somewhere else to set it up and use it, then you really can’t go wrong with the Ken Onion edition.
#6. The High-End Runner-Up: Wusthof 3-Stage
Our high-end runner up is the 3-Stage PEtec from Wusthof.
This product came about through a collaboration between Wusthof and Chef’s Choice. The idea was to make the best electric kitchen knife sharpener specifically for Wusthof knives. As we’d expect from Chef’s Choice, the result is much more versatile than that. If you have these German-made knives, then great, but even if you don’t, this is one of the best automatic knife sharpeners on the market.
So, what makes this Wusthof-specific? Well, it has to do with Wusthof’s Precision Edge Technology or PEtec blades. This edge according to Wusthof is difficult or perhaps impossible to maintain with even the best-rated electric knife sharpeners. Enter this collaboration.
Whether that claim is true or not, we’re unsure. We were testing the best electric knife sharpeners of 2018 – 2019 after all—not the best knives. What we did notice was that this was a superior machine that worked well with all of the non-PEtec knives with which we tested it. It was particularly effective with fillet knives and scored well as being among the best electric knife sharpener for fillet knives that we tested.
The black finish with stainless steel accents gives the appliance a strong modern look. If we have one complaint, it’s the size. It measures 12.2 by 6.3 by 6.1 inches, and that’s quite large compared to many of the comparable sharpening systems that we tested.
#7. Honorable Mention: McGowan Diamondstone
The Diamondstone electric knife sharpener from McGowan is consistently among the best-reviewed electric sharpeners with expert sources. This includes Consumer Reports but also outfits that specialize in reviewing culinary accessories for both home and restaurant use.
The biggest issue that we had with this product—and something that other reviewers noted as well—was the sheer amount of sharpening dust that it creates. It was considerably more than all of the other products that we tested, and it’s the reason it dropped down to this honorable mention spot. It’s unfortunate, but we think this messiness will be a deal-breaker for a lot of prospective buyers.
What we did really like about this product and what we think makes it one of the best electric knife sharpeners is that it’s very fast. First sharpens take well under a minute, and re-sharpening takes mere seconds. It does this while still being very accurate and delivering a fantastic edge every time.
Our team did find the design a bit awkward. It’s not ideal for particularly long blades, and we were having to have a second team member hold the unit in position as another held the blade. But this was only with the longest kitchen knives so may only be a hassle every so often.
Size is great. It weighs just 3.52 ounces and measures 8.2 by 7 by 6.2 inches. If looks matter, this model leaves a bit to be desired. The Silver Edition—which seems to be more expensive often—is the best-looking, but the black model is dull and the white model looks very outdated from current standards.
How We Tested and Selected the Best Electric Knife Sharpening System
Testing the best home and the best commercial knife sharpeners was among the most straightforward reviews we’ve conducted in a while. Everyone on our team is an adult who has a lot of experience in the kitchen and with using the best knife sharpeners both electric and manual.
We also wanted to test a wide range of products. Our team tested many different commercial options so that we had that point of comparison. It was also important that we sample not just the most popular electric knife sharpening systems but the most popular across a wide range of price points.
Are Electric Knife Sharpeners Safe?
Absolutely. In fact, these electric appliances are safer to use than manual options because there’s very little chance of slipping and cutting yourself. Nevertheless, all electric appliances must be used with proper precautions and adult supervision. With that in mind, here are five safety tips to consider:
- Read the owner’s manual. Read it all from front to back at least once. These devices seem simple and it’s easy to disregard that information, but most common mishaps can be avoided with this knowledge.
- Never use electric knife sharpeners around water. Don’t use them with lubricants either. Preferably, use them with a GCFI outlet or similar, which will shut down power if an unintended path is detected.
- Stick to the intended use. Not all top electric knife sharpeners are intended for all knives. Your kitchen sharpener can’t necessarily handle your hunting knife or your pocket knife or so forth.
- The best electric knife sharpener in 2018-19 have a polarized plug. The plug will only fit in one way. Don’t force it. If your outlets are incompatible, call an electrician for what is a relatively inexpensive job.
- Every electric knife sharpener is intended for indoor use only. This often happens to the kitchen, so be very careful about using it around hot surfaces—such as a stovetop—that could actually melt the cord.
Can Electric Knife Sharpeners Damage Knives?
Not all sharpeners are made the same. While the answer to this question is yes, it’s important to understand that the best knife sharpening system will not damage knives they’re intended to sharpen.
The sharpeners that do tend to damage knives are cheap automatic knife sharpeners that have but a single stage. These products are often found in discount stores or are sometimes integrated into electric can openers and the like. All of the products we tested and selected are multistage and safe.
Can I Sharpen the Blade on an Electric Knife?
Yes. Absolutely. In fact, one of the pervasive and frustrating misconceptions when it comes to kitchen knives is that electric knives don’t need sharpening and that they can’t be sharpened.
While its true that electric knives tend to hold edges longer than traditional carving knives because of the serrated edge and more uniform motion, those edges do wear down over time. Just make sure that the sharpener you use supports serrated edges, and most of the best power knife sharpeners do.
In addition, remove the blade from the machine. It’s much easier to control this way and you gain access to the entire edge. At this point, follow the guidelines for any serrated edge, which can be a bit trickier, so be sure to read your user’s manual and watch a video online if need be.
Among the most frustrating challenges faced in the kitchen is grabbing a favored knife only to realize that the edge is worn and you’ll have to work harder or use another knife. With a top-rated electric knife sharpener on hand, it will take just a minute or less to get that knife sharpened like-new.
