The Best Knife Sharpeners 2019 – Review of the Top 10 Picks

Finding the best knife sharpener is rarely at the top of the priority list when someone plans to get themselves geared up for the kitchen. But sooner or later, even the strongest kitchen knives will start losing their edges, leaving rags and tears on the cut. If you’ve invested in a quality set of knives, it only makes sense to also find a sharpening device that will help maintain those blades properly.

Finding a decent knife sharpener can be as tricky as finding a decent knife. For one thing, some sharpening devices only work on specific types of knives. Also, the sharpness level delivered depends on not only the quality of the sharpener itself, but also how much time and effort you have spent on the sharpening process.

First things first, let’s take a look at the different kinds of sharpening devices and decide which will best suit your needs.

The Most Popular Types of Knife Sharpeners

These are the best types of sharpening gadgets for kitchen knives.

Pull-through Sharpeners

Pull through sharpeners come in two types: electric and manual devices.

The electric machine typically has a motor that, when on operation, spins the sharpening wheels to reform the blade as you pull your knife through it. It usually consists of a coarse sharpening slot with diamond, stone, or mletal abrasives, and one to three fine honing and polishing slots with diamond or ceramic abrasives.

Electric sharpeners are fast, and very easy to use. They are ideal gadgets for cooks who need sharp knives but don’t want to spend too much time on removing metal chips and straightening their blades.

A manual pull-through sharpener looks similar to the electric machine, except that it has no motor. You sharpen your knives by placing them into the slots and pulling through with force. These manual sharpeners obviously cost less money, and inevitably more time and labor than the electric counterparts. However, they can still bring very satisfying results.

Sharpening Kits

A sharpening kit offers ultimate customization: it typically has several options of coarseness levels for sharpening, and also guides so you can sharpen your knives to the exact desired angles.

Sharpening kits or systems can be manual or electric. They tend to require more time and effort than other simple sharpeners, and you always have to pass a learning curve before you can properly sharpen your knives without causing damages on the blades. A good sharpening kit is totally worth it though: once you’ve mastered the technique, your blades can have even keener and sharper edges than when they’re fresh out of the factory.

Sharpening Stones

Up until a generation ago, a set of sharpening stones was still a must-have item for any cook who wanted to be considered seriously. The act of dragging a blade against a stone was seen almost as a sacred ritual performed only by the master of a household.

Even with the emergence of super effective electric machines nowadays, whetstones and oil stones still enjoy a special favor from knife-enthusiasts for their excellent ability to repair and completely transform dull blades, and also for the sense of accomplishment one feels when the time and effort spent are reflected on the mirror-like blade.

Honing Rods

The honing rod, also called the sharpening rod, is probably the simplest tool in the world of sharpeners. To improve the sharpness of your blades, you run them along the rod at a specific angle.

Contrary to popular belief, these rods can not only give your dull blade a good polish, but with proper materials (diamond for example), they can actually repair mildly damaged blades.

That’s why we spent time checking out the most well-loved knife sharpening devices currently on the market, and picked out the ones we think offer the best performance to review.

Here are our picks for the Best Knife Sharpeners 2019.

1. Chef’ Sharpener CS-T01 3 Stage Knife Sharpener – Best to Buy in 2019

Built in a simple, straight-forward design to repair, sharpen, and hone your blades, the Chef’s Sharpener handheld sharpening device offers a quick yet long-lasting fix for dull kitchen knives without bleeding your wallet.

This is one of the heaviest and best constructed pull-through sharpeners we have ever had in our hands. It’s made of solid ABS plastic, with stainless steel covers at both the working area and the base for enhanced durability and ease of cleaning. It’s a solid piece of equipment, and it shows.

You will also notice two patches of what looks like silicon under the base. These are not sticky, yet they do an excellent job at keeping the sharpener firm at its place on the countertop. This helps prevent slipping and thus any possible accidents while you’re working on your knives.

A moderately damaged blade should go through three sharpening stages: coarse diamond dust rods for the fixing of the knife edge, tungsten carbide blades for deburring, and ceramic rods for fine honing. Give it a few proper pulls at each round, and your knife will come out reset to factory sharpness.

For a fine polish of the blade before and after every use, running it five to eight times through the ceramic rods will do. If you’ve ever tried honing your knife with the base of your china bowl, these rods have about the same effect. They subtly refine the blade, giving it a “sweeter” cut without removing a recognizable part from the edge like the two coarser stages would. As a bonus: you don’t need to place your beautiful bowl upside down on the countertop for this!

Coming with both substance and style, and offered at an unbeatable price, the Chef’s Sharpener is our favorite so far when it comes to picking the best knife sharpener. Even the former hardcore bowl sharpeners in our team appreciate this device. We thought you may also see its value.

2. Chef’sChoice XV Professional Knife Sharpener – Best Electric Sharpener

It was easy for us to pick the best electric knife sharpener to buy in 2019: the whole team were unanimous in our favor of the Chef’s Choice Trizor XV. We love that it’s easy to use, and yet so effective and powerful.

The Trizor XV is designed to bring back factory sharpness to your knives. It features three stages of blade reformation, with two diamond abrasives for coarse and fine sharpening, and a flexible abrasive system for a final polish. It’s not only a good knife sharpener, but one of the very rare out there to offer barber strop style polishing.

The little gadget is also one of the few that are powerful enough to turn your 20 degree edges into 15 degree, hence the name XV. According to Chef’s Choice (and common physics understanding, for that matter), the smaller angle, which is usually found on Japanese knives, allows the knife to cut more easily and perform better than the traditional 20 degree edged knife from Europe and the U.S.

You will indeed feel a sharp difference in how easily your knives cut after being sharpened with the tool. And that’s not only because they have smaller angled edges. The fine sharpening and polishing stages remove all the little chips and create very fine grooves on the blades, allowing them to go smoothly through the toughest materials and leaving minimal tears behind.

All that and the machine is very easy to use. You may want to take a look at the manual first for instructions on how to treat specific kinds of kitchen knives, but it’ll take no time before you get the hang of it.

3. Work Sharp WSKTS-W Knife & Tool Sharpener – Best Knife Sharpening System

We were a bit torn between this and the Ken Onion when picking out the most well-rounded knife sharpening system, but victory finally fell to this more basic edition of Work Sharp sharpener. The reason is simple: it still does all the work, though taking a little more effort, and is offered at half the money required for the Ken Onion.

If you’re new to the knives and tools world, both are Work Sharp electric sharpeners that tackle kitchen knives, outdoor knives, and a plethora of other tools.

As a basic version, there is only one speed option on this machine. It has guides for different angles, but the guides can’t handle 15 degree Asian blades. You will have to learn to sharpen your Japanese santoku without any guide.

On the other hand, the package still includes nine belts in three coarseness levels. The Coarse belt is for thicker tools or really dull blades, the Medium for normal kitchen knives, and the Fine for sharpening serrated blades or honing.

If you’ve only used rods and manual handheld sharpeners all your life, expect a learning curve with this professional knife sharpener. While there are guides to help you get the exact angles, it’s still very easy to get your blades scratched. Or worse, your knife may come out with a damaged edge, especially when you use the coarse ring. We recommend starting with your cheapest knives until you’ve gotten used to the work.

Even then, use the coarse ring only for thick, very dull, or severely damaged blades. Your delicate kitchen knives shouldn’t be rubbed against it more than twice a year.

Worksharp is a veteran in sharpening tools, so it shouldn’t come as a surprise that your knives will be razor-sharp after the process (sharpening and honing). And, like many users have admitted, you will become obsessed with the sharpness and will start looking for and pulling out every kind of blade in and around the house to work on. It does serious sharpening, and is worth both the money and the time spent learning how to work with the little beast.

4. Sharp Pebble Premium Knife Sharpening Stones – Best Sharpening Stone

Looking for a quality sharpening stone for your kitchen knives? Chances are you will be pleased with this Sharp Bebble kit.

The Sharp Bebble whetstone sharpener comes completed in a bundle with everything needed for your ultimate sharpening experience. There’s the double stone, a beautiful holder, and an angle guide which also has its own holder.

Let’s start with the most important item: the stone.

For the sake of convenience, it’s a combination of two waterstones. The blue part, which has a grit (aka grain density) of 1000, is for sharpening dull blades. The white side, meanwhile, has a 6000 grit for honing the knives. This is the perfect grit duo for the knife-sharpening newbie and the expert alike. With this design, I personally believe it is also one of the best chef knife sharpeners you can get, and easily the best for the money.

Note that since a 1000 grit is quite coarse, you are not supposed to use it very often. Once every four to six months would be sufficient. The time between the sharpening is longer if you hone your knives frequently (once every several uses with the fine stone, or every use with a rod).

The bamboo holder seems solid, durable, and is slip-resistant as long as you don’t push it with too strong a force. It’s completed with a silicon “rack” on the upper side, where you can place your stone on for extra stability. The rack also offers some ventilation, which comes handy when you leave it there without first wiping it dry.

The set however, is not without flaws. While most customers find the guide rod useful, there are complaints that it leaves marks and scratches on their knives. You may want to try it out on your less expensive blades first, or if you’re familiar with stones, you may as well ignore the guide altogether.

5. Smith’s PP1 Pocket Pal Multifunction Sharpener – Best Pocket Knife Sharpener

Compact, affordable, and yet multifunctional, the Pocket Pal from Smith’s is a great pocket knife sharpener for your outdoor activities.

While so compact it can fit easily into your jeans pocket, the sharpener is also a mighty one. It has a rear rod coated with diamond that can fold neatly into its shell. Since the rod is tapered to a very small point at its tip, it can slid into the narrow space between the teeth on your serrated knife and sharpen them properly.

The Pocket Pal also comes with two sharpening slots for quick sharpening. It has a coarse one made of carbide to quickly give a new edge to a dull straight blade, and a fine one made of ceramic to give a smoother hone. This ceramic slot can work on both straight and serrated knives alike.

Thanks to its three sharpening options, the Pal can deal with essentially any type of pocket blade, from the toothy hunting knife to the straight camping pocket knife. Theoretically, it can tackle bulky swords or cleavers just fine, but that’d be too time-consuming to be considered a practical option.

The Pocket Pal is super easy to carry around on your fishing or camping trip obviously. And with a concave grip, it’s foolproof too: you will immediately know how and where to hold it properly. It’s small and may feel awkward if you have very big hands, but that’s the price you pay for having something so portable.

6. Lansky Deluxe 5-Stone Sharpening System – Best Manual Knife Sharpener

This Lansky manual knife sharpener kit is not going to be everyone’s cup of tea. If you want to hone your knives quick so you can focus on the cooking, it’s probably not your tool. But if you do find the joy in spending time giving your blades new razor-sharp edges, you will definitely fall in love with it.

The kit comes in a neat box with, among other things, 5 stones of different levels of coarseness and interestingly, different colors, making it look like a playkit.

And it is fun to play with, to the point it may be addictive.

Just take a look at this video.

For all the coolness and artsiness the sharpening process promises to make you look and feel, it’s not even that complicated. With guide rods and a knife clamp, the kit allows you to easily sharpen your knives to various angle options with satisfying precision. It hones basically any type of knives: chef’s, butcher, fillet, and even knives for hunting and outdoor uses. There’s a small bottle of honing oil included, just to complete the set.

If the Chef’ Sharpener is the best handheld knife sharpener, the Lansky easily makes the best manual sharpening system.

That said, it’s not without flaws. With the smallest angle being 17 degrees, the guide rods won’t be so useful on your new Japanese knives which usually come with edges 13 to 15 degrees. You can sharpen them without the rods, of course, but a decent level of hand stability will be required if you are to sharpen the delicate Asian blades to a consistent angle.

7. Utopia Kitchen 10 Inch Steel Knife Sharpening Rod –  Best Honing Steel

The Utopia wins our vote as the best honing steel to buy in 2019 for 2 reasons: it works, and it comes at a price that can’t be any more reasonable.

If you want to feel like a knight honing their sword before a battle, the rod is the right gadget for you.

It comes in two lengths, so depending on the average length of your knives, you can either pick the 10 inches or the 12 inches long option. (Fun fact: if you’re more than 6 feet tall, you’ll most likely feel more comfortable with the 12. It’s heavier and feels more…adequate in your hands).

Made of carbon steel and plated with a thick layer of nickel-chrome, the sharpening steel feels decently weighted when you pick it up. It has a solid plastic handle with a “bolster” that balances out the weight of the metal part, giving you comfort during the honing process.

There’s also a large ring at the end of the handle, allowing you to hang it on a rack or hook it on the wall. A minor but much appreciated feature, because you will need to hone your knives very often. Keeping it somewhere easy to see and reach will be really convenient.

The rod does what it’s designed to do well. It will straighten the edge and take away the little metal chips, keeping the blade sharp and smooth. Give your blade a few strokes before every use, and you will never have a problem with tough chicken skin or ripe tomatoes again.

Note that while it’s also called a sharpening steel, the thing doesn’t really create new edges on your knives. You will still have to do the real sharpening on more serious tools every six to 12 months. Still, this rod really helps to keep the edges decently keen during the time in between.

Tip: you can clean the rod with cooking oil to avoid rust.

8. Knife Sharpener Electric 3-in-1 Sharpening Machine – Best Electric Knife Sharpener Runner-up

It may not be the most expensive nor the most popular electric knife sharpeners out there, but that doesn’t mean the Grocery Art pales in comparison with any of those on the top. In fact, this little sharpener has some features that are superior to even more expensive items up there.

First, the sharpener has a very small footprint. It can stay on even the smallest countertop without taking too much space.

Simultaneously, it’s also convenient to take it in and out of the cupboard or the drawer, as it’s only 1.32 pounds, or one-fourth the weight of the Chef’s Choice. To make up for the weight, there are suction cups at the base to increase stability.

Small but mighty, this electric sharpener comes with four slots for sharpening and honing your kitchen knives. It also has one for shears and scissors (finally!) and even one for screwdrivers. It does its job very well, giving you a sharp blade after just a couple of pulls.

The little motor runs on electricity via a retractable cord underneath. It does get hot quite quickly (maximum time allowed for constant use is 3 minutes). There will be no problem if you sharpen three or four of your knives in one setting, but do not do bulk sharpening with this.

9. WEN 4270 10-Inch Two-Direction Water Cooled Wet/Dry – Best for Heavy Duty

Looking for a sharpener strong enough to stand heavy duty, fast enough to finish the work without you spending hours, and effective enough to make your tools razor-sharp? You may like the WEN 4270 sharpening system.

This is a heavy duty wet/dry sharpening system, and a well-rounded one too. It features a 10-inch stone for coarse sharpening, plus an 8-inch leather-stropping wheel for polishing your blades.

So you begin with the stone, using the jig and guide for the desired angle, to give a thorough regeneration to your blade. As the stone is highly abrasive (220 grit), you may want to start with cheaper axes, chisels, or thick, heavily damaged knives first until you get the hang of it, or risk leaving ugly scratches on your expensive blades.

You may also want to apply a few dressing stones of lower coarseness levels. I highly recommend the 1000 grit and 6000 grit for the stone for finer sharpening of your thinner, smaller knives. Those more fragile knives would also do better if you sharpen them wet– the water can reduce the heat and act as a lubricant to minimize damages to the edge.

After sharpening with the stone, your blade should now be sharp enough to cut through paper. If you want to give it a final polish though, move on to the stropping wheel. You can do it dry, but some sharpening oil would be of great help. If you have sharpened your knife with fine dressing stones, the blade will shine like a mirror after this.

Weighing 36 pounds, the WEN is obviously not a device for a casual cook to put on their kitchen countertop for a quick hone for their knives. Rather, it’s designed for cooks or outdoorists who own lots of different blades and are keen for DIY work.

10. Smith’s DRET Diamond Retractable Sharpener – Best for Serrated Blades

You don’t usually need to sharpen a serrated knife regularly, but when you do, it’s very, very difficult to find a device that does the job well. The most a normal pull-through sharpener, or a stone or even a sharpening band can do, is to remove some burrs from the pointed teeth, which doesn’t help much. The many teeth on a serrated edge require a tiny device to get in between them.

That’s exactly what the Smith’s DRET is designed for.

The sharpener comes in the shape and size of a pen, with a retractable rod at one end. With its tapered tip, this diamond dust coated rod can get to the smallest concaves between the teeth of your knife, bringing them to their original sharpness. Being so compact in size, it has no problem sharpening gut hooks either.

The Smith’s is great for single or double-bevel pocket knives, sport knives, and most tactical knives.  For small and medium-sized knives whose blades are only partially serrated, this rod can really be a saver. While the tapered part is for sharpening the teeth and/or the gut hook, the half-rounded end of the rod can take care of the straight part of the edge.

It will surely be a bit time-consuming if you use it to sharpen a particularly long blade. However, when there’s serration, it’s technically the only effective way to do it.

When not in use, the rod is kept safely inside the handle. It even has a clip so you can easily attach it to your pocket.

Are You Picking the Right Sharpeners for Your Knives?

Most people have more than one type of knives in their kitchen. Thus, it’s important to get a sharpener that can handle most if not all of the knives.

First, let’s take a look at the two most common types of knives in terms of blade angle.

Western knives, designed for dealing with animal-based foods and sinewy vegetables, typically have a large, strong blade angle at 20 degrees.

Asian knives, meanwhile, made to cut less meat and bones but more fish and softer vegetables, have smaller angles (13 – 15 degrees).

Then, the knives are also categorized based on their blade grinds, or in other words, the shape of their blade. There are flat, hollow, taper, convex, and chisel edges. It is impossible that a simple sharpener can fix and polish all of the types.

If all of your knives belong to a knife set, awesome! Determine if it’s an Asian or a Western set, as well as the type of blade grind, and buy a sharpener with that exact angle.

If you have all the different kinds of knives, from German to Japanese, which is often the case for hard-core cooks, finding one single best knife sharpener can be a bit more complicated. You will either have to get more than one pull-through sharpener, or learn how to work with a semi-manual or fully-manual system (think waterstones, oilstones, Lansky, WorkSharp and the like).
