Finding the best knife sharpener can be as tricky as finding a decent knife. Some sharpening devices only work on specific types of knives. Plus, the resulting sharpness level depends on not only the quality of the sharpener, but also how much time and effort you spend on the sharpening process.
Let’s take a look at the different types of sharpening devices and decide which will best suit your needs.
Every time you use your knife, burrs and chips develop at a microscopic level. These build up little by little, making you spend a tiny bit more effort with every cut. Precision becomes harder to achieve. Before too long, you will find yourself contemplating how to approach the food with your knife without leaving too many rags or tears. Instead of supporting your creativity, a dull knife holds you back in the kitchen.
The Most Popular Types of Knife Sharpeners
The four most popular types of sharpening devices for kitchen knives include honing rods, pull-through sharpeners, electric devices with abrasive belts, and whetstones.
In this graph, we compare them in terms of ease of use, the maximum level of sharpness each device can offer, and their prices.
How to Pick a Knife Sharpener
1. What Grit is the Abrasive?
Whetstones, sandpaper, and abrasive belts are usually categorized by their “grit”.
Grit is abrasive particles or granules of sand, diamond, or other stones. The grit number indicates how coarse or fine the abrasive is. The more grit an abrasive has (the higher the number), the finer it is and the less material it can take off a knife blade.
Abrasives with low grit numbers can remove a lot of material per stroke, and therefore are very useful in repairing heavily damaged knives. Chefs take their knives to them only once or twice a year to rejuvenate the edge. Finer abrasives can be used more often to fine tune the blade.
The grit system is not consistent between different areas, brands and types of material. It is important to follow the instructions from the manufacturer to get the right grit when buying your stones or belts.
Pull-through sharpeners, even the type with diamond or metal dust, don’t typically come with clear grit numbers. On a multi-stage one, the first stage is usually the coarsest and should be applied only occasionally, while the later stages are suitable for frequent use.
2. What Grind and Angle is the Knife Edge?
In terms of edge angle, most chef’s knives are either Western or Asian style.
Western knives, designed for dealing with animal-based foods and tough vegetables, typically have a large, strong blade with a 20- or 22-degree edge. Asian knives, meanwhile, are intended more for fish and softer vegetables, and have finer angles (13 – 15 degrees). Wider-angle blades are stronger, while finer angles allow for more precision.
Some of the top kitchen knives that are hybrids, with edge angle between 15 and 18 degrees.
The knives can also be categorized based on their blade grinds, or in other words, the shape of their blade. These edge styles get the names flat, hollow, taper, convex, and chisel. It is impossible for a single sharpener to fix and polish all of the types. However, the right knife sharpener for you is one that can handle the majority of your knives.
If all your knives belong to a single knife set, it will be easy to find the right sharpener. Determine if yours is an Asian or Western set, as well as the type of blade grind, and buy a sharpener with the same angle.
If you have all the different kinds of knives, from German to Japanese (which is often the case for serious chefs), your search for a 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 a semi-manual or fully-manual tool (think waterstones, oilstones, or full sharpening systems).
3. A Word on Serrated Knives
You don’t need to sharpen a serrated knife regularly, but when you do it’s often difficult to find a device that does the job well. The most that a typical pull-through sharpener, stone, or sharpening band can do is remove some burrs from the pointed teeth, which only goes so far. The many teeth on a serrated edge require a tiny device to get in between them.
There are a select few options for properly sharpening serrations, which we will point out as we get to them.
How Long Should It Take to Sharpen a Knife?
The amount of time it takes to sharpen a knife depends on various factors: your level of skill, the type of sharpening device that you use, the type, size and material of the knife, the knife’s condition, and the desired level of sharpness.
Per our estimation, here’s the time it typically takes to bring a chef’s knife to the maximum level of sharpness that the sharpening device allows:
- Sharpening rods(for honing): 1 – 3 minutes
- Pull-through sharpener: 3 – 4 minutes
- Electric pull-through sharpener: 3 – 4 minutes
- Electric sharpener with multiple abrasive belts: 10 – 15 minutes
- Sharpening stones: 20 – 40 minutes
Reviews of the Best Knife Sharpeners in 2022
We checked out the most popular knife sharpeners currently on the market and reviewed the ones we think offer the best performance.
1. Best to Buy in 2022
Kitchellence 3-Stage Manual
Things We Like
- It really sharpens
- Easy to use, intuitive design
- Soft, comfortable finish
- Extra weight near the base for stability
- Affordable price
- Included glove for added safety
Things We Don’t Like
- Tapered base
- Awkward base pad
The Kitchellence is our recommendation for those looking for a quick, affordable, and well-rounded sharpener for your dull kitchen knives. We’ve repeatedly tested and rated more than a dozen devices, including both manual and electric ones, and this manual sharpener has maintained its place at the top of the rating table without fail.
It did well in our sharpening time test, taking less than 2 minutes to bring a knife from completely blunt to being highly serviceable. And after a couple more minutes, the knife could cut through a chicken breast with skin using two swipes.
There are other manual devices, such as the Smith’s or the SunrisePro, which outperformed the Kitchellence in these areas. However, they removed way too much material from the blade. Those sharpeners also ended up creating rough, toothy edges that were far inferior to those achieved with the Kitchellence. Electric sharpeners, meanwhile, are much more expensive, require more space, and take more time to get used to.
The learning curve is almost flat with the Kitchellence — it has a simple working section with sharpening stages that progress naturally. Its sharpening rods are more substantial than what we see on most devices of its type, and they show fewer signs of wear and tear after half a year of heavy testing in our lab.
The handle boasts an ergonomic shape with finger grooves for a firm, secure grip. Not that you will need much effort to hold the device in place. While its tapered base isn’t ideal, it comes with a metal plate under the working section, which helps a great deal in lowering the center of gravity and ensuring stability.
We also can’t complain about the sharpener’s build quality. It’s solid, sturdy, and has a nice plastic body that feels soft and almost luxurious.
With only one angle option, the Kitchellence is not going to sharpen your filet knife or single-bevel knives. But it will reliably improve most other kitchen knives. And at its affordable price, the device will pay for itself quickly.
2. Best Knife Sharpener - Runner-up
Things We Like
- Excellent stability
- Affordable price
- Consistent sharpness
- Solid and sturdy construction
Things We Don’t Like
- Small ceramic rods
- Flaky brand label
With three stages of sharpening, plus a design that ensures safety, the Cubikook CS-T01 sharpener is a quick, effortless, yet long-lasting solution for your dull knives.
There are devices that sharpen more quickly and to greater sharpness levels, but the Cubikook’s performance is by no means subpar. It also scored some of the highest ratings in our edge smoothness and material retention tests — its results struck a nice balance between sharpness and edge integrity.
The Cubikook CS-T01 also has one of the lowest centers of gravity among all the devices we tested. Its working section is tightly fastened on a wide, flat, and solid base, with two strips of silicone underneath to further stabilize it. This effectively eliminates the risk of flipping or slipping as you sharpen your kitchen knives.
With wide sharpening slots placed in a natural progressive order, the device is easy to use. Just make sure you’re gentle on the white ceramic rods — they tend to become loose more quickly than the other abrasives.
All in all, the Cubikook CS-T01 is a well-rounded handheld sharpening device. We recommend it for every home cook who wants a cheap, effective sharpener that’s also safe, quick, and doesn’t require too much effort to use.
3. Work Sharp Ken Onion – Best Knife Sharpening System
There’s a number of well-rounded knife sharpening systems out there, so this was harder to decide on. Even though it requires more effort and is costlier than some, we settled on the Work Sharp Ken Onion because no other can beat it in terms of both effectiveness and versatility.
- Creates razor-sharp edges
- Fixes, sharpens, and polishes
- 15 angle choices
- Multiple speed choices
- Takes a while to master
The Work Sharp Ken Onion is equally adept at fixing severely damaged knives and polishing fine edges to a mirror-like finish. And while some tasks may require more time, sharpening a dull kitchen knife to highly serviceable levels takes mere minutes.
The device offers more guided angle options than any other we know of. Choose any angle between 15 and 30 degrees at 1-degree increments. That should cover your whole knife collection, save for perhaps some specialty knives with actual razor-level grind angles. In fact, you can even sharpen those if you have a steady hand and the skills to work without the guides.
Even the sharpening speed is adjustable with the Ken Onion. It allows you to choose the proper RPM that’s most effective for every type of knife and knife material.
Of course, such versatility comes at a cost: The learning curve is steeper on this device than most. We suggest you page through the manual thoroughly beforehand and use your cheapest or least favorite knives in your first sharpening attempts.
We haven’t experienced blade scratches while sharpening with the Ken Onion like some other users have reported. However, we found that keeping the edge even is more an art than a science. For some reason, it’s very easy to end up with an edge that’s broader on one side than the other. This might be preventable if you pay close attention and keep the knife straight and parallel to the guide at all times.
Other than that, we can’t truly complain about the Work Sharp Ken Onion. As many users have admitted, you will become obsessed with sharpness and will start looking for more opportunities to use the tool. We surely have.
4. Sharp Pebble Premium – Best Sharpening Stone
The Sharp Pebble kit has all you need to get started with stone-style sharpening. It’s a modern take on the classic stone with two grit levels, an angle guide, and a guidebook for new learners.
- Set includes everything you need
- Balanced duo grit
- Ebook guide included
- Good customer service
- Hardness of guide is high and may scratch your knives
The Sharp Pebble whetstone sharpener comes with everything you need: the double stone itself, a beautiful base to stabilize it, and an angle guide.
The stone is a combination of two waterstones. The blue part, which has a grit or grain density of 1000, is for sharpening dull blades. The white side, meanwhile, has a 6000 grain density for finer honing and finishing. This is the perfect grit duo for newbies and experts alike.
It takes a little practice to master, but the simplicity and low cost of the Sharp Pebble make it one of the best options.
Remember that a 1000 grit whetstone is quite coarse, so you shouldn’t use it very often. Once every four to six months is sufficient. Honing with the fine side, however, can be done much more often.
The base is a solid, durable block of bamboo with a slip-resistant layer on the underside. Its upper silicone component grips the stone to give it extra stability. The silicone and bamboo are both easy to wipe clean.
The set, however, is not without flaws. While most customers find the guide rod useful, there are complaints that it leaves marks and scratches. You may want to try it out on your less expensive blades first, especially if you’re not already practiced with whetstones.
5. Smith’s PP1 Pocket – Best Pocket Knife Sharpener
Compact, affordable, yet multifunctional, the Pocket Pal from Smith’s is intended for use on pocket knives and outdoor tools. Think of this little foldable unit as the Swiss Army knife of knife sharpeners.
- Small, portable
- Tackles both straight and serrated blades
- Has fine honing option
- May feel awkward when held in larger hands
Small enough to fit into your pocket, the Pocket Pal sharpener has a diamond-coated rear rod that can fold neatly into its shell. Since the rod is tapered to a small point, it can slide between the teeth on your serrated knife, delivering a proper sharpening.
The Pocket Pal comes with two slots for quick sharpening. It has a coarse carbide slot for revitalizing dull edges, and a fine one made of ceramic for providing a smoother hone. This ceramic slot can work on both straight and serrated knives.
Thanks to its three sharpening options, the Pocket Pal can handle any type of pocket blade, from a brawny hunting knife to a straight-edged camping pocket knife. Theoretically, it can even tackle bulky swords and cleavers, though such large blades would take a lot of time.
The Pocket Pal is easy to carry around on fishing or camping trips, and with a concave grip it’s foolproof: You will know intuitively how and where to hold it properly. It’s small and may feel awkward if you have big hands, but that’s the price of portability.
6. Lansky Deluxe 5-Stone Sharpening – Best Manual Knife Sharpener
We picked the Lansky kit as the best manual knife sharpening system knowing it is not going to be everyone’s cup of tea. It takes time, but if you enjoy the process of giving your blades new razor-sharp edges, you will fall in love with this versatile tool.
- Easy (and fun) to use
- Does both sharpening and honing
- Works for various knife types and edge angles
- No guides for Asian blades
The kit comes in a neat box with, among other things, five stones of different grits and colors, making it look like a playkit. And itisfun to play with.
With guide rods and a knife clamp, it allows you to sharpen your knives to various angles with satisfying precision. It can handle any type of kitchen knife: chef’s, butcher, fillet, and even knives for hunting and outdoor uses. The small bottle of honing oil that comes in the package helps too.
With the smallest angle being 17 degrees, the guide rods won’t be so useful on Asian knives, which usually come with edges of 13 to 15 degrees. You can sharpen them without the rods, of course, but it takes more practice and a steady hand.
7. Utopia Kitchen 10 Inch Steel – Best Honing Steel
The Utopia wins our vote as the best honing steel to buy in 2021: It’s solid, does its job well, and comes at a reasonable price.
- Easy to use
- Effective in keeping knife edge
- Made of durable materials
- Not dishwasher safe
- Doesn’t really “sharpen” knives
The honing steel comes in two length options: 10 inches and 12 inches. Made of carbon steel and plated with a thick layer of nickel-chrome, it feels solid and properly weighted (11.4 ounces). It has a solid plastic handle with a “bolster” that balances out part of the weight of the metal, providing comfort during the honing process. This bolster also helps with safety, as it keeps your hand from slipping down while holding the rod in a vertical direction.
Note that while it’s sometimes called “sharpening steel,” the Utopia is really a honing tool—it doesn’t create new edges on your blade. You will still have to give your knives proper sharpening with more serious tools every six to 12 months. This rod’s purpose is to keep the edges keen between more major sharpenings.
The rod does well at what it is designed to do. It will straighten curled blade edges and remove little metal burrs, keeping the blade sharp and smooth. Give your blade a few strokes, and you won’t have any problem with tough chicken skin or ripe tomatoes.
A large ring at the end of the handle allows you to hang it on a rack or hook it on the wall. It’s a minor but much-appreciated feature, because you will need to hone your knivesoften—ideally before every use. Keeping it somewhere easy to reach would be a good idea.
Pro tip: After cleaning, season the rod with a touch of cooking oil to prevent rust.
8. WEN 4270 10-Inch Two-Direction – Best for Heavy Duty
Looking for a sharpener that works not only on kitchen knives, but also bulky garden tools? You may like the WEN 4270 sharpening system. It’s more of an industrial-grade tool with a versatile jig for various blade angles.
- Fast, effective sharpening
- Has jig for angle guide
- Single speed
This is a heavy-duty wet/dry sharpening system. It features a 10-inch stone wheel for coarse sharpening, plus an 8-inch leather-stropping wheel for polishing your blades.
You begin with the stone, using the jig and guide for the desired angle. Since the stone is highly abrasive (220 grit), you may want to start with cheaper axes, chisels, or damaged knives until you get the hang of it. Otherwise, you risk leaving ugly scratches on your expensive blades.
You may also want to follow it with a few dressing stones of lower coarseness levels. We recommend the finer 1000 grit and 6000 grit for thinner, smaller knives. Those more fragile knives will also do better if you sharpen them wet. The water can reduce the heat caused by friction and act as a lubricant to minimize damage to the edge.
After sharpening with the stone, your blade should be sharp enough to cut through paper. If you want to give it a final polish, move on to the stropping wheel. You can do it dry, but some sharpening oil for lubrication makes for slightly better results. Your blade will shine like a mirror after this step.
Weighing in at 36 pounds, the WEN is not an appliance you’d want to put on your kitchen countertop for casual sharpening. Rather, it’s designed for serious knife enthusiasts and outdoorsmen who need a strong and versatile sharpener to handle their knives and tools.
9. Smith’s DRET Diamond – Best for Serrated Blades
Serrations are difficult to sharpen, so serrated knives require a more specialized type of sharpener. Smith’s retractable DRET retractable sharpening pen is specifically designed for the job.
- Works on both straight and serrated knives
- Coarse abrasive diamond dust (400 grit)
- Not efficient for big knives
- Can be too coarse for thin edges
The sharpener comes in the shape and size of a pen with a retractable rod at one end. The tapered tip of this diamond-dust-coated rod can get to the smallest crevices between the teeth of your knife, returning them to their original sharpness. Being so compact in size, it can even sharpen gutting hooks.
The DRET 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 be a lifesaver. While the tapered part is for sharpening the teeth, the half-rounded end of the rod can take care of the straight part of the edge.
Sharpening a long blade will surely be time-consuming. However, when there’s serrations, 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 to secure it in your pocket.
Why It’s Worth Buying a Sharpener
Do you feel excited every time you try out anewkitchen knife?
Regardless of the brand or material, your new knife seems to always offer the perfect cut. Every motion you make with it is effortless. Precision is on-the-dot. Prepping your meals feels too fast because it is such a joy to use the knife!
With time and use, even the best knives will eventually become dull. You could cut the wrong thing and instantly chip or break the knife, but most of the time, dullness doesn’t happen overnight. It’s a gradual, almost imperceptible process.
The good news is, there are tools you can use to maintain the keenness of your knife’s edge and your delight in food prepping. Those are home sharpening devices.
A good sharpener will burnish, maintain, or fix the edge and prolong the lifespan of your knives. Simple devices like honing rods straighten and keep the edge keen for longer in between sharpenings. Advanced tools like whetstones, meanwhile, can fix severely damaged blades, rejuvenate the edge, and re-define edge angle, effectively keeping your beloved knives at the factory sharpness level.
The right sharpener will help maintain and repair your blades properly as soon as the need arises, all in the comfort and convenience of your own home. Take the time to learn how to use them so food prepping in the kitchen can always be fast, efficient, and enjoyable.
You may even end up finding yourself a new hobby in sharpening.
