Sharp kitchen knives are a must-have tool for any home chef. From chopping vegetables to fileting fish and poultry, sharp and effective kitchen knives can save you time during meal prep. To help keep your knives sharp and effective, regularly sharpen them with a knife sharpening system.

Knife sharpening systems are tools that grind blades against a rough hard surface to polish and smooth out their edges. Knife sharpeners can be manual or electric and usually use stone or diamond to help sharpen knife edges, ensuring a razor-sharp cut even after many uses.

Corey Milligan, founder of New West KnifeWorks, says the first thing to know about knife sharpening is that it's going to come with a learning curve, regardless of what type of system you choose. “The truth is, the best sharpener is you,” he says. “So, you need to find a system that not only works well, but one that you can actually see yourself enjoying to use.”

To help narrow down the best knife sharpening systems on the market today, we researched the category, looking at things like material, precision, ease of use, and price accessibility.

Here are our recommendations for the best knife sharpening systems.

This system works incredibly fast, about one minute for a first time sharpening and about 10 seconds for resharpening.

It’s pricier than most other options on this list, but well worth the investment.

The Chef’s Choice Trizor 5XV electric knife sharpener will turn your standard kitchen knives into high performance tools with Trizor XV 15-degree edges, thanks to a highly effective three-step process.

The first and second stages use pure diamond abrasives to file and sharpen knife edges, while stage three uses a flexible abrasive system to polish and strengthen, helping prolong the lifespan of both straight-edge and serrated blades. A flexible spring system automatically adjusts the knife’s angle to help you keep greater control during the process.

We love that this knife sharpening system is both fast and very easy to use. You can complete a first-time sharpening in approximately one minute, while resharpening takes about 10 seconds. To operate, simply use the on/off switch and move your knife through the three different facets, which are specifically set at different angles for more precise accuracy.

Measuring just 10 inches wide and weighing about 4 pounds, it can be comfortably used on any kitchen countertop, and easily stored in any kitchen cabinet. You also get the peace of mind of a three-year limited warranty.

The Chef’s Choice Trizor 5XV isn’t the most inexpensive pick on our list, but the performance, user-friendliness and conveniently compact size make this knife sharpening system well worth the investment.

It has a nonslip base and an ergonomic handle.

It may not last as long as other options on our list.

If you are new to knife sharpening or looking for a much less expensive option, this pick by PriorityChef is the best knife sharpening system. This tool features a two-stage manual sharpener that is designed specifically for keeping straight edge knives looking razor sharp.

In the first slot, you’ll find a diamond-coated wheel in the first slot that will help file the edge of your knife’s blade. To use, simply pull the knife through about 10 times. The second slot will polish your knife with the help of a ceramic honing wheel. Like with step one, you simply pull your knife through about 10 times for best results.

Besides being easy to use, this knife sharpener is constructed of durable stainless steel and boasts a sleek minimalist design, which makes it easy to fit into any kitchen aesthetic. This knife sharpener also features a no-slip base to help keep your device stationary while you are sharpening your knives. It also has an ergonomic handle that provides better control and makes the sharpener easy to grip.

Because of its low price, it may not last as long as other knife sharpening systems on our list. However, since it’s easy to use and affordable, this is the best knife sharpening system for those who are looking for a budget-friendly option.

This is a versatile system capable of sharpening even ultra-fine knives and cleavers.

It only comes with a 20-degree sharpening module.

Any collection of high-end knives is worthy of a knife sharpening system that's equally high end. So, if you’re looking to invest a bit, the best knife sharpening system is this pick by Chef’s Choice. This commercial-grade tool features a 3-stage sharpener with patented Edge Select technology that lets you choose an edge to match your specific cutting task. Diamond abrasive discs and a super fine file result in razor sharp edges.

Measuring about 12.5 inches long and just under 5 pounds, this is a surprisingly lightweight electric knife sharpening system that won’t take up too much space in your kitchen.

This knife sharpening system comes with an easily removable 20-degree class module that will work for most straight-edge and serrated American and European kitchen knives. We love that you can also swap this module out for a 15-degree or ceramic knife sharpening module, which makes it the most versatile option on our list.

However, the latter modules must be purchased separately. If you are looking for a system that can tackle ceramic and ultra-fine knives, this pick is worth the investment. However, if you mostly have standard kitchen knives, you might want to consider a more budget-friendly option with a 15-degree module.

This one-step system uses the centuries-old technique of leather stropping to effectively sharpen and polish even the dullest knives.

The 14-degree angle sharpening works best for small and medium knives like steak knives and paring knives.

The German brand Wüshtof has been around since the 1800s and has earned a reputation for producing high quality knives. So, it comes as no surprise that the brand would also offer a highly effective knife sharpening system for keeping your kitchen blades in top form.

Unlike other systems that use diamond abrasive discs or coarse sharpening steels, the Easy Edge Electric Sharpener uses a leather belt that relies on friction to help file the blade of any dull knife.

A manual knife sharpening practice that’s been used for centuries, leather stropping goes a step further than just polishing your knives — there are microscopic fibers in the leather that can actually grab on to the metal of the blade to realign it. This results in a sharper, smoother blade.

The one-step system is easy to use. Simply put your knife into the sharpening slit and let the machine work its magic. There are three sharpening stages to ensure a smooth, razor-sharp finish, a convenient interchangeable angle guide, and integrated dust suction to minimize mess.

Keep in mind that the 14-degree angle sharpening works best for small and medium knives. Use it with your favorite paring and slicing knives for best results.

With no electric outlet needed, you can use this lightweight and portable knife sharpener just about anywhere.

This sharpener was designed for standard knives and won't work on filet knives or ultra-fine cleavers.

Manual knife sharpeners are convenient in that they don’t rely on an electrical outlet to function. We chose this pick by Chef’s Choice as the best manual knife sharpening system because it features a three-stage manual sharpener that uses diamond abrasive discs at each stage to form an angle on each side of the blade, which helps keep it sharp considerably longer. It also sharpens the entire length of the blade, which makes for more effective slicing, dicing, and chopping.

Because this knife sharpener doesn’t need to be plugged into an outlet, you can use it just about anywhere, which makes it a handy tool for RVs or campers. We also love that this manual knife sharpener is easy to use and designed to operate either right- or left-handed. It also comes with a slip-resistant base that prevents your sharpener from sliding across the countertop while in use.

Keep in mind that this knife sharpener was designed to fit both straight edge or serrated knives of 15- or 20-degree class, which covers most standard American and European knives.

However, if you have other more fine or delicate knives such as fish filet blades or cleavers, you will want to look for something designed for a higher degree class (25- to 30-degree) depending on your specific knives.

Special precision blades minimize guesswork by guiding the positioning of your knives to ensure perfect results.

You can’t run double-serrated blades through this sharpener.

A knife sharpening system can be an intimidating purchase for the novice home cook. And while electric knife sharpeners are typically faster and easier to use than other manual options, some models still require a learning curve. If you’re looking for something that’s extremely user-friendly, this pick from Presto is a great option.

We chose this as the best entry level knife sharpener for several reasons. It has a two-step system versus a three-step system seen on other models. It uses convenient precision blade guides that hold your knife at the perfect angle, minimizing any guesswork. It also works extremely fast, creating an acute edge in seconds thanks to its Saphrite sharpening wheels—the same material used by professionals.

We also appreciate the ergonomic design and suction cups on the bottom of the base, which holds your knife sharpener in place, minimizing accidental slips.

Keep in mind that while this tool works exceptionally well for most American and European straight edge knives, it won’t work for double serrated blades like those found on bread knives. But for the price, this knife sharpening system is definitely worth it.

Unlike other sharpening stones, this one doesn’t need to be soaked in water before use.

Because this is a manual sharpening stone, it will require more patience than using an electric option.

A high-quality sharpening stone like this pick from Naniwa is extremely effective at helping return knife blades to razor sharpness. It does this by quickly removing substantial amounts of blade, easily grinding away at chips or even setting a new bevel angle on your knives.

This sharpening stone is made of 3,000 grit sharpening synthetic water stone that offers strong hardness and polishing effects. Unlike other sharpening stones, you don’t have to soak this one in water before each use. Just add a light splash of water and it is ready to go.

While it does require a bit more patience than sliding your knives through an electric sharpener, the Chosera 3000 is a great option for fine, delicate knives. Diamond stone systems, while quick to sharpen, are aggressive and can leave small marks on your blade. The Chosera 3000 will quickly remove metal from your blade, leaving a nice smooth edge without compromising the rest of the material.

Make sure to follow care instructions with this option—if not cared for properly, this stone can crack after prolonged use. Make sure you follow proper maintenance to get the most out of your sharpening stone.

Small enough to fit in your pocket, this is a perfect knife sharpener to use on the go.

You’ll want to be careful how you position your fingers to avoid an injury.

If you’re looking for the best knife sharpening system for travel, a quick-fix sharpener like the Lansky D-Sharp is a great option. Lightweight and compact, this sharpener provides a super fast blade tune up without the need for larger equipment, making it a perfect solution for taking with you on fishing or camping trips.

It uses diamond to effectively file your knife edges, as well as a ceramic bench stone that will polish both straight and serrated blades, leaving them looking new again. Because you can choose from four different sharpening angles, this knife sharpener is especially handy at handling a variety of cooking tasks.

The 17-, 20-, and 25-degree angles can sharpen blades for everyday cubing, cutting, and peeling, while the 30-degree is perfect for those delicate knives used for slicing and mincing.

As the name suggests, this is a quick fix sharpening system and won’t effectively replace a more complete knife sharpening system in the long run. You’ll also want to be careful how you position your fingers during use to avoid an injury. If you are new to knife sharpening, you might want to consider a different option.

This sharpener is lightweight and easy to store.

It’s intended as a maintenance tool and won’t work well on very worn blades.

When it comes to the best knife sharpening systems, a ceramic tool like this pick from Bob Kramer by Zwilling is both effective wear-resistant, making it a great option for those who plan on using their knife sharpeners very often.

This 10-inch rod is constructed from Japanese-made honing steel that will sharpen knives much faster than systems that file using diamond or other material. You’ll be able to see the difference in just a few careful pulls.

This ceramic sharpening rod also has a sturdy plastic handle that’s comfortable to use. We also like that it requires just one step—a few swipes on the blade—versus other multi-step sharpening systems, which could take up to 10 minutes with each use. This means you’ll spend less time sharpening.

It’s worth noting that this sharpening rod is ideal for use on straight carbon steel blades. If you have knives made of semi-stainless steel, cobalt, titanium alloy or ceramic, you might want to look into other options.

It’s also intended to be a maintenance tool, which means it’s most effective when used on knives that are still sharp. If you have dull knives that require extensive sharpening, you might want to look into a more complete sharpening system.

We chose the Chef’s Choice Trizor 5XV electric knife sharpener as our best overall pick because of incredibly effective 100% diamond abrasiveness that makes it possible to sharpen your knives in just 10 seconds. We also like that it’s compact—weighing just 4 pounds—which makes moving it from the kitchen cabinet to countertop a breeze.

The best knife sharpening systems are available in a wide range of sizes to fit your needs. Countertop options can measure about 12 inches wide and 5 inches tall, making them easy to keep nearby for a quick knife sharpening without compromising too much kitchen space.

Knife sharpening stones or sharpening rods can easily fit into a standard drawer, while quick fix knife sharpeners can be small enough to carry in your pocket.

When shopping for the best knife sharpening systems, you’ll need to choose between an electric or manual system. Both these options typically use diamond abrasive discs to sharpen knives. Some also feature ceramic for polishing.

Other types of manual knife sharpening tools include leather strops, ceramic rods and sharpening stones. Each of these use their specific material to break down excess steel on your knives, resulting in a smooth and razor-sharp finish.

The best knife sharpening systems typically range from 15- to 30-degree angles. This simply means at what degree they polish the knife’s edge.

For most standard kitchen knives, a 15- to 20-degree angle is most effective. However, for finer edge knives like certain cleavers or those used for filleting, you’ll want to look for something with a 25- or 30-angle precision.

When shopping for the best knife sharpening systems, you’ll find options that require different skill levels. Electric sharpening systems are typically the most beginner friendly, with many options even capable of automatically adjusting knife placement to keep accurate control over the sharpening angle.

Manual knife sharpening systems, especially rods and sharpening stones, require more of a learning curve, primarily to ensure you’re sharpening at the most ideal angle. However, if you like more control over your knife sharpening and are excited at the idea of perfecting your knife skills over time, a manual knife sharpening system could be right for you.

“It’s a really subjective thing,” Milligan says. “Some people prefer it to be like an art, others like a science—and different systems are designed for both of those types of people.”

“There are many types of sharpeners that are effective,” Milligan says. “Stones, ceramic rods, gadgets.” Unless the product specifies, you’ll want to avoid an electric or manual knife sharpening system because it can damage the blades.

To find the best knife sharpening system for you, make sure the device can accommodate sharpening your knives at the angle needed. 15-20 degree angles are standard for most kitchen knives. Narrower angles are best used for sharp knives, like paring knives, while wider angles (between 30 and 35 degrees) are used for cleavers.

“Most important is to get one that is highly recommended and that includes videos that show you how to use it,” Milligan says. “Then learn how to be an expert of the sharpener you have. Practice and stay with it.”

There are several factors that affect a knife’s overall sharpness and how long that sharpness lasts. This includes the knife’s material, what you’re using the knife for, and how well you’re caring for it.

As a rule of thumb, a good stainless steel knife should stay sharp from 6-12 months, but could last up to two years with proper care and maintenance. Regular sharpening will ensure the longevity of your knives. You’ll also want to avoid using your knives on material that can be damaging to the steel, such as ceramic, glass, granite, and marble.

According to Milligan, it all depends on how much you use them. “For a professional, working all day on the line, it could be daily,” he says. “For home use, weekly or monthly if your aim is to keep them really sharp.”
