A Little Background

At a glance, knife sharpening is one of the most commonly used techniques in the industry, especially when it comes to manual work that involves accuracy. Knives are not limited to kitchen use, but in most cases, but also applies to heavier work such as gardening and many other fields.

Back in the old days, sharpening knives was only doable through the work of a shop owner or tool smith due to the unavailability of portable knife sharpeners and limited technology of the past. But today, we should thank these manufacturers and designers for innovating solutions on safer, easier, cheaper and more convenient ways to sharpen our old, dull knives and similar bladed tools.
The grinding stone, diamond, ceramic or any material used for honing blades affect the quality and sharpness of any knife or tool. Some kitchen knives also require specific angles to be honed and thus, cannot be simply sharpened using regular sharpeners.

Different knives and tools call for different methods of sharpening, but generally there are three processes or stages. The first one to sharpen the blade by means of sharpening tools, both traditional and modern, to remove excess metal and keep the old and dull blade sharpened again. Some blades may be straightened if needed due to deformity and this does not require removing metal. Polishing or stropping is the finishing touch for any blade material to make it look shiny brand new.

Proper blade usage and maintenance is very important if you want to keep your tools as sharp as possible. For instance, don’t use thinner blades for heavy duty cutting. For instance, chopping hard meat and similar food items requires thicker blades and you shouldn’t use your fillet knives and such so that they don’t get dull too easily.

Cleaning after use is also very important, as it also lengthens the life span of the blade’s sharpness. Cutting boards must also be chosen carefully to avoid potential dulling of the knife you are using.

Don’t be afraid to invest in different kinds of knives – this is why they are all manufactured differently for various specific purposes, so that they don’t exhaust their sharpness quickly. And if possible, pick a knife brand that you are aware of the quality and don’t just go for something cheap when you know it easily gets dull even with proper handling.

It is important that before you go for a knife sharpener, you have already gone through years of proper care for your knives and tools, so that your knife sharpener will also do the job easier for you.

How We Picked

Choosing the best knife sharpener isn’t really a walk in the park. We chose considering different criteria for picking our best recommended products.

The sharpener must have a user-friendly approach, meaning that it will cater to all people in different levels and experiences on sharpening knives. In this way, people who are fairly new to the world of knife sharpening will not have a lot of problems starting out with their first, and at the same time, it must be a sharpener that is still tolerable and useful by advanced users.

Portability is also a big factor for choosing the best knife sharpener out there – unless you want something that only stays in the kitchen to impress the guests. But generally speaking, a knife sharpener that you can be able to bring out on camping trips, trekking adventures and venturing into the wild is something definitely awesome to look forward to.

Our Pick

SunrisePro Knife Sharpener
is our top contender and Jen’s top pick for the best knife sharpener.

Going back on our criteria with picking the best out there, this sharpener has a very balanced score when it comes to all of the said factors. This makes the SunrisePro a truly remarkable innovation when it comes to modern knife sharpening.
The suction pad keeps any user safe from getting nasty cuts because it keeps the whole thing in place as firm as possible. If your biggest concern is blade sharpening safety then you are in good luck with the SunrisePro.

Aside from its stability, it can perform sharpening on a variety of tools and not just kitchen knives! Whether you are just a casual person working on the kitchen or someone who needs to badly sharpen his or her set of tools, you got the right sharpener for the job. You can work with tons of blade sizes, whether they’re from highly expensive stores or just cheap but efficient ones, and still get the same quality results with just 3 to 4 swipes on the sharpener. It even works on blender blades and even serrated blades – something that most common knife sharpeners in the market don’t always have.

The fact that it is designed to be portable allows you take it to picnic and camping grounds. The attractive color finish also makes it an eye-candy, whether on the kitchen counter or outside your home. Compared to most knife sharpeners, this one doesn’t waste precious metal from your blade to make it sharp again and only chops off itty bitty amounts.

Who Else Likes It?

If your grandma or grandpa owns a lot of kitchen knives or similar tools but are afraid that they might get injured from unsafe sharpeners then you might want to give this to them as a gift for their personal use. They will definitely thank you for giving them a very user-friendly knife sharpener that stays where it should and sharpens blades in only about 1 minute or so.

People who are fairly new to sharpening knives and don’t want the hassle to go to a tool smith will also benefit from this product because of its easy-to-use functionality and design as well as portability. It is well worth spending for the price, especially for those who do not want to spend more bucks on expensive kitchen equipment or even on a new set of knives.

Flaws but Not Dealbrakers

Remember that even the best products out there have a few drawbacks, but should not worry you that much. In the case of the SunrisePro Knife Sharpener, its one known drawback is the slight inefficiency for super fine serrated knives, which means it might not cater to those who want to fine hone their serrated blades. However, this doesn’t necessarily mean it won’t work on serrated ones – it’s just not that suited for extremely fine ones.

Compared to more expensive products out there, it is also just a one-slot and one-process knife sharpener, whereas our other picks that are pricier have about 2 to 3 stages of sharpening for those who want to step up the game and want to spend extra for fine and meticulous sharpening.

Step-up Pick

Of course, not every person who needs to sharpen knives wants just the basics. Some advanced users, such as big-time restaurant chefs, will require something that will adhere to their cooking and preparation standards.

This is where the Chef’s Choice 15 Trizor XV EdgeSelect Electric Knife Sharpener
comes in handy. It comes in a pretty hefty price due to its Trizor edge sharpening feature and 3 step functionality.

Stropping disks and diamond abrasives make this sharpener all too special, but worth buying if you want total finesse in your blades. Ideally, if finely-detailed knife sharpening is what you’re looking for, and especially if you are working with a multitude of knives for a variety of cuisines, don’t hesitate to invest for this on your restaurant, because you’ll need it.

Another thing that adds to the price is the fact that it’s electric and more suited for industrial and restaurant management needs, where you have to meet tight schedules to not disappoint customers who are waiting for their orders. Sharper knives mean quicker work. Stropping is also part of the game and food presentation, especially if you work on a 5-star restaurant where guests can be too meticulous about the tools you use. Even if it’s sharp, without the shiny finishing it might turn off your spectators.

Contrary to the top pick, this Trizor specialized knife sharpener isn’t manual and it can also work on finely serrated blades and multiple knives at the same time to save you more time on the go. But of course, it’s a step-up product and that means more bucks to spend.

Budget Pick

The Lansky PS-MED01 BladeMedic
is a pocket-sized knife sharpener that will greatly satisfy you with its functionality, foldability and portability if you are a little low on the dough. Being Swiss knife style sharpener, you can choose from different sharpening options such as diamond tapered, serrated and ceramic, depending on what blade you own.

The fact that it is a pocket blade sharpener means that you can easily take it to camp and use it on your cooking, hunting or utility knives with ease. Versatility in a small package makes this a great and affordable knife sharpener, despite not having a sleek appearance due to the fact that it’s for outdoor use. It might also feel a little heavy to carry around, but that’s because it is heavy duty as a knife sharpener, made with great sharpening materials.

Much like our top pick, it works well with serrated knives and blades and makes use of tungsten carbide at only 3 to 4 swipes. So if you are in it for a bargain knife sharpener and you are not too particular with super fine quality sharpness and just want to sharpen a couple of old and dull blades to be able to use them again, don’t hesitate to buy this awesome knife sharpener.

Great for Thin Kitchen Knives


Designed to work with you specifically in the kitchen for sharpening your handy-dandy knives, the Rada Cutlery Quick Edge Knife Sharpener uses two stainless steel wheels to finely sharpen any thin kitchen knife and comes with a whopping lifetime guarantee. If you’re so much more into thin blades and cutlery, especially if you own a Rada knife (or any similar knife), this is the knife sharpener for you. However, as the description implies, it’s not suitable for big, butcher knives with thick sizes.

Multi-Angle, Foldable and Portable

If you’re into experimenting various angles when it comes to manual sharpening but absolutely need to take it outside during camping or hiking, the Goodia 400/600 Grit Knife Sharpener is an ideal butterfly knife style knife sharpener you would want to own. It features 400 Grit and 600 Grit for either coarse or finer sharpening respectively. Because of its double sided and foldable design, it is indeed a very convenient buddy to take with you out in the woods, and can sharpen most general blades such as kitchen knives, gardening tools, etc.

Hardwood Base Manual Sharpener


Aimed at those who want a manual sharpener made from hardwood and rods, the Lansky 4-rod Turn Box Crock Stick Sharpener does the job well using its two ceramic rods and even has rod storage on its bottom part. Coming with a 1 year warranty, its portable design also allows you to store it easily unlike a lot of larger sharpeners. It allows for 20 and 25 degree edge sharpening – good for manually honing fillet knives and other kitchen cutlery.

All-Around Motorized Tool Sharpener


Knives don’t just apply to kitchen knives, but also to a couple of other tools in gardening, utility, scissors, and many others. The heavy duty motor-powered Work Sharp WSKTS-KO Knife and Tool Sharpener Ken Onion Edition is a sure-fire recommendation for those who like to get sharpening work fast in multiple angles and want to maintain their industry-standard tools with extra precision sharpening. So if you own a multitude of small garden shovels other than knives then this is the equipment you’ll love to have. Its adjustable speed for its industry-compliant abrasive belts complements its multiple angle features.

Sleek Manual Sharpener


Do you want a knife sharpener that adheres very well to both straight and serrated knives? The PriorityChef Knife Sharpener for Straight and Serrated Knives uses a two-stage sharpening method (fine and coarse) and because of its sleek chrome finish design, it’s an eye-catching piece of functional kitchen equipment that will surely wow your guests. However, take note that this manual sharpener is best suited for advanced and intermediate users, so one who is fairly new to the process must take extreme caution.

Affordable and Electric


If you absolutely don’t want a manual sharpener due to the big fear of getting nasty papercuts then we greatly suggest the LINKYO Electric Knife Sharpener for a well-guided, two stage sharpening method that is easy to use and sticks to the ground with suction cups. It works fine for most kitchen knives and even other utility knives, as expected. The product is under lifetime warranty, but is slightly pricier and larger than our top pick. It may not work for serrated blades and scissors, though.

Good for Ceramic Knives and Steel Ones

Not all usual sharpeners for knives out there are effective towards ceramic knives, so most advanced users look for something specific such as this.


Another great 3 stage knife sharpener is the Knife Sharpener Easy Manual Professional 3-Stage Ceramic Knife Sharpening system if you are specifically looking for something to be able to put your old ceramic knives to good use. It also works well for most steel knives and its easy handling design keeps it comfortable to use and the multiple sections allow for a variety of tool and knife sizes to be sharpened easily.

The Competition

A lot of other brands on Amazon, with ratings 4.4 and below, range from super duper cheap price to surprisingly expensive ones – these were handpicked based on the ratio of rating, user reviews, ranking, uniqueness and functionality.

There are a variety of knife sharpeners out there, ranging from manual ones (that might hurt your fingers but help you become more exact and precise gaining control over your knife sharpening process and take more of your time) to electric or battery-operated ones (that require power, a lot of space and a bigger budget but does the job for you quicker than manual sharpening). There are also a couple of traditional tools such as sharpening stones, sharpening steels and many others, but since we are talking about the best ones with functionality and ease of use, these old school tools are more for the completely advanced users and not for the person who is fairly new to knives.

Some other knife sharpeners that didn’t make it to the list also lack design functionality and more specifically, user safety. But hey, isn’t blade sharpening already a dangerous task to do? Nonetheless, we are looking for something that lessens the threat of bleeding fingers or similar injuries while keeping a dull blade sharp again like it’s been newly purchased.

Other Frequently Asked Questions

Q: What happens if I don’t sharpen my dull knife or set of knives?
A: Dull knives, especially if used for chopping or cutting anything tough, might spring back and cause unwanted injuries, thereby labeling them unsafe to use. While it is okay if you are cutting soft food such as cheese or bread, heavy duty blades used for meat and other utility purposes must be finely sharpened to avoid such worst case scenarios to happen in the kitchen, in the shed, in the garden, or even outdoors at camp.

Q: What is the difference between a serrated blade and a straight blade?
A: Simply put, a serrated blade is one with teeth. You will find it mostly on saws and a couple of kitchen knives such as bread knives. Straight blades are the usual cutting knives that have a straight blade edge.

Q: What is stropping and is it needed after sharpening the knife?
A: Stropping is another word for polishing the knife to make it sparkle like brand new. While it is not a requirement to make your blade sharp again, in some cases it will enhance and rejuvenate the knife’s attractiveness, kind of like stem cell therapy on humans. Most chefs in restaurants always get their knives stropped for making them look more presentable even if they’re many years old.

Q: I’m new to sharpening knives and I’m afraid to get papercuts. Any advice?
A: Get help from elders or anyone you know who might have some knowledge of sharpening knives. Do it carefully and always keep your eye on the job. You may also learn a few tips and tricks on video sites like YouTube for proper knife sharpener tactics.

Q: Can I use any of these knife sharpeners for almost any knife or bladed tool?
A: Read the product’s details or user warnings first. Does it say it works okay for both serrated and straight knives? Will it be functional for both thin and thick, heavy duty knives or only one of them? Can scissors, gardening tools and other blades be used for it or is it just suitable for kitchen cutlery? It may be good to know these things first before you proceed and give a bad rating to the product that it didn’t deserve, just because you weren’t reading the warnings.

Q: Any more tips on how to strengthen and lengthen the life span of my knives?
A: According to a comprehensive guide by KnifeCenter, there are a variety of ways you can protect your knives from potential damage. For instance, even stainless steel can rust when under really bad storage conditions, so it’s a good idea to clean it thoroughly, dip it in special lubricants (especially for folding knives) and store in a place with less moisture and humidity. And of course, sharpening is one of these proper care tips that you should do on your knife.

Wrapping It Up

We like our top pick SunrisePro Knife Sharpener as it is an all-round outstanding knife sharpener. The ultimate best knife sharpener you pick will depend on whoever will sharpen the knives and what kind of knives will need some honing. It’s all a different ball game to different people, whether you work on your home kitchen or out there in a 5-star restaurant, so always choose depending on your budget, specific needs, and of course, knives you own.
