How to Choose a Knife Sharpening Method
Each of the blade sharpening tools we’ll discuss here has its own pros and cons. In fact, each user is likely to find their own set of pros and cons with each method. There’s no right way for everyone. You want to look for the method that suits you best, whether it be a manual kitchen knife sharpener, a fully functional professional electric knife sharpener, or a sharpening stone. That said, some methods just produce a better result, thus we will focus on those methods.
Criteria for choosing the best home knife sharpener
- Type of sharpening mechanism: There are two key factors that you should look for in a manual or electric knife sharpener.
- First, the type of abrasive properties it has. Carbides can rough up the surface of your knifes and produce inconsistent results. Diamond, however, produces a strong, sharp blade. Sharpeners with diamond abrasive last longer and are of much higher quality.
- Second is the type of sharpening chamber it has. Some create a better grip on the knife which allows for consistent contact with the blade. Wobbly chambers
- Type of blades it sharpens: You’ll need to know your knives in order to determine the type of sharpener that’s best for you. Most techniques will easily sharpen straight-edge blades, but not all of them can handle angled knives, or 15-degree blades. Even less can handle serated edges or ceramic knives. After you see this extensive lesson on how to sharpen a serrated knife, you’ll probably want to find an electric knife sharpener that can sharpen serrated knives for you!
- Learning curve: With any new tool or appliance, there will be a learning curve. Whether it’s that you’ve never used that tool before, or that this particular model is more difficult than others you’ve used, those are all considerations to make when deciding on the right kitchen knife sharpener for you.
- Cleaning requirements: Each method has specific cleaning requirements, and some can certainly be more tedius and time consuming than others.
- Does it damage the blade: When I first started sharpening my knives, I worried a lot about damaging the blade. A good sharpener won’t damage the blade and I’ll go even further to say that it should guide well so that a user cannot cause damage inadvertantly when using it. Many sharpeners come with different possible blade angles to produce the correct type of edge on different knife styles
- Does it sharpen to your standards: Everyone has a different ideal for how sharp their knifes should be. I perfer to work with only the sharpest blades and I can easily tell when they are dulling. Some knife sharpeners acheive better results than others. If you want the sharpest blade, you’ll likely have to spend more to get it.
- Space constraints: This is pretty self evident, but if you don’t have a lot of space in your kitchen for extra appliances, a small manual knife sharpener takes up much less space than an electric one does. Along the same lines, a professional electric sharpener will likely take up the most space.
- Noise: There are a good many cheap knife sharpeners AND expensive ones that make a horrible amount of noise. The amount of noise they make doesn’t necessary relate to how well they’re sharpening, but it might sway you in another direction.
Types of Knife Sharpeners
Manual knife sharpeners
Manual sharpeners are generally very easy to learn how to use and they allow for a great degree of control when sharpening your knifes. They also take up considerably less amount of space in your kitchen and don’t produce any loud, obnoxious noises. To use a manual knife sharpener, you pull the blade of your knife through the slot provided and work the blade back and forth along the … Manual sharpeners are generally quite a bit less expensive than electric sharpeners, they are lighter weight, smaller, and can be just as good at producing a sharp edge, when you apply the right pressure.
Electric knife sharpeners
An electric knife sharpener takes the manual labor out of sharpening a knife. Some think they can cause damage to your knives and can do no better in sharpening than using a good old fashioned stone, thus they aren’t a good idea, but if you choose the right electric knife sharpener, they can be a really great helper to many people how don’t want to learn how to use a stone, or just want to simplify the process. Electric knife sharpeners are larger than manual ones and they require the use of electricity, so they aren’t as portable either. But they do the work for you, thus requiring less precision and input on your part.
Wet Stone knife sharpeners
Some kitchen gurus swear by water stones for sharpening, saying they deliver very high quality sharpness, but using them takes a lot of practice and patience, until you’ve mastered the skill. I’ve never really gotten the hang of a wet stone sharpener, and I never really wanted to spend the time learning it properly. That makes me, and many other home cooks, not the perfect candidate for wet stone sharpening. However, if you have the patience and are willing to develop the skill required, it can be very effective and it won’t require buying a really expensive electric machine that itself requires maintenance and could breakdown.
Sharpening and honing rods
We’ve included the honing rod in our reviews because it is an integral part of keeping your knives sharp and the edge straight to enable ease of use in the kitchen. Honing your knives is different from sharpening them. A honing rod should be used in between sharpenings to keep the edge upright and cutting well. If you bought a knife set, it’s likely that it came with a steel honing rod. And it’s also likely that you have been under the impression that this tool is used for sharpening your knives, but it isn’t. Rods are meant to correct the shape of the edge of the blade. Over time, the knife’s edge can roll over, causing it to cut as if the blade is no longer sharp. Rather than needing to be sharpened again, the knife just needs to be honed, to return the edge to its perfectly aligned position. It is for this reason that a honing rod should be used on your knives more frequently than a sharpener.
Top Knife Sharpener Questions Asked
It’s always wise to be fully prepared to make your decision, and getting your questions answered is part of that equation. Below you will find a few of the top questions and answers that are often asked about knife sharpeners. If you’d like to read more, check out our post with the top 10 knife sharpening questions.
Question: Why do I need a knife sharpener?
Answer: When you first buy a knife, it’s got a perfect angle and sharpness that makes cutting and chopping easy and safe. But over time the blade can begin to bend, chip and become dull. If you don’t regularly hone your knives after use, the edge will become very dull and will no longer cut easily through foods, as it once did. Keeping your knives sharp is important for a number of reasons, the most important of which are to make cutting as easy and fluid as possible, and to prevent accidents caused by dull blades. You can keep a knife in tip top shape for quite some time by regularly using a honing rod on it after every few uses. But eventually you will need to sharpen the knife again. You can have this professionally done, or you can do it yourself at home.
Question: Are counter top knife sharpeners actually good for sharpening knives?
Answer: There are many different types of knife sharpeners, both electric and manual, so it’s not easy to make a sweeping assumption about all counter top knife sharpeners. There are some that are better than others. Knife sharpeners that are made with the best quality products, and use diamond abrasives are the best and can sharpen your knives fairly well, without removing too much metal. On the other hand, lesser-quality sharpeners can cause significant damage to your knives, and many remove a lot of metal which can more quickly deteriorate the use of the knife. Would I use just any counter top sharpener on my most expensive knives? Absolutely not. But if you have a drawer full of basic kitchen knives, you can certainly sharpen them well with the right sharpener. These type of sharpeners can be a really great helper to many people how don’t want to learn how to use a stone, or just want to simplify the process.
Question: Can a knife sharpener damage my knives?
Answer: Yes, it is possible for a knife sharpener to damage your knives. This happens most frequently because the sharpener used was of low quality and the abrasives actually strip away too much metal, or are not aligned properly, thus making the edge even more dull in the process. User error is also to blame in many cases. If you are not sure how to operate the knife sharpener, you can damage the blade by running it through the abrasives too many times, with too much pressure, or at a slight angle. It is imperative to buy a high-quality knife sharpener and to fully understand how to use it before attempting to sharpen a knife.
Question: How often do I need to sharpen my knives?
Answer: Regular honing of your knives is the most important step in keeping your blades up to par. If you hone your knives after every heavy use, or every 2-3 regular uses, it will stay sharp for a very long time. If you are disciplined about this, you may not need to fully sharpen your knives very often, if ever. However, if your dedication falls slack, you may need to sharpen and polish your knife once every 6-8 months. If you never do any honing and are tough on your knives (drop them into the sink, put them in the dish washer, cut through things they shouldn’t be used for, etc) you may need to sharpen ever 3 months. This way of treating your knives will result in the shortest life-span for the knife.
Question: Can a knife sharpener be used on ceramic knifes?
Answer: Generally, the answer is no. While there are some knife sharpeners that do sharpen ceramic knives, the vast majority do not. You must be very careful to select the correct one.
Question: Can a knife sharpener be used on all knives?
Answer: Much like the previous answer, the type of knife you can sharpen with a specific sharpener varies greatly. You need to be aware of the types of knives that can be used with a specific sharpener. Some have slots for fishing and hunting knives, pocket knives, all types of kitchen knives, and even scissors. Some only allow for a specific type of metal and/or bevel angle.
Question: How long does it take to sharpen a knife with a sharpener? How many times do I pull the knife through the slot?
Answer: This answer varies based on how damaged the knife is. If you have a rather heavily damaged knife, you may need to pull it through the course slot 6-8 times, then through the fine slot another 6 times and finally through the polishing slot another 3 times. This will take about 8 minutes to complete. If the knife you’re sharpening is not damaged, just a bit dull, you’d only pull it through the fine slot 3-4 times, and through the polishing slot 3 times. You never want to apply heavy pressure when pull the knife through the slot.

Best Electric Knife Sharpener Reviews
*Best for budget electric knife sharpening
EverSharp Electric Knife Sharpener
The Presto 08800 is a basic, entry-level electric knife sharpener. If you’re new to the world of knife sharpening and looking to give new life to your dull knives, it will do the trick, but don’t expect a perfect edge every time. The Presto uses Sapphirite abrasives to sharpen in the first stage. It then has a second stage for honing. It is designed for standard kitchen knives made of alloy, carbon, or stainless steel, but does not work with Japanese or 15-degree angle knives. And it can sharpen one-edged serrated knives.
With the Presto, there’s no guess work. The blade guides lead the knife through each stage to produce the right angle. It will only take a few passes through stage one to achieve a fairly good result, and you may even find that passing it through too many times or using too much pressure can result in a duller result. The honing process is necessary to smooth the final edge.
Though it won’t be as razor sharp as with some diamond-abrasive machines, the edge achieved with the Presto 08800 is decent for the price of this electric knife sharpener. If you’re looking for a higher-quality product, the 08810 professional-grade adds an additional stage to the process for fixing up even the dullest or nicked up knives.

Best Sharpener Rod Reviews
Messermeister 10″ Ceramic Rod / Sharpening Steel
This Messermeister is made of ceramic which is very smooth. A ceramic rod should be used with most Asian knives that have more delicate blades and thinner edges. The ceramic rod provides a nice smooth finish on the knife’s knewly sharpened edge.
Although this particular ceramic sharpener is a 10″ rod, other sizes (including a 8″ and a 12″) are also available. You should purchase a rod that is about the same length or slightly longer than the knives you’ll be using to sharpen it with. This Messermeister rod had an argonimical grip and comes with a lifetime manufacturing warranty. Just be sure not to drop it, because the ceramic could shatter.
Wüsthof – 10″ Knife Sharpening Steel with Loop
Most of the sharpening rods that come with knife block sets are steel honing rods with grooves. In most cases, it is preferable to use a smoother steel rod, so it doesn’t scuff up the sharp edge too much. This Wüsthof sharpening steel is made from chromium plated steel with a hardness of 65° Rockwell has a fairly smooth surface so you don’t have to worry much about wearing down the blade. This 10″ steel rod is best used with knives that you’ll be using for tougher foods, like thick-skinned produce and meat, because of the micro-scuffing that will be added by the steel. It has a slip-resistant plastic handle and loop on the end so you can hang it on a hook in the kitchen.
