Did you know that a sharp knife is actually safer than a dull knife? While this guide is not being presented to you to go in depth about this factoid, it really sets up why you are here today. You see, even the best knives are going to dull over time and the more you use them, the quicker this will happen. And, when they get to the point where they can’t efficiently and effectively cut food items, they become potential safety hazards as you exert more force to try to get the job done (which oftentimes means you lose the control you have over them). Now, there are several different tools that can be used to sharpen them but this guide is going to put an emphasis on both manual and electric knife sharpeners. So, if you are ready for the ride, let’s get started.

Criteria Used for Evaluation

Effectiveness

Seriously, what good would one of these do if it could not sharpen your knives?

The entire purpose of this tool is to sharpen your knives, right? Well, would it not then make sense that you need to prioritize how effectively any given mode does just that? This is really not rocket science and when it comes down to assessing this, you really need to pay attention to the materials. Do note, this is alluding to the materials that will actually be used to perform the sharpening (not the housing). In the world of knife sharpeners, there are four that stick out. The two most effective are carbide and diamond flecks. Both materials are commonly used as abrasives for this type of a tool but many people actually believe that diamond is the superior of the two. While this is not set in stone, diamond does seem to create less friction which can lead to softer and more precise sharpening.
The other two are actually steel and ceramic but these two materials are better suited for honing. Essentially, the process of honing is merely cleaning up the edge of a blade and is ideal for blades that are already semi-sharp. Of course, looking past the materials, you also need to be aware that most options out there will be designed to run in two or three different stages. For example, this could start with an abrasive sharpening section, then to a fine one, and then finish with a honing section.

Ease of Use

Look for models that are optimized for simplicity.

The types of knife sharpeners that were displayed in this guide specifically omitted whetstones. And, quite frankly, this right here is the primary reason as manual and electric models will simply be more user-friendly to use. Now, as you also saw on this list, there are honing and sharpening rods that are available. But, for the most part, the two most popular are manual and electric knife sharpeners. Clearly, the primary difference between the two is in their operation. But, is one easier than the other?
To be honest, both types are tailored to be easy to use so this question is not that relevant. After all, manual models will typically use guides to achieve the perfect cutting angles and then all you need to do is slide the blade through in a sweeping motion. The same concept applies to electric models, yet they will be equipped with either sharpening discs or belts. These will then move on their own and will lessen the work for you. Technically, they may be the easier of the two. Oh yeah, and it is also never a bad idea to look out for sellers that include well-written instructions with their models.

Features

Most of the features you need to look for come down to the safety of any one model.

Whenever you are dealing with sharp objects that can penetrate inside your body, you need to be careful. It has probably been drilled into your head since when you were a kid but knives are sharp people, and they can hurt you and hurt you bad. Outside of actually looking for some key features, which will be touched on momentarily, the most important thing for you to remember is to always use precaution when you go to sharpen any type of blade. If you handle it with care then you should be fine.
However, if a knife sharpener is not optimized for safety, in the first place, then accidents can be more prone to happen. This makes it essential to look out for stabilizing features. Most models on the market that are designed to rest on countertops will be equipped with non-slip bases. Either that or they will integrate rubber feet and either way, they need to remain stationary while in use. Along the same line, for models that need to be held, look for ergonomic and non-slip handles.

Materials

For the record, this is in regard to the external materials that are utilized.

You may be wondering why this is a section when the materials were already covered in depth earlier. Well, as was mentioned before, the first section was used to talk about the materials that actually perform the sharpening or honing but this is in reference to the external materials. In other words, the external housings are what we want to focus on here. This is more than just a durability check, also, as certain materials naturally look better than others.
In the world of any type of kitchen appliance or tool, two of the most common materials you will see are plastic and stainless steel. Not too many of you are going to disagree that stainless steel is usually going to be the preferred choice due to its elegance, build quality, and aesthetic appeal. But, if you do happen to go with a model that has a plastic housing, ensure that the plastic is still high in quality (such as ABS plastic).

Size

Ideally, you probably want to save as much counter space as possible.

Why would you want to deal with a knife sharpener that is oversized and bulky? Would you not rather opt for a model that is compact? To follow up on this question, at least to the point of it being still usable? The reason we say that is some models are actually really, really small and will probably be hard to work with if you have larger hands. But, back to the point at hand, most models on the market are going to be optimized for travel and storage so that is a good thing.
This is especially important if you plan to store your new model in your kitchen as compact designs will allow you to do so in a wide range of areas. And, just to make it clear, this means you will want to be looking out for the physical dimensions (height, depth, and width) of any given model.

Compactness
With a 12-inch length and five inches of both width and depth, this is a little larger than other options but is nowhere near immense in size.

Overall

Read more

Effectiveness
Even though the angle is not adjustable with this model, it does utilize the power of tungsten carbide technology and this allows it to meet the demanding tasks of sharpening.

Ease of Use
It is almost pushed down your throats how simple this is and, for the most part, all the claims are accurate. All you really need to do here is make three swipes with the blade you need to be sharpened.

Safety Features
All sorts of features are implemented here and all of them enhance the safety of this unit. You have the non-slip suction base for stability, ergonomic safety handle for enhanced control and top side suction pad that provided additional stability.

Materials
As opposed to hardened steel, this right here utilizes tungsten carbide, which is a natural Earth element that is going to last much longer.

Compactness
Okay, so this is really, really small. It may even be too small if you have larger hands. Of course, on the flipside, storing this will be as easy as it will ever get.

Overall
That last point could be the game changer here. Even though this is very stable, it is also incredibly small and is simply not going to be optimal for all of you.

In addition to the fact that this is another electric model, it sports interchangeable guides and these allow for the most optimal sharpening angles possible. Of course, the main housing here is made of plastic.

Read more

Effectiveness
All the different adjustments can account for thick, medium, standard, and light blades, which is really nice.

Ease of Use
Thanks to the integrated blade guides, all the guesswork has been taking out. These same guides will hold the knives at the perfect angles so you do not have to worry about it.

Safety Features
No, this is not an unsafe design but the guards that adjust the angle can be pushed out of the way too easily. So, just be aware of this “issue”.

Materials
The good news is it is not as if you will be roughhousing with this unit. So, though it sports a plastic housing, it should be fine. Then again, if dropped from a noticeable height onto tile or wood flooring, it may not survive.

Compactness
When compared to the other options on this list, this is definitely one of the bigger units. It certainly is still pretty compact but you will need some room for it.

Overall
In many consumers’ eyes, this will be a great option thanks to its electric operation and adjustable blade selector. Of course, the external housing could have been made of superior materials.

Effectiveness
All in all, this is a two-stage design that both sharpens and hones blades. Overall, it performs as advertised and that is all you really can ask for.

Ease of Use
This is about as easy as it is going to get, yet again. Chef’s Choice definitely optimized their sharpener to be as user-friendly and simple as possible.

Safety Features
The end of this unit is designed with a convenient soft touch handle that can be used with both hands. It also features indents that allow for superior comfort.

Materials
With ceramic and tungsten carbide sharpening elements, the lower price of this is not indicative of the quality of the materials used.

Compactness
One reviewer described this as being “comically tiny” and at the end of the day, it can be seen as such. Looking at the glass half-full, finding a location for it will be pathetically easy.

Overall
Arguably the most appealing and compelling feature of this design is its simplicity. It may look like a child’s toy but it certainly is effective at what it does.

Back-to-back models from Chef’s Choice here except the difference with this one is it is electric. And, although it does not handle smaller knives all that well, it does pretty well with larger ones.

Read more

Effectiveness
Looking past the fact that this electric model handles larger blades better than smaller ones, it is another design that integrates a three-stage sharpening system.

Ease of Use
It is actually advertised that this is incredibly simple to use. Yet, some previous buyers have noted that it can take a bit of time to get accustomed to using this bad boy.

Safety Features
First off, this does sport rubber feet that prevent it from slipping. Additionally, there is a location in the middle where you can safely place one of your hands if you need to.

Materials
The honing and the sharpening slots use 100 percent diamond abrasives for hardness and as was mentioned earlier, diamond is an ideal material for such.

Compactness
At under a foot in length (nine inches) and less than four inches in depth, this is very compact and easy to both store and travel with.

Overall
The combination of the electric operation and the magnetic guides, this is one of the most convenient options on the entire market. Just give it a minute and you should have the basics down.

Out of all the options on this list, this one probably requires the most effort. This is simply because it is merely a sharpening steel rod that is connected to a rubber grip handle.

Read more

Effectiveness
The steel that is present here is going to refine your knives but it is probably not going to save super dull blades.

Ease of Use
This is not an automatic option but the square handle that is integrated does make it easier to hold. You will want to know how to operate this type of tool, though, so you may want to reference online videos.

Safety Features
The same handle that was just mentioned is also slip-resistant for enhanced grip and safety. However, the rubber utilized is not exactly top-end.

Materials
Looking past the mediocre rubber, the entire rod here is made of magnetic steel and is going to attract metal fibers.

Compactness
In addition to the fact that this can actually fit inside most knife blocks, it also features a hanging loop on the end.

Overall
For a lot of you, this right here will simply not be worth the effort. Much like an old-fashioned sharpening stone, this will require a fair amount of skill.
