Here is the deal; nobody ever loves working with a blunt knife. You do not have to be a professional chef to enjoy slicing, chopping or dicing with a razor-sharp knife. Even an ordinary amateur like me and you never really appreciate a dull blade in our kitchen accessories.
Most knives are bought sharp but get blunt after a while. You, therefore, have to sharpen the blades regularly for easy slicing of meat. But what do you use? Traditional methods tend to be too time consuming and require certain skills to pull off.
So what is the solution? Use an electric knife sharpener to hone the blades within seconds or minutes. They not only save time and keep you safe from the sharp edge but also shield the knives from damage by removing a consistent layer of metal.
Choosing the best electric knife sharpener is what troubles most consumers as the market is rich in these devices. Making a choice, therefore, becomes a bit harder. In this buying guide, we will highlight all that you need to know about electric knife sharpeners.
Pros and Cons of Using an Electric Knife Sharpener
A knife is to some extent an extension of your hands. A sharp one projects your personality and cutlery skills. Since the invention of electric knife sharpeners, maintaining the sharp blades has been made easier.
However, if you have not bought one, you might be still grappling weighing the potential pros and cons of owning one. These are some of what to expect when using one.
Pros of an Electric Knife Sharpener
- Time Saving
Sharpening a knife manually or seeking a professional to do it takes some time. With an electric sharpener, all you do is plug it into the kitchen power outlet, draw the knife blade into the slots and then slowly drag the knife out. It’s as simple and quick as that.
If your knife is not too blunt, then this takes just seconds. But if it had become too blunt, then you will have to pass it through the slots multiple times. In whichever case, it still saves you valuable time.
- Requires No Skills
Operating an electric knife sharpener requires no special skills to perform. Provided that you know how to use the knife, determine when it is sharp enough and switch the device on, you are good to go. The same cannot be said of the manual sharpeners which need balancing of the blade.
- Saves You Money in the Long Run
If you usually take your knives to a professional for sharpening, then owning an electric sharpener will be cheaper in the long run. Although the initial cost of a sharpener is high, it won’t be as much as the cumulative total you would pay a professional.
- Does not Damage Knives
There are certain expensive knives which require extreme care when sharpening. This care is provided to a great effect by the best electric knife sharpener by removing a consistent amount of metal on either side of the blade.
When using a manual sharpener, it becomes hard to sharpen both sides at the same time. Such a maneuver may damage a delicate knife.
- Keeps You Safe
Using an electric sharpener needs you to hold the knife at the handle and drag it through the slots. The device automatically does all the sharpening work for you. It’s unlike some manual models which require you sometimes to hold the blade when sharpening. Any slip could lead to a cut from the sharp blade.
- Suitable for Various Knives
There exists an array of manual knife sharpeners and sharpening stones as well. However, none of these can be used to sharpen all the types of knives in your collection. I don’t think there is a sharpening stone you can use for both serrated and kitchen knives.
With an electric knife sharpener, you can be sure to hone most of your knives. It could be different blade materials and design; it does all these.
Cons of an Electric Knife Sharpener
- Expensive to buy
Electric knife sharpeners do not come cheap. More so, if you are looking for the high-end options ones with multiple slots for sharpening, polishing, steeling and stropping. These will easily cost you upwards of $100.
- Needs Care When Sharpening
If you do not take care, the sharpener could damage your knife. It is imperative you firmly hold the knife and avoid over pressing it down while passing it through a slot. Doing so could lead to an overgrind and scratches on the blade.
- Occupies Considerable Space
Some electric knife sharpeners are not as compact as the manual ones. They, in turn, occupy more space on your kitchen tables. Some are also bulky and big.
Although they have a fair share of disadvantages, the pros out rightly outweigh these cons. When in need of a razor shape knife, you need a sharpener that is quick, efficient and keeps you from cutting your fingers. They are, therefore, a worthy investment for you if you are a knife person.
How to Choose the Best Electric Knife Sharpener
To assist you in settling on the right sharpener for your kitchen needs, I have rounded up some of the things you need to consider before buying one.
- Sharpening Stages
A typical electric sharpener consists of 2 stages for sharpening a knife. The first stage is mostly for pre-sharpening the knife, while the second one is to polish and hone the knife blade. Each of these stages has a wheel for performing the specific functions.
In some cases, you can get a sharpener with extra stages, making them 3 or 4 in total. These added stages are meant to give the blade a razor-sharp edge or might be another angled slot. There are some options with a single stage, but you need to be wary of these.
Their course wheels remove unnecessarily more metal at once, thereby shortening your knives’ life span. However, if you want to sharpen a pocket or a utility knife, then the single stage sharpeners will do for you.
- Sharpening Slots
A knife blade has 2 sides that need to be sharpened to a certain uniform degree. To enable this functionality, electric sharpeners come with 2 slots on each of the wheels. This design makes it easier to sharpen both sides by turning the blade from left to right and not the device.
These slots provide for the sharpening of a blade to a specific angle depending on your knife type. For a European or an American knife, the angle should be honed to about 150. Knives vary in these regards though, but you always want slots which can deliver you the desired sharpness angles.
- Angle Guide
Even experienced knife sharpeners still need a device with an angle guide so that they can attain the previously mentioned angles. The guide is also meant to make sharpening a lot easier, more accurate and done faster. Always look for a machine with an angle guide on it.
- Abrasive Material
In any electric knife sharpener, it is the abrasive material which is responsible for doing the sharpening work. The components used in making the abrasive material to an extent affect the precision of the sharpening.
It could also determine the suitability of a quick touch sharpening or an in-depth re-sharpening. In this regard, there are wheels made from titanium, tungsten carbide, ceramic or diamond. Of these, diamond abrasives are the best for honing the sharpest edges.
Because of the unique property of diamond of not getting too hot when sharpening, knives are unlikely to be damaged in the process. A sharper, more durable edge is created in the process.
When shopping for a perfect electric sharpener, it is good to determine first the types of knives you will need to sharpen. Are they straight or serrated edges? What materials are the blades made from? You need to ask yourself these questions first, and then look for the most suitable sharpener.
Ordinarily, you would want a device that will handle most of the knives you have. Be it a carbon, stainless steel or an alloy blade; it should be versatile enough to do both. There are high end options which will be able to sharpen even serrated blades.
Electric sharpeners are known to have considerable weight due to the presence of the motor, sharpening wheels and the metals used in their construction. In whichever case, you need a device that you can easily move around.
Another issue is whether to go for a battery powered or one that is plugged in. A battery operated one allows you to use it on the go, but are less powerful. A good compromise would be to buy one that uses both batteries and can be plugged in.
The size plays a key role too. It should neither be too big to compromise on portability, nor too small to compromise on the functionality.
- Safety Features
With all the moving parts and a sharp knife, your safety should be of utmost importance. The device designs should be such that there is reduced risk of injuries while being used. Features such as non-slip rubberized feet or rubber-grip handle all work to this effect.
The rubber feet are a must to prevent the machine from moving about when in use. The handle is not common, but you can look for one, just to be sure.
- Cleaning Ease
After you have completed your work, you need to clean the entire metal residue left behind. Various designs use different cleaning methods, but should always get the job done.
There are options which require the use of a magnet for cleaning, but this process is tiresome. Alternatively, look for one with a removable residue tray or with a magnet fused in the tray. It makes for the easiest cleaning processes.
