The best Electric Knife: Our Picks

Guide: Questions you should ask yourself before buying an Electric Knife

What foods can you use an electric knife for?

You can use the electric knife for almost all kinds of food you want to cut in your kitchen.

This includes meat, fish and bread, which you can cut into exact slices. With this kitchen gadget, you can also chop fruit and vegetables appropriately. The electric slicer is also unbeatable for cakes and pies.

This kitchen gadget won’t even let you down when carving your pork or beef roast. For the best quality, however, you should always use the right blades.

However, there are foods for which the electric knife is not suitable. These include very soft foods in particular, because they could otherwise fall apart.

Did you know that the effectiveness of an electric knife comes from the fact that the two blades work in opposite directions?

Driven by an electric motor, this makes it easy for the electric knife to cut both very soft and harder foods without any problems.

Electric knives should also not be used for cutting bones because the blades can break over time.

What are the advantages of electric knives over ordinary knives?

You can cut food not only with electric knives, but also with various kitchen knives. But using a kitchen knife is often very tedious and imprecise to achieve the desired result. The electric knife, on the other hand, simplifies cutting and carving and usually delivers a satisfactory quality.

In general, electric knives have the following notable advantages over chef’s knives:

  • Faster work
  • More even cuts than with an ordinary knife
  • They do not let bread crumble
  • Cutting frozen food
  • Cutting is possible without much effort

Using electric knives also saves you time. For example, if you want to cut a baked duck into even slices with a normal chef’s knife, it will take you at least ten minutes. The same process with an electric knife, on the other hand, takes only one minute.

Frozen food cannot be cut with a normal kitchen knife either. Here, the electric knife has a clear advantage. Electric knives with additional freezer blades allow you to portion different types of food.

How much does an electric knife cost?

The price of electric knives depends on many factors. Depending on the model and where you buy the product, prices can vary.

Price range Description
from about 10£ Relatively good quality but low performance.
approx. 20-45£ Higher performance, accessories included.
from approx. 45£ Very good quality, performance usually not higher. Ideal for frequent use.

You can find the cheapest machines at discounters. There you get the cheapest models with good quality, but with rather low performance. Depending on the brand and performance, the cheapest products start at 10 pounds.

If you want to buy a better model with higher performance, you can expect prices between 20 and 45 pounds. Products in this price category even come with more accessories, such as additional blades for frozen products or knives with a serrated edge.

Of course, there are also electric knives above 45 pounds, but these models do not offer more power, but rather even higher quality and more accessories, such as natural wood stands or thumb guards for safe cutting.

Depending on what you want to use the knife for and how often, you have to decide how much money you want to spend on it. For example, if you don’t eat much meat and don’t cook every day, we recommend an electric knife with a universal blade, as the rest of your food can also be cut with normal cooking knives.

However, if you cook every day and eat meat frequently, we recommend an electric slicer with two blades because it will make your everyday cooking much easier.

Which are the best electric knives?

Whether an electric knife is good or not depends on a few factors. The best devices are made of a good blade material, have a high performance and have many accessories.

High-quality workmanship is a quality criterion for good electric knives. Good electric blades are made of high-quality stainless steel, so they are correspondingly durable. In the better models, the housing is also made of stainless steel.

Power is also an important quality criterion. Devices with higher power ratings are faster. The better devices start at 150 watts and can reach a power of 250 watts.

Electric knives can also be distinguished by the number of accessories. For example, better electric knives have a wide range of accessories

Mostly integrated are:

  • Several knives
  • Meat fork
  • Storage box
  • Wall bracket
  • Hanging loop

How can you sharpen your electric knife?

Not only chef’s knives, but also electric knives need to be sharpened. However, there are already self-sharpening blades on the market. To sharpen non-self-sharpening blades, there are various methods and means, such as sharpening, grinding, whetstones or ceramic knife sharpeners.

Simply pull your electric knife through the sharpener several times from both sides to get the best result. Then take a clean cloth and wipe the sharpened blades several times with a little oil.

Depending on what you are cutting, you should sharpen the blades more often or less often. In some cases, they become blunt more quickly than normal knives because these electric cutters usually cut faster with more force.

What Types of Electric Knives are there and which is the right one for you?

In general, all electric knives have the same design and can therefore only be distinguished by the type of blade:

  • Electric knife with one blade
  • Electric knife with two blades
  • Electric knife with freezer blade

All types of blades have both advantages and disadvantages, because they are all used in various applications.

Electric knives are true kitchen helpers in everyday cooking, which you can use without any problems and without much effort to cut many different types of food. You can use them to chop, carve, fillet or portion any type of food. Depending on the food you want to use the electric knife for, there are various models available.

In the next section, we would like to show you the special features of the individual electric knives so that you can find out which device suits you best. For this purpose, we will present all the models mentioned above and summarise their advantages and disadvantages.

How do electric knives with one blade work and what are their advantages and disadvantages?

The particular advantage of these electric knives is that this model is very affordable and easy to use.

This older electric knife variant belongs to the simple electric knives, which is why it is no longer widely used. This model is driven by an electric motor inside the housing. The knife attachment is plugged into the housing and cutting is done by vibrating the knife.

Advantages
  • great cutting results without much effort
  • inexpensive
  • handy
Disadvantages
  • not suitable for frozen food
  • low quality
  • lower performance
  • noisy

These electric knives are among the first electric knives on the market and are therefore simpler and cheaper than the modern models with two blades. Electric knives with one blade are often available from discounters.

Depending on the brand, electric knives offer different quality. For example, you may notice some differences in the way they cut. Some electric knives are slower than others or are not sharp enough to cut harder foods.

In addition, the power of these electric knives also seems low. For these standard models, the power level is roughly between 100 watts and 150 watts. Nevertheless, these electric knives are perfectly adequate for a household. You can use them to chop many foods without any problems. This includes meat and fish, for example, but also fruit or vegetables.

Electric knives with a universal blade are simple and are therefore no longer manufactured very often. These standard electric knives only have a universal blade. You should note, however, that electric knives with one blade are slower than electric knives with double blades.

How do electric knives with two blades work and what are their advantages and disadvantages?

Electric knives with double blades enable much faster cutting because they consist of two blades that move against each other at the same time.

This is a more modern version of the electric knife. This model is also powered by an electric motor, but there are two blades next to each other that move in opposite directions. These double blades are much sharper and the teeth are also much finer.

Advantages
  • versatile
  • precise cuts
  • higher performance
  • different blades available
Disadvantages
  • using the wrong blades poor quality
  • risk of injury from the blade
  • higher price category
  • noisy

A particular advantage of these e-knives is that their double blades can be freely exchanged as needed. Indeed, different blades are available for different types of food. For example, there are special blades for bread and some for meat. So this electric knife is also suitable as a bread knife.

With this electric knife you can, for example, cut super-thin pieces of meat and the meat will not fall apart. These knives are also excellent as bread knives. You just have to change the blades. You can even fillet fish with this kitchen gadget.

Depending on the brand, you can get electric knives with different power. The motor of this variant has a power rating of between 100 watts and 250 watts, but the power consumption of this variant is significantly higher.

However, make sure that you use the right blades. For example, it is very difficult to cut bread with the blades for meat and vice versa. If you use the wrong blades, the meat fibres may be shredded and the slices may not be cut cleanly.

Electric knives with double blades are faster and more precise than electric knives with one universal blade. The interchangeable blades make the work easier.

How do electric knives with freezer blades work and what are their advantages and disadvantages?

Electric knives with freezer blades are thicker and therefore more robust than standard electric knives with two blades, making it easier to cut frozen food.

This type of blade works in the same way as the electric knife with double blades. To use the frozen blade, you just have to change the blades.

Advantages
  • stronger teeth
  • high quality
  • uncomplicated cleaning
  • quick work
Disadvantages
  • different brands, different quality
  • higher power consumption
  • noisy

Electric knives with a freezer blade are very practical because frozen food can be portioned conveniently with the freezer blades. However, you should pay particular attention to the brand, because not all brands deliver the same quality. With some models, you have to thaw the frozen food first before you start cutting it.

Another disadvantage is that this model consumes more electricity than a standard electric knife, because cutting takes more time. In general, the power of these electric knives is also about 150 watts.

Electric knives with a freezer blade are very practical if you also want to portion harder or frozen foods.

Buying Criteria: You can compare and evaluate Electric Knives based on these Factors

Have you decided to buy an electric slicer? Then there are still a few things to consider. In this section we would like to show you which factors you can use to compare and evaluate electric knives. This will make it easier for you to decide whether a particular device is right for you or not.

The most important purchase criteria are:

In the following, you will get a broad overview of the individual purchase criteria so that you can better evaluate the products.

Blade material

When buying an electric knife, it is important to pay attention to good quality. This is because the durability of the blades depends, among other things, on the quality of the blades. The best choice here is stainless steel. The blades should be made of high-quality stainless steel so that they are correspondingly durable.

Stainless steel blades are dishwasher safe. This means that if they are made of stainless steel, you can wash them in the dishwasher without any problems.

Stainless steel is durable, resistant and does not rust. These properties are particularly important for electric cutting knives. Therefore, look for high-quality blades so that you can use your electric knife for a long time. Electric knives made of high-quality stainless steel are more expensive, but the high quality always pays off in the long run.

Volume

The only disadvantage of almost all electric knives is the noise they make. Of course, they don’t cut silently, but some devices, especially electric knives with freezer blades, make a really annoying noise.

Otherwise, the volume does not depend on the type of blade. Both electric knives with a universal blade and electric knives with double blades can be just as noisy.

Nowadays, however, manufacturers offer various electric knives that are less noisy. For example, models from Rommelsbacher, Severin and Tristar are much quieter than models from Tefal. So if you often want to use your electric knife, you should look for a quieter model so that you don’t disturb your family and guests with the constant noise.

Power

As mentioned above, power is an important quality criterion. The power of the electric slicer determines the strength with which the electric knife can cut food.

In most cases, the power of the electric slicer does not depend on the type of blade. For example, not only electric knives with a universal blade, but also electric knives with double blades provide the same power. On the other hand, electric knives with freezer blades need a higher power rating.

The simplest devices start at 100 watts. However, this power is sufficient for most applications. But the power with a higher wattage is better. This is because these devices are faster and lighter. The higher the power, the easier the cutting.

Electric knives with freezer blades should also have a higher wattage to make it easier to portion frozen food. So for frozen food, you should choose a little more power. Manufacturers therefore offer electric slicers with freezer blades with a wattage of up to 250.

Depending on what you want to use the electric knife for and how often, you should choose a suitable electric knife. For occasional use, 100 to 150 watts are sufficient. However, if you want to use your electric knife more often, you should choose a device with a power rating of over 150 watts.

Power supply

Electric knives are available either with a cable or with a rechargeable battery. We have briefly described the advantages and disadvantages of both types in the following table:

Energy supply Description
Cable The electric knife with cable is tied to a socket, so it cannot be used everywhere. However, it is immediately ready for use when the 1.5m to 2m long cable is plugged in. The direct connection gives the electric knife more power.
Battery You can use the electric knife with battery anywhere and at any time. However, you should make sure that the battery is charged first.

An electric knife with a cord can only be used in the kitchen. However, this means that the electric knife has more power. You can work with this knife at any time because you don’t have to worry about whether it is charged or not.

With the corded models, however, make sure that the cord is long enough to be able to use the electric knife easily. The cable should ideally be 1.5 – 2 metres long.

If you don’t only want to use your electric knife in the kitchen, an electric knife with a rechargeable battery is the best choice. An electric knife with a rechargeable battery offers you more flexibility. You can use the electric knife right at the dining table to cut up any food, roast meat and portion cakes without hindering your guests and yourself with a cable.

An electric knife can also be used outdoors. Whether you are attending a birthday party or a barbecue, an electric knife with a rechargeable battery is the best choice outdoors. However, you should make sure to charge the battery regularly.

Safety switch

An electric knife is dangerous because you can seriously injure yourself with it. However, if there are children in the house, it is a good idea to choose an appliance with a safety switch.

Nowadays, a safety switch on an electric knife is a matter of course. You will not find any electric knives in the various department stores or electrical shops that do not have a safety switch. However, if you want to buy a used older model online, you should make sure that the electric knife you choose has a safety switch.

Most electric knives have a safety switch on the handle. If you keep this switch pressed, the knife will work. As soon as the switch is released, the knife switches off again.

In addition, most electric cutting knives are also equipped with a finger guard and a blade release button. Using the eject button, the blades can be easily removed from the device without suffering any injuries. These extra functions are very important in order to work with the electric knife in a protected manner.

Design

Especially with electric knives, design plays a major role. For example, you will use an electric knife with a rechargeable battery not only in the kitchen, but also at the dining table or outdoors in front of your guests. The design is divided into two elements:

  • the colour of the electric knife
  • the shape of the electric knife

Most electric knives are available in white. But if you prefer a different colour, you can also get certain electric knives in black or silver.

As for the shape of the electric knives, electric knives with double blades have a nicer design than electric knives with one universal blade. This is because these electric knives are among the first models on the market, which is why they are characterised by a simple design.

Extra features and functions

Nowadays, many electric knives are equipped with various extra features and functions. These extras are always very practical and therefore you should always consider them when looking for the right electric knife.

The extra features include storage boxes and storage bags, which ensure the highest possible safety. In addition, protective covers and hanging loops are also practical so that your electric knife is always ready for use.

If your hands are small, electric knives with soft-touch handles are the best choice. The electric knife fits comfortably in your hand thanks to this rubberised handle. This makes cutting no longer a chore.

Did you know that electric knives have developed steadily since they were invented a few decades ago?

The electric knife has not only become an integral part of many private kitchens at home, but also in butchers’ shops and restaurants.

Brands

Nowadays, many manufacturers produce different electric knives of good quality. Models from Moulinex, Severin, Rommelsbacher, Clatronic, Tefal or Gastroback are important to mention.

These manufacturers offer electric knives that have important special features. It is therefore important to find out about the models of the different brands before buying.

For easily decaying food such as onions, an electric knife is rather unsuitable, as the risk of injury increases due to possible slipping.

Facts worth knowing about Electric Knives

Who are electric knives suitable for?

Electric cutting knives are suitable for all people who prefer fast, precise cutting of various foods in their everyday life. In addition, the use of electric knives is also very helpful in the catering sector.

With electric knives, fast work is guaranteed. This is enormously important, especially in catering establishments, because guests should always be served high-quality food. This high quality is guaranteed by using the electric knife.

How should you handle electric knives?

Note: Regardless of whether you use electric knives with one universal blade, with two blades or with freezer blades, be aware of the possible risk of injury! Always follow the safety instructions!

The electric knife usually has a safety switch on the handle that you have to press to “lock” the knife. This prevents the electric knife from switching on by itself if you accidentally touch it.

Blades made of stainless steel can either be cleaned by hand after use or simply put in the dishwasher. However, the housing should not be cleaned in the dishwasher, but simply wiped with a cloth.

Keep your electric knife away from children. Therefore, always keep the cleaned blades and the working part separate.

What alternatives are there to electric knives and what are their advantages and disadvantages compared to electric knives?

The main alternative to electric knives is the slicer. All-purpose slicers have similar functions to electric knives, but the all-purpose slicer offers much stronger performance and better cutting results.

With slicers you can really cut all kinds of food. You can also manually set the desired width of the slices. This way you can easily cut thinner or thicker slices depending on your needs.

Besides the many advantages, there are also some disadvantages that an all-purpose slicer has compared to electric knives. Firstly, an electric knife is more mobile because you can use it right at the dining table. Secondly, the electric knife is easier to use than the universal slicer.

Unlike the universal slicer, you can operate the electric knife with one hand. The risk of injury is also much higher with slicers. These machines not only cut food, but are also dangerous for your fingers. Therefore, all safety regulations should be observed.
