Electric knife sharpeners can damage knives, especially Japanese knives, which are prone to chipping
Electric knife sharpeners can be a quick, easy, and safe way to sharpen your knives. However, they can also damage knives, especially Japanese knives, which are prone to chipping.
Japanese knives are typically made from a carbon-steel blend, which is harder than stainless steel. This allows them to hold a sharper edge, but it also makes them more susceptible to chipping or cracking. Electric sharpeners can be too abrasive for these delicate blades, removing more steel from the edge than necessary and causing the knife to wear down over time. This is especially true if the electric sharpener produces significant levels of heat, as this can easily damage the delicate edge of a Japanese knife.
Additionally, Japanese knives often have a single bevel edge, while most electric sharpeners are only suitable for double bevel knives. Using a single bevel knife on an electric sharpener will result in a damaged blade profile that can no longer hold a sharp edge and may even become misaligned with the knife handle, rendering it unusable.
Even a slight twist of the wrist when using an electric sharpener can cause a Japanese high-carbon knife to chip due to its small contact point to distribute force. This is less of an issue with softer steel knives, which don't chip as quickly. It's also difficult to know what grit and materials are used in electric sharpeners, and the knife's high-carbon steel may be harder than the material used in the sharpener.
While electric sharpeners can be convenient and time-saving, they are not well-suited for the delicate work required when sharpening Japanese chef knives. Manual sharpeners, such as whetstones, offer more control and are the traditional and preferred method for sharpening Japanese knives.

They don't produce a special edge, and you don't need them
Electric knife sharpeners are often advertised as a convenient and easy way to sharpen your knives. While they can be faster and more powerful than manual sharpeners, there are several reasons why you may not need one. Firstly, they don't produce a special edge. Electric sharpeners consistently create a basic edge of ""decent" working sharpness at fixed angles. The guiding angle cannot be adjusted, so you are limited to the thickness of the edge it produces. This means you can never choose to have a very thin edge for more precise cutting, or a thicker edge that will last longer.
The inability to adjust the guiding angle is a significant drawback, especially when compared to freehand sharpening. With freehand sharpening, you have more control over the angle and can create a sharper and more precise edge. This is particularly important for Japanese-style knives, which often have a single-sided bevel and a lower sharpening angle. Electric sharpeners can also be too harsh on these knives, causing chipping and damage due to the small contact point and force distribution.
Additionally, you may not need an electric sharpener if you don't use your knives frequently or if you have a small number of knives. For occasional sharpening, manual methods such as whetstones or sharpening services can be sufficient. While electric sharpeners offer convenience, they are not necessary for everyone. It's important to consider your specific needs and preferences before investing in one.
Furthermore, electric sharpeners may not be suitable for all types of knives. As mentioned earlier, Japanese knives with specific angles and bevels may not be compatible with electric sharpeners. Higher-quality knives may also be better maintained through other methods, as electric sharpeners can remove more material than necessary and alter the established edge. It's essential to understand the characteristics of your knives, such as the type of steel used, to determine the best sharpening approach.
In conclusion, while electric knife sharpeners offer convenience and ease of use, they don't produce a special edge, and you may not need one. They have limitations in terms of angle adjustment and edge thickness, and they may not be suitable for certain types of knives. For those who require more precise sharpening or own higher-quality knives, alternative methods may be more appropriate. Considering your individual needs and knife characteristics will help you make the right decision.

They don't allow you to adjust the guiding angle, so you can't choose between a thin or thick edge
Electric knife sharpeners are convenient, easy to use, reasonably priced, and can make sharpening knives faster. However, they have limitations when it comes to adjusting the guiding angle, which is a crucial aspect of knife sharpening.
The guiding angle, or sharpening angle, determines the type of edge that is put on the knife. A razor-thin edge is sharper but dulls more quickly, while a thicker edge is more durable but doesn't cut as nicely. Electric knife sharpeners consistently produce a basic edge of "decent" working sharpness at a fixed angle, which is typically around 15 to 20 degrees. This lack of adjustability means that users cannot choose between a thin or thick edge for their knives.
For example, the Chef'sChoice 1520, a top-performing electric knife sharpener, offers separate settings for 15- and 20-degree angle sharpening. While it provides some versatility, it still does not allow for a full range of angle adjustments. Other electric knife sharpeners may have only a single angle setting, such as 17 degrees, which further limits the user's ability to choose the desired edge thickness.
This limitation may be a significant drawback for chefs or knife enthusiasts who require specific edge geometries for different types of knives and cutting tasks. For instance, Japanese knives often have different angles on each side, and electric sharpeners may not accommodate these variations. Additionally, electric sharpeners can remove too much metal, causing permanent damage to knives, especially if the user cannot control the amount of material removed during the sharpening process.
While electric knife sharpeners offer convenience and ease of use, their lack of guiding angle adjustability can be a significant disadvantage for those who require precise control over their knife edges. This limitation may lead users to explore other sharpening methods or invest in higher-quality electric sharpeners with more advanced features.

You can't see what's happening inside, so you might mess up a good edge
Electric knife sharpeners are convenient, easy to use, reasonably priced, and can quickly sharpen a knife. However, one of the main concerns with electric knife sharpeners is that users cannot see what is happening inside. This lack of visibility can lead to potential issues, such as messing up a good edge or removing more material than necessary.
When using an electric sharpener, the guiding angle is fixed and cannot be adjusted. This can be problematic as it limits the user's ability to choose the desired thickness or thinness of the edge. A razor-thin edge, for example, will be extremely sharp but will dull more quickly, while a thicker edge will last longer but may not cut as effectively. Electric sharpeners consistently produce a basic edge of "decent" sharpness at consistent angles, leaving users with no control over the outcome.
The inability to monitor the sharpening process inside the electric sharpener means that users cannot detect if they are removing too much metal or changing the knife's edge in an undesirable way. This is especially concerning for high-quality or Japanese knives, which often have specific designs and angles that may not align with the fixed settings of the electric sharpener.
Veteran cook Chad Ward warns against using poor electric sharpeners, stating that they can cause permanent damage to knives. He notes that while some electric sharpeners, such as those from Chef'sChoice, are well-designed, others can give the entire genre a bad name. This variability in quality and the lack of visibility into the sharpening process can make it challenging to trust that an electric sharpener will produce the desired results without altering the knife's original edge.
While electric sharpeners offer convenience and speed, they may not be suitable for all knives or users who desire specific edge types. It is important to consider the potential risks of using electric sharpeners, especially for those who have invested in higher-quality knives.

They can be unsafe, as they move around during sharpening
Electric knife sharpeners are not ideal for several reasons. One of the main problems with electric knife sharpeners is that they offer only one angle setting, and the guiding angle can never be adjusted. This is a significant issue because it means that users cannot choose the thickness of the edge of their knife. Sometimes, a razor-thin edge is required, which will be extremely useful but will dull more quickly. On other occasions, a thicker edge is needed, which will last longer but not cut as nicely. Electric knife sharpeners consistently place a basic edge of "decent" working sharpness at consistent angles, and users are unable to choose the thickness of the edge.
Another issue with electric knife sharpeners is that they can be unsafe. During sharpening, they tend to move around, which can be dangerous. This is a safety concern, as it could lead to accidents and injuries.
The inability to adjust the guiding angle is a significant drawback of electric knife sharpeners. This limitation can affect the performance and versatility of the knife. Users who require different edge thicknesses for specific tasks or ingredients may find that the fixed angle does not meet their needs.
Electric knife sharpeners can also damage the blade. The abrasive materials used in the sharpener may be harder than the knife's steel, causing chipping or uneven wear. The high speed and constant contact of the rotating stones can also generate heat, affecting the knife's temper.
In conclusion, while electric knife sharpeners offer convenience and ease of use, they have several drawbacks. The inability to adjust the guiding angle, safety concerns due to their movement during sharpening, potential damage to the blade, and limited versatility affect their overall performance and user experience.
