How does it feel when you need to slice an onion using a cool kitchen knife that works only with your fingertip pressure? Have you ever experienced the cutting object slipping off your hand or cutting table due to the dull or misaligned knife?

These machines work best for kitchen knives and work well for pocket knives. For tactical knives, you will likely be better with another type of sharpener, which allows you to maintain entire control of the sharpening process.

Electric knife sharpeners usually feature two sharpening slots, along with fine as well as coarse sharpening openings. Nevertheless, a few manufacturers add an extra slot known as medium sharpening.

These slots come with installed abrasive disks spinning against the edge of the knife, while sharpening. Each of these disks is made using a certain material. The slots steer the knife, on one side initially, and then on the remaining, which needs practice to cut at the precise angle. The sharpening angles are fixed in a way such that the sharpener is able to act with versatility.

Due to this factor of versatility, an electric sharpener is perfect for sharpening knives having different levels of dullness. All you have to do is power the tool, turn it on, and pull the knife smoothly through the slots. Electric models can also sharpen serrated knives at high speed.

Best Electric Knife Sharpener: Before Looking for It

There are a few factors to consider before you go ahead and know about the different electric sharpeners. Doing so certainly eases out your task of choosing the one that fits your needs.

  • Types of existing knives, as electric sharpeners are ideal for sporting, pocket, and kitchen knives with straight edge or one-sided serrated edge (of the two, the serrated one dulls much slower than a normal straight edge one).
  • Cost of Existing Knives, as rare over wearing due to electric sharpeners is common in case of inexpensive knives, and that more expensive sharpeners are smoother on knives, including the most professional one.
  • Storage space, as lack of space indicates having a compact sharpener, as some of them might need a permanent space on the counter, while some easily fit in a drawer.
  • Your Noise Sensitivity, as a few electric sharpeners create noise, but that can be tolerable if you are too sensitive to the whetstone grinding sound.

Factors to Consider

While researching and looking for the best electric knife sharpener, you should consider the important buying factors affecting your selection. These factors typically revolve around your preference and sharpener’s features so that you strike a perfect balance between the two, for getting the one that exceed your expectations to keep the knife in effectively working state.

Electric knife sharpeners are undoubtedly beneficial and very effective, but they also come with a few more concerns. This is the case, because they’re equipped with so many additional components. The internal motor is one such component. With this in mind, it is essential to explore all of the characteristics of each sharpener, before you make your decision. Below, you will find a breakdown of each of these for your convenience.

  • Number of Stages: Investing in 3-slot sharpener is ideal for enjoying maximum versatility through just a single tool. In case of only two slots, you may need another tool for polishing the edges. Otherwise, at least have a 2-slot model for super sharpness after consuming some time. The first slot is with coarse material for old and dull knives, while the second one is for honing and refining the knives for finishing the look. If there is a finer slot, it is ideal for polishing and in between sharpening.
  • The Internal Motor: Each of these devices is equipped with an internal motor that does the work for you. It is essential to make sure that the motor is going to provide you with many years of service. You can do this, by reading knife sharpener reviews for these particular units. If you discover one that seems to breakdown quickly, you will want to stay away from it, at all costs.
  • The Angle: Go for an electric model that allows deciding the angle level for holding the edge at, while sharpening, in case you a beginner or learner when it comes to using a sharpener. Some models are made to help in this area, by automatically holding the knife at the precise angle. Choose the sharpener as per the knife angle. A western knife has an angle between 20° to 25°, while an Asian knife’s angle is over 15°.
  • Material of Grinding Stone or Abrasives: Diamond abrasives are best for having a razor-sharp, long lasting edge faster than ceramics, making the sharpener perfect for those who are new to sharpening. The only con is that diamond abrasives are not that better for an ideally straight edge and final polishing. This is the reason why the third slot will typically not have a diamond but rather a synthetic or ceramic material. If you wish sharpness quickly, consider an electric sharpener with one of the stages having the diamond sharpening wheels. After all, it is the hardness of the abrasive surface that indicates how quickly and well sharpening shall occur. Diamond is perhaps the hardest material, followed by tungsten carbide and polished ceramic.
  • Size and Weight: These factors are essential to check out for a better user experience although they do not affect the sharpening ability. Plastic electric sharpeners are lighter, but are not durable as those commercial-grade metal tools. At the same time, ensure that the base is non-slippery to guarantee protection to yourself.
  • Great Performance: A poorly performing electric knife sharpener triggers only frustration and knife damage. Therefore, it is best to see customer reviews and ratings for judging the effectiveness of the promising model.
  • Safety: Consider having a model that has some important safety features such as self-cleaning mode (no manual cleaning) preventing from sharpening the finger ends. In case you do not find specific features, ensure that the design and working process is as per the required safety to keep risks away.
  • Single- or Double-sided: Single side models deliver a flat, stronger bevel than a concave one and are ideal for serrate knives. However, they run the risk of occasional scratching. Double-sided models create concave bevels and are easier to use. Nevertheless, you cannot use them for chisel knives.
  • Easily Replaceable Parts: When selecting one of these products, you will want to ensure that it is going to provide you with many years of use. In order for this to happen, you need to choose one that has replaceable sharpening pads that can be removed and changed easily! If the process is too complicated, you likely won’t do it and the investment will become a waste. Therefore, it should be easy to change for your convenience.
  • Warranty: It is absolutely vital to make sure that the manufacturer offers a good warranty! Although this might not matter so much with the others, it does for the electric knife sharpener! The internal motor and other components, which move about, can wear out. Since more things can go wrong here, you will want to make sure that the manufacturer backs up their product with a lengthy warranty.
