Rate this post

A good knife is a cook’s best friend. They speed up kitchen prep and, when used appropriately, make it safer! Our knives are a wonderful investment in our kitchen and are essential for meal preparation and serving.

Maintaining a nice set of knives, including keeping them sharp, is an important aspect of having them. Instead of using a manual sharpening to polish your knife’s edge, use an electric sharpener to save time and work.

These useful tools include a variety of characteristics, such as variable sharpening angles, and not all of them operate with all types of knives, such as serrated or ceramic blades.

We remove the guesswork from your search by analyzing some of the top electric knife sharpeners to assist you in making the best option for the lifespan of your blades.

Top 11: Best Electric Knife Sharpeners

1. Chef’s Choice 15 Trizor XV EdgeSelect Professional Electric Knife Sharpener

This device includes a sophisticated stropping or polishing step as well as 100 percent diamond abrasives for sharpening straight-edged and serrated knives.

It should be noted that it is not advised for ceramic knives.

It is simple to use, with flexible spring guides, automated adjustment, and precise control over the sharpening angle. This handy tool can handle the thickest and thinnest knife blades, ensuring razor-sharp edges.

The Chefs Choice 15 Trizor XV has a three-stage EdgeSelect system that does the following:

  • Stage 1: Diamond abrasives on conical disks form tiny micro-grooves on both sides of the edge, giving the knife greater bite.
  • Stage 2: Finer diamond abrasives are used on the conical disks that form the second and smaller bevel of the edge, resulting in even finer micro-grooves at a somewhat wider angle.
  • Stage 3: By establishing a third and even smaller bevel of the edge, a revolutionary, flexible abrasive stropping disk technique is used to achieve a microscopically smooth, non-serrated, ultra-sharp edge. This stropping motion polishes the edge even more, resulting in an edge with outstanding sharpness, performance, and longevity. It may also be used to sharpen serrated knives.

Sharpening for the first time takes roughly one minute, while re-sharpening takes about ten seconds.

It will also transform your blades from the usual 20-degree factory edge found on household knives to the Trizor XV 15-degree edge, which Chefs Choice claims makes the knife easier to wield and helps it last longer.

Although it may be used on hunting knives, keep in mind that they will also be transformed to a 15-degree edge.

2. Work Sharp Culinary E3 Electric Kitchen Knife Sharpener

The Work Sharp E3 has a two-speed electric sharpener as well as a ceramic honing rod.

The electric sharpener has two speeds: one for sharpening dull knives and another for polishing the edge after sharpening or for rapid touch-ups.

The E3 also has sharpening guidelines, which reduce uneven sharpening and take the guessing out of sharpening your knives.

Work Sharp claims that your knife will be sharp in 90 seconds or less, and that this gadget will not harm your blades.

The leather-lined guides are designed to gently grasp your blades. The guides are positioned at a 17-degree angle, combining the toughness of Western blades with the accuracy of Eastern knives.

The flexibility of the sharpening belts is the same technology used by professional services and manufacturers, and it will help to maintain the quality and worth of your kitchen cutlery.

This tool is distinctive in that it features a separate ceramic honing rod capable of producing ultra-sharp blades and retouching edges between sharpenings. Honing may help to keep blades sharp and lengthen the time between sharpenings.

The Work Sharp E3 knife sharpener can sharpen every kind of knife in your kitchen, including chef knives, paring knives, carving knives, serrated knives, and more. It should not be used to sharpen ceramic knives.

3. Wusthof 3-stage PEtec Electric Knife Sharpener

Wusthof is a well-known knife company that manufactures high-quality German kitchen knives. Wusthof has teamed up with Chefs Choice to create an electric sharpener featuring Precision Edge Technology (PEtec). Straight and serrated blades may be sharpened, honed, and polished using this device.

This sharpener features three stages:

  • Stage 1: A diamond abrasive wheel that sharpens dull knife blades.
  • Stage 2: A finer diamond grit wheel will be used to sharpen and improve the edge.
  • Stage 3: Advanced stropping substance for polishing the blade to a razor-sharp edge and sharpening serrated blades.

This sharpener was not designed only for Wusthof knives. It may be used with any western-style knife to generate the 14-degree edge seen on Wusthof blades. It should not be used on ceramic knives.

More possibilities may be found in our Wusthof knife sharpener reviews.

4. Kyocera Advanced Ceramic Electric Diamond Knife Sharpener

The Kyocera sharpener is one of a kind since it is battery operated. Unlike many of the others on this list, it is also intended for ceramic and steel blades.

With an electric driven diamond grinding stone rated at #600 grade, it can remove up to 0.5 millimeters off a blade while maintaining a 35-degree angle. Because it retains the knife at a constant angle, the knife placement or guide slot is user-friendly and safe.

An assist roller maintains equal pressure and minimizes over-sharpening. There is also a safety cover that keeps the grinding and dust confined.

An indicator light indicates that the item is turned on and operational. It does not come with the four AA batteries that it needs.

A terrific option for on-the-go cooks, the battery power allows you to use it in your RV and on long camping vacations in the great outdoors.

While it is perfect for Kyocera ceramic blades, it is not suggested for other Kyocera items. Make sure you don’t already have the following knives: KT-075-HIP-D, KT-200-HIP-D, FK-125N WH, or BK FK-181 WH or BK.

5. Presto 08810 Professional Electric Knife Sharpener

This Presto sharpener has a three-stage method that is appropriate for both kitchen and sport knives. The replaceable blade guides provide the best sharpening angles. With this sharpener, there is no guessing; the blade guides automatically hold the knife at the right angle.

To use, choose thick blades for hunting knives, medium blades for chefs knives or normal kitchen knives, and thin blades for light blades like fillet and paring knives. To produce a razor-sharp edge, pass the knife through each slot many times.

Each slot is a stage of the three-stage system:

  • Stage 1: This begins the sharpening process by creating the right angle using a Sapphirite coarse grinding wheel.
  • Stage 2: Sharpening with a Sapphirite medium grinding wheel continues to give the blade a precise edge.
  • Stage 3: This completes the process by polishing the blade to a precise, razor-sharp edge using an extra-fine grit ceramic wheel.

It is not recommended for use on ceramic knives.

6. LINKYO Electric Knife Sharpener, Kitchen Knives Sharpening System

The LINKYO system is simple to use, with automated blade placement instructions that keep the knife at the perfect angle. To use, move the knife gently towards you while applying no downward pressure.

In fact, it contains a built-in stop mechanism that stops the sharpener if too much downward pressure is exerted, assisting in the prevention of blade damage.

This system features two stages to sharpening:

  • Stage 1: Reshapes the angle and sharpens and revitalizes the edge.
  • Stage 2: The sharpening procedure is completed by honing and polishing the blade.

This equipment is simple to clean up after use, with receptacles that capture metal fragments and filings and easy-to-remove plugs to empty. It also incorporates non-slip suction cup feet to keep the sharpener securely in place as you sharpen your blades.

This product is not recommended for use with thick hunting knives or ceramic blades.

7. Electric Diamond Knife Sharpener For Ceramic And Stainless Steel Knives

This sharpener is manufactured by Shenzhen, a ceramic knife manufacturer, however it may be used with both ceramic and stainless steel blades. It comes with a diamond grinding stone with two settings: coarse (#600 grit) and fine (#800 grit).

The coarse setting is 18°, while the fine setting is 20°. The diamond grinding wheel can remove 1mm chips from ceramic blades.

It has a universal knife guide that maintains the knife at a constant, typical V angle. The slot supports most knife elements, including the blade, heel, bolster, and handle designs, enabling ceramic kitchen knives to be sharpened tip-to-handle.

It is not, however, suited for serrated blades or hunting knives.

The sharpener has two stages:

  • Stage 1: For a blade with noticeable nicks or rough edges. Sharpen the knife by gently guiding it through the slots on the coarse setting.
  • Stage 2 involves honing and polishing the knife. Repeat this operation with the fine setting slots for a smooth, sharp blade in seconds.

It features a replaceable diamond wheel cartridge as well as a cover.

8. McGowan Firestone Electric Sharpener

The McGowan sharpener offers a straightforward one-step precision sharpening procedure. Inserting the knife into the slot activates burned ceramic stones that sharpen both sides of the blade at the precise angle at the same time. This is due to the stones’ counter-rotating wheels. As a result, the hollow ground edge becomes razor-sharp.

It is ideal for all types of knives, including electric, kitchen, serrated, and cleavers, according to the maker. It is unclear if it is acceptable for ceramic knives.

The McGowan is unusual in that it forms an edge by rotating wheels upwards in the slot the knife is dragged through. The majority of them spin downwards.

Because the grinding wheels are at the front of the slot, you may sharpen practically any knife, even a pocket knife, because the sharpener does not interfere with the knife’s grip.

9. Smith’s 50005 Edge Pro Compact Electric Knife Sharpener

This device combines human and mechanical sharpening aspects and consists of two components: a sharpening wheel and crossed ceramic rods.

The sharpening wheels are comprised of bonded synthetics, which are intended to give extended wheel life, consistent cutting, and less heat buildup.

The crossed ceramic rods give the knife blade a final polished edge and produce a pre-set sharpening angle that softly hones both sides of the knife.

Sharpen the knife in the sharpening wheels before using the sharpener. The wheels sharpen just one side of the blade at a time, while the blade guides keep the knife at the proper angle.

The ceramic rods are then used for final edge honing by pushing the knife through the sharpening slot a few times. The crossed ceramic rods are also suitable for resharpening previously honed blades.

It cannot hold serrated or ceramic knives, and it cannot handle other objects such as scissors.

10. Edgecraft 130 Professional Knife-Sharpening Station

Chefs Choice manufactures this product, which has 100% diamond abrasives. It sharpens, steels, and strops most knife brands and varieties.

This sharpener is designed for 20-degree class knives and can sharpen both straight edge and serrated knives. Because it contains diamond abrasives, it should also be good for ceramic knives.

It has three stages:

  • Stage 1: Sharpens the edge of your knife by using revolving conical disks with 100% diamond abrasives.
  • Stage 2: With the help of precise angle guides and hardened minuscule steel, it generates a shaving sharp edge with ultra-sharp microscopic serrations. Stage 2 may be used as often as you want to keep a continuous razor-sharp edge until Stage 1 sharpening is required.
  • Stage 3: Using a flexible abrasive disk technology similar to a high-tech barber strop, it produces a microscopically smooth, ultra-sharp fine edge. It may be used as often as necessary to keep edges polished and maintained until further sharpening is required. It may also be used with serrated blades.

Precision angle guides are included throughout all three stages to reduce guessing and achieve consistently sharp edges.

11. Work Sharp Knife & Tool Sharpener

This gadget promotes itself as an all-in-one sharpener for your whole house. It is capable of handling a wide range of knives, including culinary, hunting, filet, outdoor, tactical, and pocket knives. Straight blades, curved blades, re-curved blades, tanto blades, and almost any other kind of blade may be sharpened. Diamond belts appropriate for use with ceramic blades may be purchased separately.

It has three premium abrasive belts:

  • The coarse belt is used to sharpen cutting instruments and restore broken blades.
  • The medium belt is used to sharpen knives in general.
  • The fine belt is used to hone knives, sharpen serrations, and conduct rapid touch-ups on previously sharpened blades.

Sharpening guides provide quick, simple, consistent results and are replaceable, allowing you to produce exact cutting angles. They are 40, 50, and 65 degrees, and are intended for various tasks, or they may be removed to sharpen instruments free-hand.

This machine can sharpen knives, scissors, serrated knives, and cutting instruments such as axes, hatchets, mower blades, garden shears, and shovels. This is a great device for someone who needs more than just a kitchen knife sharpening. Replacement belts are also available for purchase.
