The very first knife sharpening methods that we are aware of can be historically traced back to as far as 750 centuries ago. Modern Western knife sharpening as we know it today has its origins in Northern Italy, where “moletas” would offer their knife sharpening services in the Dolomite Alps. The very first moleta to offer their services in America did so in the year 1886. Today, there are thousands of electric knife sharpeners that customers from all around the globe can use to sharpen their knives with amazing precision in the comfort of their own homes. A sharper knife is a safer knife, due to the fact that a dull edge causes people to compensate with more force, which can be dangerous. The following knife sharpeners have been rated as some of the best on the market for their technological sophistication.

The Chef’s Choice 15 Trizor XV EdgeSelect electric knife sharpener has been designed for the sharpening of American, European, and age and-style knives. Both straight edge and serrated edge knives can be sharpened effectively well. This knife sharpener is capable of converting 20-degree factory edges into high-performance degree edges.

There are three stages, including abrasive strapping disc and diamond abrasives as well. For the convenience of the user, there are flexible spring guides that can be used to automatically adjust the angles in order to find the most appropriate angle for your particular specifications.

The knife sharpener can be operated with a simple on/off switch.

The three-stage process has been optimized for thorough sharpening and minimal metal removal, which is very helpful for ensuring that the lives of your knives can be extended as long as you need without damage. The diamond abrasives on the conical disk in stage I are able to create very fine micro-grooves, which gives the knife a much more powerful bite. At the same time, the diamond abrasives create the first major bevel on the arc-shaped edge of your knife.

At the second stage, there are even finer diamond abrasives on the conical disk that are used in order to shape the second, smaller bevel that contains a finer selection of micro-grooves. In the third stage, there is a flexible abrasive strapping disc system that is used to create a very smooth, sharp edge on a microscopic level.

The flexible abrasive strapping disc system creates the final bevel, while polishing all of the micro-grooves from the earlier stages. The third stage is used for sharpening serrated knives, and when it does so, every single one of the teeth straightened and sharpened immaculately.

One customer testified that this knife sharpener was very helpful for saving their Shun knife. The customer reported that they had first heard about this knife sharpener from an article in Cook’s Illustrated that reviewed the best knife sharpeners in the industry, in which this particular model was the 1st place result.

The customer had never before owned in electric knife sharpener, but because of Cook’s, they were confident that they wouldn’t be steered wrong. The customer had unfortunately damaged their very expensive Cane Onion Shun chef’s knife, so they decided to give the unit a try for restoring the knife to its former glory.

The customer read the instructions (which they described as being very well-written) and set forth in their attempt to repair the most valuable knife that they owned. The customer ran the knife through the number one slot approximately 10 times, and what they found was that their first pulls were not very well-conducted due to the fact that they were still getting a feel for the machine and the process of proper sharpening.

Even though their technique could have used some work, the customer reported that they were able to get most of the damage effectively accounted for. The customer decided to then give the knife 3 to 4 more pulls, and they were delighted to find that the Knicks were just about completely gone after the second session.

After running the knife through the second and third slots about six times, the customer reported that the knife had never been sharper. The damage was completely removed. Even though the customer did not have any more damaged knives that needed repair, they were so impressed by this knife sharpener that they chose to go to their neighbor’s house and sharpen their dull knives for them. Even though their neighbor’s dull knives were not Japanese, the knife sharpener was still able to give them an impressive 15° edge.

The dimensions of this knife sharpener are 12 x 6.2 x 6.4”, and it weighs 4.7. This knife sharpener can be purchased for the price of $159.95, a 24% discount from its standard list price of $210.00. All purchases come with a three year limited warranty.

#2 Silver pick (Runner-up): Wusthof 3-stage Chef’s Choice PEtec Electric Knife Sharpener

Wusthof 3-stage Chef's Choice PEtec Electric Knife Sharpener

*Price typically updated every 24 hours. Current price may be different.

The Wusthof 3-stage Chef’s Choice PEtec electric knife sharpener has been designed to sharpen, polish and home both street nosebleeds and serrated edge blades with equal effectiveness. This electric knife sharpener operates with three different stages. The first sharpening stage features a 100% diamond abrasive, which is capable of giving even the dullest of knives a brand new edge. The second stage slot features a diamond wheel with a much finer grit, which is used to both refine and hone the edge to an even greater degree of sharpness then before. The third stage features an advanced strapping material, which is used to polish the knife blade into razor-sharp perfection.

In addition to Wusthof knives, this sharpener is compatible with all Western-styled knives. All Western-style knives can be given Wusthof’s high-performance 14° edge. This sharpener draws its power from Precision Edge Technology, giving it enough laser-like precision to sharpen even serrated edges into brand new quality.

One customer testified that this particular sharpener does an excellent job of sharpening any knife that has a similar shape to Wusthof blades. The customer reported that it does take some practice in order to learn how not to gouge the starting spot, where the knife makes its first contact with the wheel.

The customer advised prospective owners to make sure that, with the first wheel, they keep the knife moving from back-to-front instead of up-to-down. Making sure to adhere to the proper movement pattern, according to the customer, can help to avoid grinding a notch in the blade. The customer reported that the second wheel, due to being much finer, is less likely to gouge.

The customer advised new owners to avoid using their favorite knife when they are just getting acclimated to the way that the machine operates. A delicate pressure should be applied instead of a hard pressure. The customer reported that as long as the user allows the sharpener to do most of the work, there won’t be anything to worry about.

The customer noticed that the machine was slightly noisier in operation than they had initially expected, but it wasn’t a serious problem. The customer advises that watching the demo, and carefully reading the instruction sheet, are very wise decisions for new owners.
The customer found that the very first wheel was the best for deep reshaping of the knife edge, especially if your knife sharpness has deteriorated after many years of coming into contact with a cutting board. If there are any knives that only have some light dulling, then the customer found that the second wheel would most likely be more appropriate than the first wheel for mild touch-ups.

This electric knife sharpener functions with 110 volts. The dimensions of this knife sharpener are 12 x 6 x 6”, and it can be purchased for the price of $149.95. All purchases come with a three-year warranty.

Pre-purchase considerations

SURFACE ABRASIVENESS

The best sharpeners that you can get for your money will have very hard and abrasive surfaces. Out of all of the different abrasive surfaces that you can use with a knife sharpener, diamond is generally considered to be the hardest sharpening material of all. After diamond, polished ceramic and tungsten carbide are the next hardest sharpening services. The abrasiveness of any sharpening surface is determined by the number associated with its grit. The higher the grit number, the more abrasive the surface is.

For example, 900-grit is much finer than 500-grit material. If you want to get the absolute best in knife sharpener for your money, then the very first thing that you need to look into is exactly what the grit number is of the sharpening surface material included in the machine. With a sufficiently hard and abrasive surface, the sharpener will be able to create a consistently smooth edge that doesn’t produce any unwelcome scratches on your blades.

SHARPENING STAGES

When it comes to the material that you use to sharpen your knives, you will have to consider multiple sharpening stages. The finer materials, with higher grit numbers, are used for touch-ups and polishing jobs. By contrast, the coarser materials, with lower grit numbers, are used to reshape the knife edges entirely on the more damaged or the all knives. Many customers find that it is wise to have a knife sharpener that provides both coarse and fine sharpening surfaces.

You want to avoid the mistake of using too much coarse material for your knife sharpening touch-ups, because this can lead to you losing more knife steel the necessary. So long as you have an adequate balance between the finer and coarse knife sharpening surfaces, you can always ensure that your knives can remain can consistently healthy over multiple sharpening sessions.

SAFETY FEATURES

Most likely, one of your priorities when using the knife sharpener is going to be making sure that you can use it without taking off any of your fingers in the process. The best in knife sharpeners will generally have adequate safety features that make it possible to use the knife sharper and without any worries of injuries. Manual knife sharpeners will allow you to avoid injuries by placing an effective barrier that protects your fingers from the sharpening apparatus.

Electric knife sharpeners, on the other hand, generally use a selection of reels and slots that direct the knife towards the belt instead of the hand that you are using to guide the knife towards the belt. Of course, you’ll be able to have the best safety when using a knife sharpener as long you make sure to sharpen your knives in a controlled fashion.

Sharpening the knife carefully and properly should always be prioritized over sharpening the knife quickly, as trying to sharpen the knife quickly can soon turn into never getting the knife sharpened at all due to a sudden trip to the emergency room.Most likely, one of your priorities when using the knife sharpener is going to be making sure that you can use it without taking off any of your fingers in the process.

Knife type, Noise and Free Space

Before investing in any knife sharpener, you’re going to want to make sure that the types of knives that you have are appropriate choices for the specific brand of sharpener that you are considering adding to your home. Different types of knives will interact differently with certain grades of sharpening surfaces offered by the wide selection of knife sharpeners on the market.

Also, you are going to want to deeply consider the noise created by the knife sharpener, particularly if you happen to reside in a communal building.

You are also going to want to take notes of the exact measurements of free space that you have in any part of your home that you plan on placing the knife sharpener, in order to ensure that you are able to easily set it up once you have it.
