— Buyer’s Guide —

Why Choose an Electric Knife Sharpener?

If you use expensive knives or have a high budget, it’s definitely worth investing in an electric knife sharpener. Many people prefer to use electric models due to their flexibility, speed, ease, and comfort that it provides.

Before Buying

Choosing the best electric knife sharpener is simple if you have done your homework right. Firstly, know the types of knives and bevel edges you need to sharpen. If you’ve American or European style knives with a bevel angle of 20 degrees or more, you should look for a knife sharpener suitable for that.

Japanese-style knives are 15 degrees with a harder steel blade. Using it on the sharpener with 20 degrees angle will damage the knife.

So the first thing is to check your knives first before getting an electric knife sharpener. Matching the correct angle guide of the sharpener to the knife bevel is the first step to choosing an electric sharpener. This will ensure you’ll get a great machine that will surely restore dull knives to crisp and razor-sharp.

Some models have a variable angle to adjust for different types of knives. These are some sharpeners that are worth investing in the long run. From Japanese Sushi knives to Wusthof Chef’s knives to hunting knives, all sharpened by one sharpener. The Work Sharp Knife Sharpener is worth considering in this case.

Professional chefs and veteran cooks loved this feature as they tend to sharpen many types of knives very often.

What is The Best Home Knife Sharpener?

This is a common question. But there is no definite answer.

As a matter of fact, there is no single knife sharpener that can accomplish everything flawlessly. Choose only what’s suitable for you based on the criteria that you set. This depends on your own unique requirements.

Below are some guides that can help you to make a better buying decision.

Your Budget

To most buyers, this is the key factor in deciding a purchase. The prices of electric sharpeners range from 20 something to more than 100 dollars or more.

As a general rule, if you rarely cook and are not particularly important about sharpening quality, then a cheap model is what you need.

On the other hand, if you loved to cook and always want to impress yourself and others with a razor-sharp knife. It’s always worth getting a mid to high-range sharpener to ensure sharpening quality.

Do Brands Matter?

Nowadays, electric sharpeners keep improving to gain the trust of consumers and market share. Manufacturers like Chef’s Choice and Work Sharp are the leading brands on the market. So rest assured you’re getting the best investment for years to come.

In general, reliable products always come from trusted manufacturers.

Size, Style, and Design

If you compare different brands, size does vary from one to another. It is appealing to buy the most compact size with the most features built-in. This will save space on your countertop.

And when it comes to color, most knife sharpeners are either black, white, or in stainless steel finish. It’s usually not an issue to blend well with the kitchen countertop. Reputed manufacturers have done enough surveys in terms of style and design to know what consumers want.

During the sharpening process, you’ll need one hand to hold the unit and another hand to pull the blade. Some models have a soft rubber grip on one side to ensure you can hold it firmly and some have rubber suction cups on the bottom to prevent sliding.

Are all these factors important to decide a buying decision?

Why not take a few minutes and make a comparison?

Grinding Material

Diamonds are one of the hardest minerals on earth and a great choice for a knife sharpener. Most electric knife sharpeners nowadays are equipped with diamond abrasives. If you want a sharpener to give you the best sharpening results, then you should look for a knife sharpener that is equipped with 100% diamond abrasives.

Ceramic abrasive is another hardest material besides diamonds to perfectly horn the knife razor-sharp. There are some models that come with 100% diamond abrasives and some combine diamonds with ceramic abrasives.

Tungsten Carbide and Steel are other types of grinding materials that are also popular in sharpeners.

Take your time to review the best sharpening abrasives according to your budget and needs.

Multiple-Stage Sharpener

Most sharpeners come with at least 2 or 3 sharpening stages, also known as knife blade slots.

For a 2-stage sharpener, stage 1 is for repairing the knife which means more metal will be removed from this stage. And the second or the last stage is to polish and horn the knife. It gives a final touch to the knife and makes it looks brand new! The polishing stage also removes all of the excess metal shards from the knife, making sure that you do not end up mixing pieces of metal while cutting up the food.

For a 3-stage sharpener, there is an additional stage in the middle. It serves as a medium polishing stage before the final stage so you’ll get a razor-sharp blade better than the 2-stage sharpener.

How about Serrated Knives?

Although both 2 and 3-stage sharpeners can sharpen serrated knives, it’s advisable to invest in a 3-stage sharpener. The additional stage to polish knives to hair-splitting sharpness will bring back their glory in one to two minutes.

Which to Choose – 2 or 3-Stage Sharpener?

Now the question is do you need a 3-stage sharpener to get the job done?

It depends on the usage and the types of knives you have. If you’ve cheap knives and only cook once a while, then we’ll recommend a 2-stage sharpener. Other than that, it’s advisable to buy the 3-stage sharpener to ensure sharpening quality every time.

You may come across some models that only have one stage (sorry, not included in this review). That means it only has the coarse sharpening stage and nothing more. We do not recommend it as you’ll get a badly-sharpened knife that feels rough and blunt as compared to other sharpeners. And do not try serrated knives on it as it’ll damage the serration beyond repair.


Do you want the sharpener to work on any type of edge other than just kitchen knives? Think about axes, lawnmowers, scissors, gardening, and other woodworking tools.

In our humble recommendations, the Work Sharp Ken Onion is a perfect choice for heavy-duty sharpening. It also has attachment options to further expand its sharpening capabilities.

Ease of Maintenance

The ease of cleaning is another factor to consider when buying an electric knife sharpener. When you sharpen a knife it leaves behind metal residue and it’s also important that it should be easy to dispose of.

No worries.

Most of the models have high-grade receptacles to collect the metal filings and disposing of it does not take much effort. It’ll take less than 1 minute to clear the residue.

In fact, electric sharpeners are quite easy to maintain. As it’s made up of high-grade plastic or stainless steel body, cleaning with a damp cloth is all that you need to make it shines.

How about the motor?

It requires no maintenance as long as you do not abuse it (running non-stop).


The warranty period does reflect the sturdiness and reliability of the sharpener. Most of the models come with a standard 1-year warranty while some will extend to 2 to 3 years. If everything (specifications and features) are being equal, getting a sharpener with a 3-year warranty is definitely worth the purchase.

How to Use an Electric Knife Sharpener

Using an electric knife sharpener is no big deal and with practice, you can easily learn how to do it. Most electric knife sharpening machines are equipped with a user manual with clear instructions. You should, however, be careful if you are using it for the first time and make sure the safety precautions are followed so that you do not end up hurting yourself or those around you.

Step 1

You should know the shape and style of the blade so that you are able to put it in right. The better you know the shape of your knife, the better you would be able to sharpen it. Flat knives are easier to sharpen than curved ones.

Step 2

Understand how your electric knife sharpener works. Read the manual which accompanies the machine. All sharpeners work differently, so you should be aware of how yours works. Even if you have used electric knife sharpeners before, it is still advisable to read the user manual for the new machine.

Step 3

You can now proceed to start using your machine.

  • Prepare!

Plug it in and turn the power on. Make sure it is placed on a flat, dry surface.

  • Sharpen!

You should know how much sharpening your kitchen knives require and which stage of sharpening they require. Most electric knife sharpeners start with a coarse stage for dull blades, then a finer stage for blades that are not too sharp or too dull, and then finally, a third stage for polishing.

  • Process!

Put the knife into the slot. Make sure you’re holding the knife down firmly but do not apply pressure. Let the weight of the knife sit in and have contact with the abrasives. Now draw the knife slowly and consistently toward you.

  • Make sure you run through the heel all the way to the tip of the knife. You need to repeat this process twice on each side, which means a total of four times.
  • Repeat this step in either the second or third stage to further hone and polish the knife. Switch off the power after completing the whole sharpening process to prevent the motor from heating up.

Step 4

Now check whether you have achieved your desired sharpness. Keep a tomato handy to check how sharp the knife is. If you’re not satisfied with the performance, repeat the same process again until you feel you have achieved the desired results. Once you are satisfied, clean your knife with water and towel dry.

Safety Aspects

Generally, electric knife sharpeners are quite safe, simple to use, and convenient. There are, however, certain safety tips that you should keep in mind.

  • Always read the user’s guide or the manual. Make sure you understand fully what the machine is all about and how to use it. Understand whether any preparations need to be done before using, and how to clean it up after you are done. Some people simply ignore this, but it is quite important.

That’s a big mistake.

Every model operates differently. And even if you have been using electric knife sharpeners before, you should still read the manual every time you buy a new machine or another model. It’s not surprising you can pick up some tips from the user’s guide to maximize the performance of the operation.

  • Never use electric knife sharpeners with water or any or any other lubricants or place it in any liquid. Make sure there is no water around while you are using the device.
  • Never use an electric knife sharpener that has a damaged plug or a damaged cord and do not try to fix it with electrical tape since it can be very dangerous.
  • Make sure you do not use the device near or around children and make sure it is out of their reach.
  • Always switch off the machine and take the plug off when you’re finished.
  • If the machine is meant for household purposes and cutlery, do not use it on other knives.
  • Make sure there are no hot surfaces around, and the power cord is not tangled.

As long as you follow these steps and make sure you’re doing what the instruction manual says, then you can use it safely and it would last for years!
