This model can handle mostly European knives but it’s a challenge to sharpen Japanese knives because of the higher bevel angle it imparts on blades. It’s also not recommended to sharpen smaller and paring knives.
While it has some limitations, the Presto 08810 can deliver a razor-sharp edge on most kitchen knives. The third stage or the honing stage is optimized to deliver such hair-splitting sharpness.

The first stage is a 100% diamond abrasive that turns dull knives really sharp in seconds. While this professional sharpening station actually produces the sharpness better than a new knife, it also uses the super-hardened miniature steel in stage 2 to create the microscopic serrations on the blade.
This unique feature will create the extra bite when cutting food to prevent it from sliding. It is mostly found in professionally steeled edges but it’s included in Chef’s Choice 130.
The third stage is also a 100% diamond abrasive flexible stropping disc to polish the blade to hair-splitting sharpness. Like many other sharpeners, serrated blades can also be sharpened in the final stage.

7. Wusthof PETEC 2933 Electric Knife Sharpener
Chef’s Choice has partnered with Wusthof to produce the PEtec 2933 electric knife sharpener. For those who haven’t heard of Wusthof, it is a German company founded in 1814 specializing in making high quality kitchen appliances, including knives.
So what’s so great about Wusthof PEtec 2933?
This 3-stage sharpener has no distinct difference from other similar chef’s choice models other than it sharpens blades down to 14 degrees edge. This is quite similar to the Chef’s Choice 15 Trizor XV.
Wusthof uses a new sharpening technique known as PEtec (Precision Edge Technology) for making knives. It combines laser-guided system with computer-aided software to deliver knives with super sharp edge before leaving factory.
What does PEtec have to do with this sharpener?
To be honest, we couldn’t find any relationship closely related to it. This sharpener does not come with laser-guided system and software to function. It’s a standalone unit. We believe it’s just a marketing strategy.
But one thing for sure is the 100% diamond abrasive wheels will definitely reshape and polish knives at its finest, ensuring exceptional sharpness.
Dull blades can be quickly reshaped to lease a new life in stage 1. You’ll have to know the types of knives you want to sharpen. For this thin angle, you’ll properly know that Japanese and Wusthof kitchen knives are well suited for this sharpener. Unless you intend to re-profile the American and European knives which have thicker blades, this is something to be aware of.
Stage 2 is a finer stage for honing and smoothen the blade after stage 1. It does not remove much of the steel as opposed to stage 1. And for normal sharpening, you can start with stage 2. You can get sharp blades with the fine grit diamond wheel in this stage.
The third and final stage always ensures exceptionally sharp and polished blade with the ultra-fine stropping discs. After passing through the three stages, knives are as sharp as new if not better.
The Wusthof 2933 electric sharpener weighs approximately five pounds which are considered light. You can store it away conveniently with measurement of 10 x 6 x 6 inches. And the powerful motor works consistently without a sign of slowing down. That’s means it’s close to a mini size with a big performing sharpener.
The non-slip rubber feet at the bottom prevent slipping and sliding during operation. That ensures stability and translates to precision gliding throughout the 3 stages when you pull the knives.
- Non-slip rubber feet
- Size: 10 by 10 by 6 inches
- Made by Wusthof (a trusted German company)
- 3-stage sharpening system
- 3 years warranty
- 100% diamond abrasive wheels

The diamond abrasive wheels incorporated with 14 degrees thin angle sharpening system deliver hair-splitting sharpness. For those who have a bunch of dull knives to re-profile to a new edge, the Wusthof 2933 is a quality sharpener worth buying.
8. Chef’s Choice 270 Hybrid Diamond Hone Knife Sharpener

The Chef’s Choice 270 is a hybrid sharpener that is capable of both manual and electric sharpening. It sharpens kitchen knives, sports and pocket knives with the standard 20 degrees angle edge.

Weighing merely 2.35 lbs, this sharpener is amazingly light. That goes with the dimensions of 9.125 x 3.75 x 3.125 inches.
Do you have a small kitchen countertop or storage room?
No worries. This compact size sharpener guarantees you can easily find a place for it.

— 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 the electric models due to their flexibility, speed, ease, and comfort that it provides.
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 the harder steel blade. Use 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 knife to Wusthof Chef’s knife to hunting knife, all sharpened by one sharpener. The Work Sharp Knife Sharpener is worth considering in this case.
The professional chefs and veteran cooks loved this feature as they tend to sharpen many types of knives very often.
What is The Best Kitchen 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.
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 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 to get a mid to high-range sharpener to ensure sharpening quality.
Do Brands Matter?
Nowadays, electric sharpeners keep improving to gain trust from 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 compared 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 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?
Diamonds are one of the hardest minerals on earth and a great choice for a knife sharpener. Most of the 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 combined 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.
Most sharpeners come with at least 2 or 3 sharpening stages, also known as knife blade slot.
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 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 its 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.
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 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.
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.
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.
You can now proceed to start using your machine.
Plug it in and turn the power on. Make sure it is placed on a flat, dry surface.
You should know how much sharpening do your kitchen knives require and which stage of sharpening they require. Most of the 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.
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 towards 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 on either second and third stage to further hone and polish the knife. Switch off the power after complete the whole sharpening process to prevent the motor from heating up.
Now check whether you have achieved your desired sharpness. Keep a tomato handy to check how sharp the knife is.

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

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.
