How Can You Choose The Very Best Electric Knife Sharpener

So, without any further ado, here are the things you need to consider when shopping for the best electric knife sharpener:
There are a few types of knife sharpeners available on the market. The main difference is between the manual and electric knife sharpeners, but your mind is probably already set on electric ones since you are reading this text.
It is still good to know that both electric and manual knife sharpeners work with the same principles. They feature an abrasive surface; you should scrape against the metal edge of your knife blade to sharpen it.
When using a manual knife sharpener, you have to rely on the strength of your arms, but electric knife sharpeners feature spinning wheels that do the hard job for you. The abrasive is mounted on these wheels, and that increases the friction as you draw the knife through the sharpener making the sharpening process quicker and more effective.
2. Abrasive Material
There are different abrasive materials used for knife sharpening. They differ in the level of texture and grit level.
- A coarser grit level materials are best suited for rough surfaces and sharpening at high speed. They are used to restore a dull blade to an adequate level of sharpness.
- Finer grits, on the other hand, are much slower and remove less material from the blade.
These finer gritted abrasives are not intended for major sharpening tasks but rather to fine-tune your blade edge and make it the sharpest it can be. Therefore, you should use them in the final stage of the sharpening process to polish the knife edge and make it smooth.
What Abrasive Materials Are Used For Electric Knife Sharpener Wheels?
- Most electric knife sharpeners feature either a diamond abrasive or a Sapphirite sharpening wheel.
- Diamonds might be the girl’s best friends, but when it comes to knife sharpening, they do a man’s work. Being made of the hardest material, diamond abrasives are best utilized for coarse grinding. They are not the best option for precision grinding as they can damage the delicate blade edge.
- Sapphire abrasives do the same job but are less aggressive and still perform the job well than diamond ones.
3. Abrasive Belt
The very best electric knife sharpeners should have abrasive belts. An abrasive belt will provide you with tons of flexibility and an opportunity to sharpen all sorts of blades. Therefore, you will not be limited to straight knife blades only.
4. Sharpening Stages
A majority of electric knife sharpeners feature either two stages or three stages. What are the sharpening stages?
The number of sharpening stages actually represents the number of slots you have available to sharpen or polish your knife blade.
Three-stage sharpeners most often offer you the possibility for coarse sharpening, honing, and polishing. Thy thus guarantees the utmost precision.
Honing is the process of straightening the bent or misaligned blade edge. It should be done more often than sharpening; for the best results, you can hone your knife before each use and after every washing.
Two-stage sharpeners are less complicated to use but do not provide as much precision as the three-stage ones. Home users will do just fine with a two-stage sharpener while professional users have to go for the three-stage sharpeners.
5. Angle Guides
Knives can be used for different purposes. You should sharpen the blade to a certain angle, depending on what you plan to use it for.
Most electric knife sharpeners can sharpen your blades only to a 20-degree angle or a few specific angles. A 20-degree angle is the most common angle for American-style kitchen knives.
In fact, the majority of kitchen knife blades require to be sharpened at an angle between 15 degrees and 25 degrees, and that means you can manage with any basic electric knife sharpener.
If you want a sharpener that can offer you more angles than this, you should buy a manual sharpening stone. When using a sharpening stone, you have the freedom to adjust your angle by hand. It requires a lot more effort but enables you to fit the angle to whichever needs you may have for each blade.
Most electric knife sharpeners are designed to work with any straight-edged blade and all the regular kitchen knives. If you want to be able to sharpen curved or serrated blades, make sure that the electric knife sharpener you buy is up to that task. Be prepared to pay more, too, as only a few premium products are capable of sharpening all kinds of knives.
When Is the Ideal Time To Sharpen Your Knife?
How can you tell when the right time to sharpen your knife is?
You will definitely notice that a knife is less effective. Sometimes, it will be enough to hone it, but on some occasions, that will not be enough to improve the performance of your knife. If honing does not make a noticeable difference, it is high time to sharpen your knife blade.

- You can’t cut cleanly and quickly as usual.
