The LINKYO Electric Sharpening System can make any dull knife sharp like a dream again.
Although it is commonly compared to the Presto 08800 because of a similar design and the two-stage sharpening construction, I find some useful details that make this model worth a try.
Such as the removable plugs and mess-free receptacles that help cleanup to be easier with no mess. Or, the non-slip suction cup feet to keep the unit stay in place while sharpening and I do appreciate this add-on. Thanks to it, you’re kept away from any potential danger during use.
The sharpening performance is amazing as well.
It can sharpen a dozen knives in a row with consistent results with no hesitation to spin or being shut off.

This America’s test kitchen sharpener gives a nice upgrade from the 20-degree angle to the 15 within a minute for the first time sharpening and under 10 seconds to re-sharpen.
That means you can have a bunch of knives sharp like razors without spending hours of life. For such incredible performance, it’s a big thank you to the clever combination of the ultra-sharp 15-degree XV technology and the durable Trizor edge.
Another bang-for-buck feature is the 3-stage EdgeSelect sharpening system therein stage 3 – by using a patented flexible system – is to polish serrated blade edges better.
All-in-all, this is an expensive investment but its decent versatility makes it worth it.

Chef’s Choice 320 Electric Knife Sharpeners
Differing from the previous Chef’s Choice sibling, the sharpening system of this version just includes 2 stages and the first stage is less aggressive than the 3-stage.
This gives you one less worry about cutting too much meat off the blades during the use. So if you’re a beginner, this is definitely a good start. The lighter and smaller silhouette also makes it easier to control.
Take note that this unit sharpens bladed tools at 20 degrees and even works on serrated knives.
The biggest selling point is it creates a phenomenally polished blade edge with quick, foolproof results. All thanks to the patented flex stropping disks in the second stage.

Presto 08810 Electric Knife Sharpeners
Presto 08810 Professional Electric Knife Sharpener is a great option for people who don’t have plenty of time on their hands.
The adjustable blade guides and 3-stage sharpening system makes it ideal for sharpening axes or badly damaged knives and tools.
Compared to the Presto’s 2-stage electric sharpener, stage 1 of this version gives a very aggressive power, which means it could take lots of meat off the blade if you’re not careful. Besides, the tool itself is heavier and larger than its previous sibling.
In turn, it allows for better positioning of the blade to the sharpening wheels. The adjustable blade guides are perfect for thicker bladed tools.
That’s why I would recommend this for heavy-duty use, like workshops, garage bladed tools, axes, and things like that.

Chef’s Choice 270 Hybrid Hone Knife Sharpener has a triple bevel arch-shaped edge that features 3 separate bevels at different angles on both sides of a blade edge. Compared to the 250 which has a double bevel edge, this new version lasts much longer.
This knife sharpener works great on sharpening all types of 20-degree blades or re-sharpening from 15-degree to 20.
It is fast and efficient while doing a fantastic job that I think is very close to a manual stone sharpness.
The 1st stage is aggressive enough to get rid of enough material to remove nicks but after the 2nd and 3rd, the blade is smoothly honed and polished, leaving a hairsplitting sharp edge.

The Ultimate Guide To Choosing Best Electric Knife Sharpener In 2020
Sharpening type – belt or wheel
There are two common types of sharpening knives – using rotating wheels and using a belt grinder.
The belt sharpening type includes some belts with different grits to train a knife. During the use, you have to swap belts to sharpen and hone it.
The wheel sharpening method, or called multi-stage sharpeners, sharpens a knife through several stages (commonly 2 or 3 stages). In each stage, it utilizes a specific rotating wheel that differs in grits and abrasives.
To sharpen, re-sharpen, or polish a blade, you just need to pass it through all the stages.
In comparison, the belt sharpener gives you better control over the grits, from coarse grinding to polishing and honing. And this method is cheaper in the long run. Meanwhile, the wheel sharpener is much easier to use – ideal for beginners.
This feature depends on the types of knives needed sharpening and it is paramount.
Choosing an improper sharpening angle for your knives will consequence to decrease its durability or inefficient performance. For those who don’t know, different types of knives come in a specific bevel angle.
For example, the Japanese knives are sharpened at a bevel angle of 15 degrees while the European models are at 20.
If you own different types of knives, look for a sharpener with adjustable bevel angles.
Your knife sharpener will never sit in the kitchen countertop forever, which means you should look for a portable and compact model.
Think backyard, garden, or garage.
Even the area of your kitchen countertop, what if it’s too narrow for a bulky knife sharpener?
One thing to take note is the more stages the sharpener features, the heavier and bulkier it will be.
