What’s the most important tool in your kitchen?

A knife.

However, whether you’ve purchased a good chef’s knife or acquired one from your local store, chances are that it will go blunt sooner or later. When that happens, your knife will slide off the food, thereby making cooking a dangerous process.

Hence the reason why you need the best electric knife sharpeners. Apart from taking the danger out of the picture, but electric knife sharpeners – by sharpening the blade – also make cutting easy

The 5 Best Electric Knife Sharpeners You Need To Buy

1. Chef’s Choice 15 Trizor XV

One of the best-selling knife sharpeners on Amazon – the Chef’s Choice is one of the best rated as well. To gauge whether or not it justifies its lofty reputation, let’s look at its features.

First things first, the Chef’s Choice has a three-stage sharpening process – with the first two stages using pure diamond abrasive to not only sharpen the blade but also create bevels on the knife for added durability.

As for the third phase, it gives the blade a smooth finish by gently smoothing and polishing the sharpened knife with its stropping material-plated slots. What’s more, all three stages have a flexible angle guide, which means you won’t have to resort to guesswork to estimate the sharpening angle.

What’s more, increasing the utility of this sharpener is this knife converter. Whether you have a 20-degree knife or 15-degree knife, it will sharpen both to a 15-degree edge. That means you can sharpen almost all types of knives with the Trizor.

Furthermore, in contrast to other electric sharpeners, the Trizor isn’t loud – with its noise ranging between the bearable limit of 65 dB and 75 dB. It also features a convenient on/off switch and comes with a 3-year limited warranty as well.

As a mere glance on its features would tell, the Chef’s Choice 15 Trizor XV has everything you might look for in a high-end knife sharpener.

2. Edge Keeper Electric Knife Sharpener

If the previously reviewed model was on the bulkier side, the Edge Keeper is as slim as they come. So you’d have no complaints about the dimensions of this model.

In case you were thinking, the compact dimensions of this model haven’t deprived it of utility. Instead, despite its slim shape, it boasts two-stage sharpening – the first of which removes out rusty material from the blade with the second leaving behind polished edges.

The pre-set sharpening angle of this tool comes across as a double-edged sword. Where on one end it provides most tools with the recommended 15-degree edges. On the other, it reduces its usefulness when dealing with 20-degree blades.

On the flip side, it automatically positions the blades to take the guesswork out of the equation. You also get a unique internal magnet which, by sucking in all the shavings, leaves the tool nice and tidy. Then there are the rubber feet which imparts added stability to the model.

Finishing on a low note, you cannot use this sharpener for thicker edges. That is, because, its sharpening angle isn’t made for serrated or ceramic knives.

Despite all its shortcomings – and it hasn’t got a lot of them – the Edge Keeper with its reduced price tag and high functionality is a must-have for most homes.

3. Work Sharp Culinary E5

Doing away with the fixed abrasive which we saw with the Edge Keeper, the E5 has instead opted for a flexible, abrasive belt. Does this unique design make the E5 worth-having? Let’s find out.

Starting with a glance at its design, the E5 uses a 17-degree angle guide with a rotating belt. In plain English, that means that its sharpening belt isn’t fixed but flexible. That means you can rely on it to sharpen almost any type of knife blade.

One dilemma which is common with other sharpeners – and which you won’t encounter with the E5 – is deciding when to stop. That is, because, it has a pre-programmed auto-shutoff feature which turns off the model once the knife is sharpened to the optimum level.

Furthermore, while the speed of this knife sharpener is also amazing – since it completes the whole process within 90 seconds – what we really like is its built-in vacuum. It sucks in all the debris to make sure that your counter (as well as the sharpener itself) remains free of debris.

Lastly, we finish our review of the E5 by discussing two highly-useful features – the first of which is its ceramic honing rod. By giving off a polished sharpener, it gives you that bit extra.

Then you have the Micro Forge port running through which you can condition the knife to easily cut through both soft and hard to cut.

Granted, the Work Sharp Culinary E5 is anything but cheap. Though there is nothing in its price tag which the above mentioned features won’t be able to justify with ease.

4. Presto 08800 Ever Sharp

With due respect to other brands mentioned in this review, Presto is a household name for making the best electric knife sharpeners.

Simplicity is one feature which we admire the most about the Ever Sharp. It has a two-step procedure; the first of which involves the grinding of the knife to remove hard rust. The second, meanwhile, hones the blade by letting you pass the blade through the two remaining slots.

Since you get all the slots in an angle, there is no need to guesstimate the blade’s sharpening angle. Giving it a touch of excellence is Sapphirite which gears the sharpening wheels. Thanks to it, you get a slight micro-serration on the blade’s edge, which gives it a super-sharp edge.

Furthermore, since it has interchangeable blade guides, you get three sharpening angles in the package. Then there is the slider which lets you choose between thin, thick or medium blades. That means you can use that regardless of their thickness, all metal knives – from the cleavers to chef’s – are usable with this model. Though you cannot use this model for ceramic knives.

For those of you who don’t have a ceramic knife in their kitchen, they shouldn’t have a second thought while purchasing the Presto 08800 Ever Sharp.

5. Chef’s Choice 250 Diamond

The second model from Chef’s Choice in this review, the 250 Diamond is visibly more advanced despite costing marginally more than its counterpart.

The Chef’s Choice 250 diamond relies on a 3-stage operation – the first two of which use electricity to remove rust and sharpening the knife. The third stage, meanwhile, requires manual operation from your side to hone your knife to perfection.

Moreover, since it has ultra-thin diamond abrasives, you can not only sharpen and hone both edges but could also get a jagged blade. The likes of hunting, kitchen, sports, butcher and pocket knives can be re-sharpened using this model.

Turning our attention to its sharpening angle, and the 250 Diamond can only work with 20-degree knives. While that is undoubtedly a shortcoming – since you cannot use 15-degree knives – the absence of 15-degree compatibility allows it to give more durable edges.

Still, if you have doubts about the performance of this model, the fact that it comes with a 1-year warranty – and is manufactured inside the US – should wash them away.

Though the lack of 15-degree compatibility is obviously a shortcoming, the Chef’s Choice 250 Diamond more than makes up for it with the added durability that it provides to 20-degree blades.


There you have them; six of the best electric knife sharpeners money can buy. From the ridiculously cheap to the astronomically expensive – and from sleek and compact to bulky and heavy-duty models – this article has everything you need. Now the onus is on you to make your decision and select what you think is the best electric knife sharpener for your needs.
