The third phase is the finishing step. It gives the knife a smooth finish by smoothening and polishing it with the 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. It can sharpen any 20-degree knife or any 15-degree knife to a fifteen-degree edge. The Trizor can sharpen most knives.

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 has an on/off switch, and comes with a 3-year limited guarantee.

Provided you were impressed with all the features of the Chef’s Knife – but want a model which could sharpen other tools as well – this knife and tool sharpener might be just what you need.


This model is the best, and it has a lot of versatility. It can sharpen straight and curved blades. What’s more, it could even handle blades with unconventional shapes.

Moreover, the ability to adjust the speed of your motor is a bonus. If you need to remove rusty or damaged blade material, increase the speed. If you just want to hone your knife’s edge, turn up the motor.

Another notable feature is the model’s ability to change its sharpening angle. It does this by turning the dial on its control panel. You can sharpen serrated knives, kitchen, fillet, and pocket knives. Simply adjust the angle with the dial.

  • Sharpen knives and tools
  • Variable motor speed
  • It has a dial to adjust the sharpening angle

The Edge Keeper is slimmer than the model that was previously reviewed. 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 for this tool looks like a double-edged blade. It has the most tools with the recommended angles of 15 degrees at one end. On The other is that it reduces its effectiveness when dealing with blades 20 degrees in angle.

On The flip side is that it automatically positions your blades to eliminate any guesswork. A unique internal magnet is included that collects all shavings and makes the tool neat and tidy. Rubber feet add stability to the model.

This sharpener cannot be used to sharpen thicker edges. That is, because, its sharpening angle isn’t made for serrated or ceramic knives.


  • 2-stage sharpening
  • Positions blade automatically
  • Internal magnet suckers in shavings
  • Sharpening wheels come diamond-coated


  • Not recommended for use with ceramic or serrated knives

Final Verdict

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.

The E5 has replaced the Edge Keeper’s fixed abrasive with a flexible, abrasive-based belt. The E5 is worth the investment. Let’s find out.

One dilemma which is common with other sharpeners – and which you won’t encounter with the E5 – is deciding when to stop. The E5 has an auto-shutoff feature that will turn off the model when the knife has been sharpened to the desired 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 traps all debris in order to keep your counter and sharpener free of any debris.

Lastly, we finish our review of the E5 by discussing two highly-useful features – the first of which is its ceramic honing rod. It gives you that extra touch of polish with its polished sharpener.

You have then the Micro Forge port You can condition your knife to cut through both hard and soft material by running it through.


  • Flexible abrasive belt
  • Angle Guide available
  • Built-in vacuum to collect debris
  • Auto-shutoff feature


  • Preset angle is 17 degrees

Final Verdict

The Work Sharp Culinary E5 costs a lot, but it is not cheap. Though there is nothing in its price tag which the abovementioned features won’t be able to justify with ease.


5. Presto 0 EverSharp Electric Knife Sharpener – America’s Test Kitchen

Presto 0 EverSharp Electric Knife Sharpener 1, Black

View at Amazon

Presto is the household name for electric knife sharpeners, with all due respect to the other brands mentioned in this review.


The Ever Sharp’s simplicity is what we love most. It uses a two-step process. The first involves the grinding of your knife to remove any hard rust. The second step is to sharpen the blade by passing it 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. Sapphirite, which gears the sharpening wheel, gives it an extra special touch. Thanks to it, you get a slight micro-serration on the blade’s edge, which gives it a super-sharp edge.

You also get three sharpening angles with the package, thanks to its interchangeable blade guides. You can also choose from thin, thick, or medium blades with the slider.

That means you can use that regardless of their thickness, all metal knives – from the cleavers to chef’s – are usable with this model. This model cannot be used for ceramic knives.


  • Super-sharp edge
  • It’s easy to use
  • Slider offers three blade options
  • Interchangeable blade guides


  • Can’t sharpen ceramic knives

Final Verdict

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.


6. Chef’sChoice 250 Diamond Hone Hybrid Sharpener Combines Electric and Manual Sharpening – America’s Test Kitchen

Chef’sChoice 250 Diamond Hone Hybrid Sharpener Combines Electric and Manual Sharpening for Straight and Serrated 20-degree Knives Uses Diamond Abrasives for Sharp Durable Edges, 3-Stage, White

View at Amazon

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. To perfect your knife, the third stage will require manual operation.

You can also sharpen and hone the edges with ultra-thin diamonds abrasives. This model could also be used to create jagged blades. This model can be used to re-sharpen knives for hunting, sports, kitchen, and pocket.

We must now turn our attention to the sharpening angle. The 250 Diamond will 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.


  • Triple-bevel edge
  • Can you hone without electricity?
  • Ultra-fine diamond abrasives


  • Not compatible with knives of 15-degree classes

Final Verdict

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.

Sharpener Materials

Visit the market, and you’d come across four types of sharpeners: carbides, steel, diamond flecks, and ceramic. Diamond flecks are the best – since they cause less friction and provide a gentler, softer sharpening process. They are less likely than other flecks to damage the blades.

Carbides, meanwhile, while not as good as diamond flecks – are certainly not as expensive. That means if you can’t afford to pay over the odds, go for carbide. As for steel and ceramic, they aren’t any good for sharpening. Instead, their utility lies in honing – which is the process of cleaning up the blade’s edge.

Sharpening Angle

There are generally two types of knife: the 20-degree European model and the 15-degree Asian one. No matter what sharpener you choose to use, ensure it can sharpen both of these angles.

However, if you’re unsure about the angle of your knife, you might go for an adjustable knife sharpener. This allows you to adjust your knife’s angle to maximize its utility, as the name suggests.


In contrast to what most people believe, sharpeners aren’t only good for refining the blade. Provided you can afford to spend a bit extra, you can get yourselves a multi-stage sharpener – one which could hone and sharpen at the same time.

If you want a knife that offers precision grinding, coarse grind, and polishing all at once, a three-stage sharpener will be your best choice. Lastly, if all you want is compactness – and a sharpener which is a cinch to use – you’d do well with a one-stage process.

Multiple Slots

You might be able to guess that not all knives are the same blunt. This means that some knives might need less grinding than others. Multiple slots in your sharpener are what you will need. It allows each knife to have a unique cutting tool by providing different slots.

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.
