3 Work Sharp WSKTS-W

Work Sharp WSKTS-W

4 Chef’s Choice Hone Hybrid Sharpener

Chef’s Choice Hone Hybrid Sharpener

Why is it Our Hybrid Choice?

This product came with a 3-stage hybrid technology that allowed us to use it both manually and with electricity. Its performance was also as we had expected – very sharp and polished edge every time we used any type of knife. Chef’s Choice always makes quality products, which was no different in this case as well.

The only thing we didn’t like about this knife sharpener was that it was a bit on the noisy side. Other than that, we were happy with its overall performance and you can also try for home use.

Detailed review

The chef’s choice hybrid is a knife grinder with an actual difference to offer contemporary means of electric grinding to the older means known as the manual method. This inbuilt technology incorporates 20 degree blades, and it can be used for any knives in that range. For 15 degree blades, you can use Chef’s Choice 1520.

The first two phases use power to whet the blade, while the third phase uses a hone covered in pure fine diamond particles to cut the knife to your taste. It also gives the edge that “v” shape. Since the third stage is manual, it can be used anytime and anywhere without power. Phase 3 also sharpens serrated edges.

It weighs approximately 2.65 pounds and measures 11.2 x 6.2 x 5.2 inches by length, width and height respectively. Guaranteed with a one-year limited warranty, it can last even longer if effectively and adequately managed.

Usability is very high as it includes a manual stage, which can be used anytime despite a power outage. You can use your chef’s knife effectively after honing it.

Key Points

  • 3-stage honing system
  • Razor-sharp edges with advanced hybrid technology
  • 100% diamond abrasives in the first two stages
  • An ultra-thin abrasive in phase 3
  • Phase 1 and 2 electric and manual honing in step 3


  • Can be used to whet a wide range of knives including straight edge and serrated knives, kitchen and household knives
  • Produces a razor-sharp arch-shaped professional edge stronger and more reliable than conventional V-shaped or hollow ground edges
  • The third stage can be used without power, allowing it to be used in the absence of power supply


  • Can only be used with 20-degree class knives
  • Not as durable as other models we discussed

Our Verdict

A razor-sharp edge with advanced 3-stage hybrid technology ensures a fast, easy and durable whetting of your knives.

Apart from the usability, it is a cheap option, making it well recommended for those with a lower budget under $50.

If you are not able to cover the power expenses, then the manual stage serves as an alternative.

Best Electric Knife Sharpener Reviews [Buying Guide]

1. Abrasive material

Grits provide the measurement of abrasiveness, and you want to make sure you find the perfect abrasiveness for your type of knives. We recommend a diamond tip with about 1000 grit. If your electric model is too gritty, this will damage your knife and if it is too smooth, it will not work on your knife properly.

So, find a balance between the abrasiveness and the knives you want to whet. That is the only way to get better results.

2. Sharpening stages

The best electric knife sharpener should have multiple whetting stages. Most of them have a minimum of two and a maximum of four. The different stages come with varying levels of abrasiveness. This means you can pick the stage you want in agreement to how blunt your knife is.

This will allow you to touch up your knife without going for a full-blown whetting that might actually damage it. Sometimes all a knife needs is a touch-up only.

3. Angle guide

An angle guide will let you know how to position your knife to get the optimum level of sharpening. It ranges from 15-30 degrees. The higher the range of degrees the more blades, different in shapes and sizes you can sharpen.

If it does not come with one, you might have to ruin a few knives before getting the perfect angle. And if the electric sharpener has just one-degree angle capacity it will restrict you to only being able to grind a few knives. We recommend that you get one with a range of angle guides.

4. Versatility

Is it versatile? In the sense that, how many different kinds of knives the electric sharpener can handle. Because the more it can handle, the better for basically everyone. If you are the type that uses different blades, you should get a versatile model.

5. Portability

The portability has to do with how much space you have in your kitchen, if the electric knife sharpener is massive, and if you want to travel with it. Some weigh as little as one pound and are handheld, while others can weigh as much as seven pounds and are not handheld. If you want to be able to move around with your honing device, then go for a portable model.

6. Safety

When looking for the best electric kitchen knife sharpener you want something safe for the kitchen, easy to use with little or no danger hazard. And some can be a danger hazard, probably because of their design. So it’s imperative to get a safe one. By checking the model and how it works.

7. Cleaning ease

The design of some electric models makes it hazardous and hard to clean, so you want to choose one that has a friendly design allowing easy cleaning. An easy to clean model has an open configuration and you do not have to dismantle it to clean. Aim for those ones, and leave your cleaning issues behind you. Unlike battery operated knife sharpeners, electric ones are stronger and easier to use.

8. Range of angles

These devices come with a different range of angles allowing you to sharpen different knives of different shapes. More angles mean more variety of knives. Some have just one and others have all. Pick the range according to your specifications and preference. This is suitable for someone who uses a variety of knives.

9. Speed

The speed of an electric knife sharpener determines how fast or slow your cutter will be whetted, so if you want just to touch up the knife go for a slower model. But, a faster speeding one will grind really quickly. Or you can get one with different speeds.

10. Longevity

Some models are more durable than others due to the building material of the knife edge, which can be diamond or other metals. Please note that diamond edges are known to last longer.

11. Noise

Knife sharpeners can be noisy in general, what you can do is settle for a less noisy one. The seller might try to beguile you by telling you the noise is not loud, if you can turn it on and hear it for yourself.

12. Warranty

Not all models come with a warranty. You want to keep an eye out for a warranted model so that you can return when it develops any fault during the given warranty period.

Why Use an Electric Knife Sharpener

An electric knife sharpener is a machine powered by electricity that is used for whetting knives. Most of the good ones come with two or three abrasives; so you can pick one of your choices. It also comes with different angles allowing you to bend your knife and achieve maximum sharpness.

The importance of these electric devices cannot be undermined, whether you use it for your personal kitchen or you are a chef. They can add a lot of convenience to your daily life. They are safer than traditional non-electric mechanical sharpeners.

Some models can work on serrated knives, while other models cannot. In this review, we will provide you with all the necessary details to make your hunt for knife sharpeners a bliss.

Electric Knife Sharpener: What to Consider?

You need to ask yourself the following questions before you begin your quest.

  • What kind of knives do you have?

Electric sharpeners are made mainly to handle smooth-edged knives, and only a few can whet a serrated knife. And if you use one meant for the other you can damage your blade, sometimes beyond repair. Finding the answer to this question will help you choose a suitable solution for your knives.

  • How much space can you spare?

The design of electric models is much bigger than the manual knife sharpeners. And as such cannot just fit into the kitchen drawer or cabinet. So, if you know your kitchen lack space, you might want to rethink buying one. And get the most suitable size to suit your kitchen space.

  • How patient are you?

If you are the type with some patience, you would not have any problem buying a manual sharpener. But if you are not patient, then go electric as they are always faster and easier to use. So, if you are the type that is always on the go then this is for you, as it is easy to master and use.

  • How much do you value your knives?

Asking yourself this question is essential, because most electric sharpeners can overdo the job and even chip off the edges of your knife, and this can destroy them.

  • Does noise bother you?

If it was easy for you to answer yes to this question, then do not be in haste to get an electric option. As most of them are loud and noisy and most people cannot stand it.

  • Are you left-handed?

Most of the electric sharpeners in the market are made for right-handed people, though they can be used by left-handed people. So, do consider this before you order one.

How to Use Your Electric Knife Effectively?

Now that you know about the available knife sharpeners, you should use these tips to understand how you can use it so as to serve you well for a long time. Frequent uses of your knife without honing contribute to its becoming dangerous over time, leaving you with a dull knife eventually. In order to maintain its edges, you should know how to use the device. Before you hone your knife, make sure the knife blade fits entirely through the device for optimum results

There is the presence of two to three grinding wheels on the electric sharpener, all with different coarseness and grit making it a useful knife honing tool. To sharpen your knife, these are the steps you should take:

  • Make sure the heel of the knife connects with the grinding stone by pressing it down as far as possible. Work your way up to the tip of the knife.
  • Make sure the blade is at an angle of between 15o -20o. The sharpener then does the job of setting the knife-handle’s angle to connect with the grinding stone
  • The blade should be passed only twice slowly to affect the task of sharpening the knife
  • The process should be repeated on the more exceptional stone and do as you have done above
  • Make sure you rinse your razor and dry it with a clean cloth

  • It can completely damage a blade if used on an abrasive that is not meant for it.

Care & Maintenance

  • Cleaning these machines is very essential though it should not be done frequently. As water or fluids can cause rust and spoil it, you should clean it once a year to prevent it from getting damaged gradually. This means you have a longer time to spend with your new honing device.
  • Store the device in a cool and dry place. Most people keep it in their kitchen and in all honesty, a kitchen is hardly a cool or a dry place. The point is humidity and fluids affect the electric knife sharpener negatively. So keep it away from areas that have those.
  • Also, make sure the blade you are about to hone is clean and it does not transfer any food particles to the electric knife sharpener that will cause damage.
  • Avoid cutting acidic fruits near it as it can cause corrosion in the blade.

2. How does an electric knife sharpener work?

Ans. Electric knife sharpeners have different stages or slots, each with its own function. The coarse slot is used for sharpening dull or damaged knives, while the fine slot is used for honing and polishing the blade.

Some also have a slot for serrated knives. Remember to avoid applying too much pressure on the blade because this can damage it.

3. What do professionals use to sharpen knives?

Ans. Professional chefs or cooks usually prefer the traditional methods like whetstone because this gives them more control over the process for precision.

Ans. They are there to protect your knife and keep it functioning, not ruin it. But the wrong sharpening method or tool can potentially damage the blade.

A coarse grit stone or sharpening at the wrong angle can also cause the blade to lose it’s temper.

5. How often should I use my electric knife sharpener?

Ans. The frequency depends on how often you use your knives and how dull they become with use. We recommended that you sharpen your knives with an electric sharpener every three to six months or whenever they start to become dull.
