When we tested this knife sharpener, we found that it takes about 30 minutes to sharpen a blade.

The only downside to this electric knife sharpener is that there is no power cord included. You must use either a USB cable or AC adapter to run it.

Unfortunately, we found that the unit itself is quite small when we tested this sharpener. While you can still comfortably hold it in your hands, it might be difficult to maneuver around your workspace.

While we didn't experience any major issues with the sharpener, we do recommend taking extra care when handling it. As mentioned earlier, it is fairly lightweight, so you may accidentally drop it if you aren't careful.

When we tested this sharpener, we found that it worked well for both straight edge and serrated blades. However, we did notice that it took longer than many of the other units to sharpen each blade. 

We were also disappointed with how loud the sharpener was, especially considering that it is meant to be used indoors.

Overall, we were pleased with the performance of this sharpener. It performed well and was relatively easy to use. However, we would prefer more options, such as a finer setting or one that could accommodate larger blades.

Pros

Cons

  • Takes Longer Than Most Units: While most sharpeners will take less than 10 minutes to complete, this sharpener takes about 20 minutes to sharpen a single blade.

Buyer’s Guide

Now that we've introduced you to an impressive range of knife sharpeners, it's time to give you a crash course on the things you should be looking for in your next purchase.

The right electric sharpener can last you years and give you plenty of use out of your knives, so making the right choice is imperative.

Not sure where to start? Stick with us and take a read through our buyer's guide for more useful information. 

Sharper Than A Serrated Blade?

Before buying any sharpener, make sure you understand the difference between a serrated blade and a straight-edged one. If you're not familiar with these terms, here's a quick refresher:

A straight-edge blade is simply a knife that has no serrations. They’re typically made from carbon steel and are often used for carving meats or vegetables.

A serrated blade has teeth cut into its surface, usually made from stainless steel and are designed to help you slice through foods like bread and cheese.

While there are pros and cons to both types of blades, they have very distinct uses. For example, if you want to carve meat, you'll probably want to go with a straight-edge blade.

But if you're planning on cutting up fruits and veggies, then a serrated blade might be better suited for the job. 

Once you know what knives you want to use or do use the most, you'll need to choose an electric sharpener that's up to the job.

What To Look For In An Electric Knife Sharpener

When shopping around for an electric knife sharpener, you'll find that there are several different features to consider. Here are some of the most important ones:

Size

Sharpening tools come in all shapes and sizes. Some are small enough to fit inside your kitchen drawer, while others are large enough to sit on top of your countertop.

The size of the unit will depend on how much space you have available.

Weight

When choosing an electric knife sharpener over a manual one, weight plays a big role. Manual sharpeners tend to weigh a tonne or two, which means you'll likely struggle to move them around.

Electric sharpeners are lighter, meaning you won't have as many problems moving them around.

Power Source

You'll also want to pay attention to the unit's power source. Many units require AC power, but those that don't are generally smaller and easier to transport.

Blade Support

Some sharpeners only support flat blades, while others can handle both flat and curved blades.

This feature is especially helpful if you own multiple knives with different blade profiles.

Warranty

Finally, you'll want to look at the warranty offered by the manufacturer. Most manufacturers offer lifetime warranties on their products, while others offer shorter warranties.

Keep in mind that this isn't always the case, however, so shop carefully before buying.

Frequently Asked Questions

Are Knife Sharpeners Bad For Knives?

No, knife sharpeners aren't inherently dangerous. In fact, they can actually improve the lifespan of your knives.

Knife sharpeners work by removing the dull edges of the blade, allowing the metal underneath to become sharper. The problem arises when people try to sharpen their knives too aggressively.

Overly aggressive sharpening can cause damage to the blade itself, making it less durable and more prone to breaking.

Do Knife Sharpeners Get Dull?

Yes, they do. That being said, most sharpeners include a mechanism that automatically adjusts the angle of the blade after each pass. This allows you to keep the sharpness of your blades consistent throughout the lifespan of the product. 

How Long Do Electric Sharpeners Last?

Most sharpeners should last between five and ten years. However, the quality of the sharpener will determine its longevity. However, if you buy a cheap model, it may not last as long as a high-quality product.
