What About the Cheapies? Our Best Products Under $X

Electric knife sharpeners that are extremely cheap can be a little hit or miss. If you’re looking for a cheapie, you probably want to make sure your knives aren’t valuable. However, these three are quite cheap and may be worth looking at.

#1 Best Under $30: Smith’s 50005

#3 Best Under $15: Sruier

If you’re looking for the cheapest electric knife sharpener, we believe that this is it. It claims to be professional-grade and the price is tempting. However, it does have mixed reviews, with many saying that it’s junk. Of course, for that price, you may get lucky. It is one of those electric sharpeners that you may find on Wish, but sometimes, Wish can work just as well.

Are these really better than… regular knife sharpeners??

If you’re looking for a knife sharpener, your two choices are manual and electric. Think of it like pencil sharpeners. Some people say that electric is the way to go, as it helps automate the process and gives you that perfect cut. Others say that the electric sharpener can damage your blade and that it doesn’t give you that precise cut. When you see a heated debate, you may be on the fence about which one is the best. So let’s compare.


A manual knife sharpener has a few advantages over the electric. First, the price. If you see an electric sharpener for ten bucks, run away. Meanwhile, a manual knife sharpener for ten bucks can work just fine.

The manual knife sharpener is also much smaller and easier for you to store. If you live in an extremely small space, you may be better off with a manual. With that said, there are more compact electric sharpeners as well.

One of the advantages of a manual is that you’re in control. For some people, it’s more of an emotional reason. They like being able to feel the knife sharpening and like doing it with their own hands. For others, there is more of a logical reason. An electric knife sharpener can be quite aggressive, and it can damage your blade if you’re not careful. While reading the manual and practicing can prevent that, some people don’t like the hassle and they just go with a manual.

Finally, a manual is also better for a touch-up. If you need to rework your knife from the ground up, an electric knife sharpener may be good. However, for a small job, go with a manual.


Now, let’s make the case for the electric knife sharpener. After all, this is an article about electric knife sharpeners. These are becoming more popular, especially in recent years, as they become more advanced. They require less effort, giving you the ability to sharpen your knife quickly and easily.

Many electric knife sharpeners are preset, which means they will guide your knife and sharpen it at the perfect angle. There is no guesswork or calculating for you to do. Just put it in the sharpener and let the knife do the rest.

Finally, the electric knife sharpener is good for all types of knives. American, Asian, serrated blades, and any other type can be sharpened to perfection. You don’t have to relearn how to sharpen a knife if you get a new one. The sharpening process is so easy.

In addition, the electric knife sharpener is always improving. Their reputation as being blade damaging machines was true a while ago, but with modern knife sharpeners, the sharpening process is done to a T, and you don’t have to worry about the sharpener ruining your knives forever.

So both have their pros and cons. Since manual knife sharpeners are quite cheap, we say to buy a manual in addition to the electric. This way, you can have the best of both worlds. But to answer your question, we say that yes, most of the time, the electric sharpener is better, especially if you get a higher-priced one with more features and control.

Do electric knife sharpeners wear out?

Any electric device is going to wear out with time. However, most knife sharpeners are built to last for years. When selecting the best electric knife sharpeners, always make sure they have a good warranty. It should be for a few years. Besides, by the time your old electric sharpener has kicked the bucket, there will be a new one that is even better than the original.

It should be mentioned that the diamond abrasives in brands such as Chef’s Choice are built to last a long time, and you should be able to get a replacement should you need one.

How do you use an electric knife sharpener?

With any sharpener, two stage or otherwise, you should always read the manual. While electric sharpeners have a similar design, some of them have differences, and if you don’t read the manual, you may risk damaging your blade. With that said, here’s a general guide on how to do it.

Stick the blade in the sharpener’s slot. You should read the manual and make sure that the slot is appropriate for how you want to sharpen the knife. For the knife’s heel, press it down as far as you can so it touches the grinding stone. Through its tip, pull as slow as possible. As for the sharpening angle, it should be at a 15-20 degree angle.

The knife sharpener should set the sharpening angle for you automatically as you pass the blade. Pass it twice, and no more. Electric knife sharpeners only need a couple passes. After you’re done, move to the next stage and pass it again.

When you are done, rinse and let the knife dry. Most electric knife sharpeners use a magnet to collect any shavings left over, but it is a smart move to clean it off regardless.

But as we said, always read the manual. Too many people don’t read the manual and then give the sharpener a 1-star review because it ruined their knives. Don’t be that person.

Are electric knife sharpeners any good?

With an electric knife product, it depends. The cheap sharpeners are hit or miss, while the mid-range to expensive are good. With any electric device, every generation improves the machine, making it even better. The electric sharpener has been around since at least the 1950s, with old units being bulky and not having that precise sharpening angle that later ones have.

In order to find out if a sharpener is any good, your best bet is to read the reviews. They should give you some insight into the pros and cons of the electric sharpener. Read all sides before you make your purchase, and then you should have an electric sharpener for your needs.

Verdict: Your Best Electric Knife Sharpener 

And there you have it. We looked through many sharpeners and these were the ones that made the cut. Get it? Okay, bad jokes aside, let’s summarize the top five for those who need a refresher, or for those who skipped to the end. (Don’t feel bad, we all have done this.)

First, we have the Presto 08810. For us, this is the perfectly balanced sharpener for those who want a mix between value and quality. It can sharpen most knives quite well and it’s versatile in what it does. While there are more advanced out there, if you’re looking for a decent sharpening device, we feel this one is a good starting point.

Second, there’s the Chef’s Choice 15 Trizor XV. This one has the most features and gives you the most precise cut. It has that perfect sharpening angle that’s perfect for American, Asian, or serrated knives or serrated blades. It’s the perfect one, but it’s quite expensive. As a reminder, there is a two stage version that is a third less than the original.

Third, we have the Work Sharp. This is good if you have a workbench and you need a sharpening machine for knives or any other tool. It gives you the most control and is made for the biggest variety of tools. However, this one is not meant for the kitchen, so it’s for a particular niche. It can sharpen kitchen knives, but it may be too bulky and look odd for your kitchen. If you have a workbench, check it out.

Fourth, there’s the Edgekeeper. This is a budget knife sharpener. While it doesn’t have the most features, it’s competent at what it does. If you have normal kitchen knives, it will sharpen them well enough. There isn’t much to say about it other than it has the edge on other sharpening tools for that price.

And finally, we have the Chef’s Choice 250. This is a cheaper version of the Trizor XV. It has diamond blades and is good for serrated knives or serrated blades. While the Trizor XV is better, this one is good if you want that happy medium.

There we go. These babies will sharpen your knives. With sharpener tools that are electric, the sharpening process is made easier. With that said, always follow the manual and read up on the electric knife sharpening process before you buy it. Make sure you know about 20 degree angles, how to handle serrated knives, and everything else that goes along in the knife sharpening process.

Anyway, check out these electric sharpeners and see if there is one that works the best for your knives. We hope you end up having knives that have more edge to them than that poetry you used to write as a teen. Anyway, goodbye for now.
