The Buyer’s Guide for Best Electric Knife Sharpeners

chef Sharping knife

If you have bought yourself a sharpening knife, then you also need an electric knife sharpener, right? This specific purchase of yours requires some technical information that we have gathered to take you through.

We will break down all the technicalities linked to buying an electric knife sharpener so that when you do end up with it, you will know exactly how to use it and deal with it efficiently.

What is a sharpening angle?

If you have been hunting for a knife sharpener for a while now, then we are sure you must have come across this term. This term simply means that every knife has a specific angle on which the knife’s cutting edge has been manufactured. The sharpening angles determine the durability and sharpness of your blade.

You must sharpen your knife at the same angle that is of your knife’s edge. Every knife comes at a different sharpening angle, and the sharpening process can be performed differently.

We know how this must have sounded very complicated, which is why we suggest you go for a knife sharpener that features sharpening guides. This way, you won’t have to determine anything yourself, and the sharpener will itself take care of everything.

Things to consider before buying an electric knife sharpener!

Since there are a lot of technicalities involved in buying an electric knife sharpener, you must take a look at all the points we have mentioned below before you go ahead and choose a knife sharpener,

  • Stages of the sharpening process

Most of the electric sharpeners you see on the market come with two or three slots, and all these slots determine a different stage of the knife sharpening process. The more steps you have, the more complicated the entire process is going to be.

These slots also determine the size of the machine and the precision of sharpened knives. We usually recommend going to a three-stage electric sharpener that performs precision grinding, coarse grinding, and polishing.

However, if you are looking for an easy-to-use sharpener, then a two-stage unit will do the trick.

  • Angle guide

The sharpening angle is what we have just previously discussed, and as you must have seen, you have to choose one for your knives. If you are an expert, you won’t have any trouble guessing your blades’ angle, so you can easily opt for a simple sharpener.

However, this isn’t the case for most people, so we recommend either going for an angle guide so that it will guide your knife’s blade to precision without much hassle.

  • Design and construction

For the most part, the design doesn’t hold a lot of concern for people who want to sharpen their knives’ edges. What matters is the construction and durability.

You need a well-constructed and durable electric sharpener to do the job in the most efficient way possible. Look for something durable with stainless steel and sturdy construction quality. Also, make sure the device doesn’t shake or get unstable while you’re sharpening your knives. That would make a big mess out of your simple task.

  • Warranty

Also, another thing to look for is a warranty. This will protect your money, and the knife sharpener itself in case it breaks. Most of the high-quality sharpeners in the market come with a lifetime warranty because the brands are pretty confident their products will last a lifetime.

In case there isn’t a lifetime warranty, we would suggest that you look for other options.

Some common FAQs regarding electric knife sharpeners!

We are answering some commonly asked questions about electric knife sharpeners down below!

  • How long will it take to sharpen a knife?

If you keep your knife in good condition, it will hardly take 30-seconds for you to get the process done. But in case your blade is pretty abused, then it will take some time.

  • Are manual knife sharpeners better than electric knife sharpeners?

Sometimes yes! Manual knife sharpeners are far less complicated than electric knife sharpeners. They don’t have any technical specifications, plus you have complete control over the sharpener, so it’s less dangerous.

  • Are knife sharpeners dangerous to use?

Yes! Most of the knife sharpeners don’t come with enclosures, so the sharpening disc might hurt you if you aren’t wearing specific gloves. Make sure you handle these blades very carefully when you’re detaching them from the unit.


Doesn’t matter what final choice you make; the only thing you need to ensure is your comfort. When choosing a knife sharpener, the safest option is said to be the best option. Don’t go for something too tricky if you’re just buying your very first electric knife sharpener.
