Electric Knife Sharpener Buyer's Guide

It's important to select the best electric knife sharpener that has everything you need for sharpening your kitchen or survival knives. Here are some key features to consider:

Warranty/Guarantee

When picking a knife sharpener model, you'll have some that include a warranty. These are sometimes comprehensive but usually limited. Make sure to find out exactly what the warranty covers. It's usually included in the fine print of the terms & conditions

A lifetime warranty is less likely, but this provides the best support possible and will make it easier to extend the unit's lifespan. It will also boost the cost but is arguably worth it.

You should also check how long the warranty is valid for. This figure is usually one year, although other models are valid for 2 or 3 years, for example.


Finally, there's the satisfaction guarantee. This is sometimes offered to provide you with a refund/exchange if you're not 100% happy with the electric knife sharpener. It's usually valid for 30 days.

Grinding Precision

It's important to pick a unit that produces an angled edge that's precise. This is critical to get your knives as sharp as possible.

Precision guides keep the blade at a precise angle to diamond abrasives. This is a key feature since it eliminates guesswork about which angle you should use during knife-sharpening sessions.

Price

The price of an electric knife sharpener can vary considerably and is based on several factors. That includes the brand, quality, features, versatility, and so on.

How much should you expect to spend? There are several quality units in the under-$100 price range, yet the old saying "you get what you pay for" generally applies. So if you spend $30 on a model, you shouldn't really expect many bells and whistles.

Efficiency

This is related to the amount of blade you and grind off. For example, some grinding wheels can grind chips a maximum of 1mm off ceramic blades.

Machines that are more effective at sharpening knives can also save you money. When a sharpener helps to keep the units as sharp as possible, this extends their lifespan. As a result, you'll just have to re-sharpen them instead of shelling out lots of money for a new set of knives.

Speed

This is a loaded issue. It's based on various mechanical-related issues. There's also the issue of first-time and re-sharpening, with the former taking much more time. When you need less time to sharpen knives, this will boost the efficiency of the process.

An X-factor is how many knives you'll need to sharpen. If it's for a home kitchen, then you'll have limited blades to sharpen. Meanwhile, a restaurant kitchen will have many knives to sharpen, so it's critical for the process to be as efficient as possible.

​Knife Guide Slot

Look for a universal type. This will allow you to keep the blade at a bevel angle or fixed angle. 

Sharpening Wheels

These are made of various hard materials, but one of the best ones is sapphirite, which is used by professional sharpening shops. This is one of the key components of a knife sharpener, so it's critical to learn about the material that's used for a particular model.

You should also look for removable wheel cartridge/cover. This makes the unit easier to clean, which is always a plus. Any machine with moving parts can be tough to clean so it's helpful when you can remove certain components.

Stropping/Polishing Discs

Here's another key feature to look for since it will help fine-tune the blades after the initial sharpening. These discs are used in either Stage 2 or 3 of sharpening.

Electric/Hybrid

These are the two main types in terms of the power source. The electric units are 100% electricity-powered. However, hybrid units include electricity and mechanical systems in the different sharpening stages.

Flexibility

You should learn what kind of knives a particular knife sharpener is compatible with. Some can only be used with serrated or straight-edge blades, and others can be used for both.

Then there's the material like stainless steel, carbon, or alloy. These are some of the main types of materials used to produce knife blades.

Another related issue is whether the unit can sharpen 15-degree Asian knives and 20-degree Euro/American knives. This will add more versatility based on the types of knives you currently own.

You should also find out whether the unit can be used for sharpening different knife types like kitchen, household, sport, and pocket. If one sharpener can be used for all them, it's more versatile


If you're looking for the most flexible units, then pick one that works with all knife brands and types. This will eliminate the need to purchase a different sharpener for different types of knives. That's definitely a situation you'll want to avoid.

Settings

The general ones are Coarse and Fine sharpening. However, there's some leeway with these settings including Ultra Coarse or Fine, for example. The wider range of settings the easier it will be to get the exact sharpening you want.

Manual

As with many other products sometimes electric knife sharpeners don't include a manual. However, they often do. Sometimes this just includes instructions for operating the knife sharpener. Other times it also includes tips/suggestions.

Most importantly the manual's instructions should be detailed and clear. These are usually the biggest complaints about such documents. Even if you've used an electric knife sharpener before different makes and models have different instructions.

Size/Weight

You probably shouldn't expect a knife sharpener to be as small as other small appliances. However, you can find some units that will easily fit on a countertop. This provides more functionality since it won't take up half your kitchen. It also means it will be easier to store.

Brand

You can find a wide range of manufacturers who make electric knife sharpeners. It's highly advisable to go with established brands like Chef'sChoice. This will help to ensure you have a better experience in terms of the product's quality, customer service, etc.

You should generally avoid off and generic brands. These companies tend to produce question marks with little or no online presence. As a result, there's a good chance you have problems with quality control, customer service, and shipping/exchanges.

Ease of Use
One of the most important features to look for is the guide system. This provides optimized control for precise sharpening. It provides the right sharpening angle in different situations and ends any guesswork.

Stages

When shopping for an electricity-powered knife sharpener, the main systems you'll find are 2 and 3-stage sharpening. The stages are sharpening, honing, and polishing. In the case of 2-stage sharpening, the latter two processes are basically combined.

Product FAQs

Here are some FAQs about electric knife sharpeners:

What materials are used to make sharpeners?

It depends on the particular model you select. Some common ones include nylon plastic, ABS plastic, tungsten carbide, and stainless steel. Make sure to look for a unit with quality materials and craftsmanship. This will boost the cost of the unit but is worthwhile if it also extends the lifespan.

What is honing?

This is fine sharpening or polishing that doesn't remove any metal from a knife blade. Honing/polishing should only be used for fine knives like those made with Damascus steel. These knives have a small bevel angle that coarse sharpening could alter

How long do sharpeners last?

This varies based on different factors including quality, and frequency/type of usage. If you purchase a quality knife sharpener, it will likely last 5+ years. It greatly depends on the overall quality of a particular unit.

How often should knives be sharpened?

You should hone knives often, and it's best to do it daily. It doesn't remove any metal and extends the blade's lifespan. If you do frequent fine-sharpening, there's a chance you'll never be required to use coarse sharpening on your knife.

How fast can a sharpener sharpen a blade?

It depends on various factors. The main one is whether you're doing a first sharpening or re-sharpening. There are other factors like the unit's mechanics and overall quality. The process of sharpening knives is a meticulous job so it's more important to find a unit that will provide you with sharp knives.

How do you clean a knife sharpener?

This can be done easily by using a soft brush to dust off residue produced from sharpening. You should also use a damp towel to wipe the exterior to keep it shiny. You'll also need to rinse/wash the sharpeners from time to time using warm/soapy water.

Are electric sharpeners better than stone sharpeners?

Stone sharpening can be very effective in sharpening blades. The "problem" is it takes the proper equipment and several years of experience.

In fact, while stone sharpening can produce super-sharp blades, you typically won't need blades that sharp. Electric knife sharpeners can make the process fast and easy. If you hone the knives on a regular basis, they'll stay sharp.

Can sharpeners be used for ceramic blades?

If you're sharpening ceramic blades, you should purchase a ceramic-specific unit. This is related to the sharpening surface. If it's very hard, then it's designed for metal blades.

Can a sharpener damage knives?

That's possible if you pick a low-quality unit. In fact, while some sharpeners just make the blade duller others damage or destroy it. Those are situations you'll want to avoid.

So it's important to take a few key steps. Select a quality unit so you won't have to worry about bad quality or performance. You should also read the instructions carefully so you can operate the unit properly.

​Can you use knife sharpeners for other items?

Some units can sharpen things like scissors, but this often requires attachments.
