What Is An Electric Knife Sharpener?

An electric knife sharpener offers faster results as compared to its manual counterparts. It’s so easy to use that the only skill you need is to turn the unit on and off. This rectangle-shaped unit is often built with three slots to hold the blade and a special polishing disk to refine the edge of your knife.

This type of knife sharpener is more efficient than the manual knife sharpeners because it offers 2-3 grinding wheels with different grit levels. To use, simply turn the machine on then place the blade into the slot and pull it toward you for about 2-3 times.

Watch this video to learn how to sharpen your knife with an electric sharpener:

Tips In Sharpening Knives

  • Sharpen your knives at least twice a year to ensure that the blades are fine
  • Make sure that the knife is placed at a 15-20 degree angle on the slot
  • Start with the coarsest surface and proceed to the finest
  • Even if your unit has a magnet or bin to collect the metal shards, rinse your knife and dry thoroughly with a cloth
  • Before sharpening, make sure that the blade fits the slots.

Why Use An Electric Knife Sharpener?

The selling point of electric knife sharpeners is their ability to sharpen knives really fast. Just a few slides in the slot and your blade is ready to go. Obviously, they don’t need much effort to operate because the powerful abrasive wheels will do sharpening for you.

Some models, like the Presto 08800 and Chef Choice 130, are built with precision angle guides so you don’t have to worry about setting angles. Electric sharpeners also work with all types of knives so you don’t have to switch from one unit to another.

However, it’s important to note that they come at a higher price. Another downside is that if you’re not careful, you can damage the blade easily. It’s important that you grasp the knife firmly while sliding it through the slots.

Cleaning And Maintaining Your Electric Sharpener

It’s imperative that you clean your electric sharpener regularly so you get the best results. To remove any debris inside the unit, loosen the screw at the bottom and remove the cover and the sharpening wheel. Shake the unit upside down and clean properly with a brush.

For the sharpening wheel, brush with a detergent and scrub the debris away. Rinse with water and dry for at least 24 hours. Never use detergent or abrasives on the motor, bearings, and any moving parts.

What To Look For Buying Your Best Electric Knife Sharpener

* ​​​Non-Slip Base

The best electric knife sharpener should be safe to use. Look for a non-slip bottom so your unit will remain securely in place while in use. You want your unit to be still as possible so your blade won’t slip and cut your finger on the process.

Most models use suction cups to keep them securely in place on the working surface. Others use elastomeric feet to keep a stable base.

* ​​Number Of Stages

The best models provide more than one stage for speed and performance. Most models come with two stages: stage 1 for sharpening the blade and stage 2 for honing the blade. If you want a quick sharpening before slicing a tomato, then look for stage 3 to refine the edge.

* Warranty

A warranty or a money back guarantee is what you should look for if you want to get the best value and extend the life of your product. Most durable knife sharpeners offer a lengthy warranty so you get a peace of mind whenever your product gets broken.

Some models even offer a 100% money back guarantee so you can get a full refund when you’re not satisfied with the quality.

* Material

If you want a high-quality knife sharpener, look for something that’s made of diamond material. Unlike other materials, diamond is very hard and will last long for a very long time. A model that uses this material is often expensive but you may see some cheap versions of it in less polish forms.

If you can’t afford a diamond knife sharpener, you may choose tungsten carbide, Sapphirite, or polished ceramic. Also, watch for the grit number which measures the abrasiveness of your unit. A higher grit number means a finer abrasiveness. For example, a 1000-grit material is quite fine while 120-grit is tremendously coarse.

* Ease Of Cleaning

When sharpening knives, you’ll often see some metal shards falling off the unit. This can be quite messy if your unit has nothing to collect or catch these small metal bits.

For a mess-free process, look for bins, plugs, or magnets to catch the metal shards and fillings. Make sure that the parts grinding wheels and easy to remove so you can easily discard the debris inside.

* Precision Blade Guides

A precision blade guide removes any guesswork in sharpening. This feature is ideal if you want to achieve perfect sharpening results each time. It holds the knife at the desired angle to ensure fool-proof sharpening.

Final Thoughts

Considering the buyer’s guide above, the best electric knife sharpener is the Chef’s Choice 250 Hybrid Diamond Hone 3 Stage Knife Sharpener.

This model is very durable because it’s made of 100% diamond abrasive surfaces and a 1-year warranty. Unlike its other peers, Chef Choice 250 features a 3-stage sharpening system at an affordable price.

Chef Choice 250 is also the only unit reviewed that offers a manual sharpening option. So even if the power is out, you can still sharpen your blade without any problem. This unit is also easy to clean and comes with non-slip feet.
