Best Electric Knife Sharpeners Reviews 2020: Top 5 Picks

Sharpening Steels

Even in the ancient times, people who have used knives also needed the means to sharpen them, even if it is using a simple rock. Any hard and rough surface which is harder than the knives can make it sharp. A window sill and sandstone were also considered to be used when sharpening the knife.

There is no record of when and who actually invented the first sharpening steel.

According to the study done by University of Colorado, “prehistoric people developed a method of sharpening tools and stone knives at least 75,000 years ago".

”The “Moletas” or the western style grinding or sharpening can actually be traced back all the way from Northern Italy. Trento, Italy became the center of knife grinding tradition.

  • DID YOU KNOW? The smaller the angle between the blade and stone, the sharper the knife will be.


  • Sharpening/Grinding – it is the process of removing metal to form a new edge.
    • Rough Sharpening (this is for Oil stones, Water stones, and sandpaper)
    • Fine Sharpening (this is for finer grits)
  • Straightening/Steeling – it is the process of straightening the metal on the blade but not exactly removing a significant edge.
  • Polishing/Stropping - it is the process doing renewing the blade by giving it a mirror finish but not exactly altering the edge.

Blood Damage

When blades are damaged by a compressive force or also known as buckling and if pressed into a hard object just like bone or ice and also by bending from sideways pressure, it rolls the edge of the blade due to metal ductile nature.

  • DID YOU KNOW? Blades can be damaged just by simply cutting lemons and tomatoes because of their acid.


  • Once you are done using your knife, you have to clean it right away but NOT with a use of harsh detergents.
  • Elias Cairo, chef and owner of Olympia Provisions said that “I had the same knives since I was 15, I don’t like to use harsh detergents on my knives, I wash them with mild soap with my hands and immediately wipes them dry after I wash it.” Because the pressure of the dishwasher can knock the knives around that would dull the blade.
  • This is probably the most important one: Using the right knife – It would be great if you know which knife is appropriate for meat, vegetables, fruits etc.
    • Thinner Blade – is supposed to be used on cut fillets, roast for stuffing or butterfly steak.
    • Thicker Blade – is supposed to be used for chopping or slicing.
  • Oiling (with food grade oil) is advisable as well
  • Slicing Paper – If you can slice a paper effortlessly with your knife and it doesn’t catch even a tiny bit of tear then your knife is indeed sharp.
  • Shaving Sharp – Shaving hair in your arms with your knife means your knife is incredibly sharp and it doesn’t need to undergo other tests.
  • Fingernail trick – *this can be dangerous so you have to be extremely careful* Lay the edge of your knife very gently on your fingernail. If the knife bits into your fingernail then your knife is very sharp.
  • Slice an Onion – An onion as we all know is very slipper and its skin is very thin so if your knife can easily catch and bit into the skin of an onion then it is sharp.

This knife sharpener is very quick and very easy to use. This has ceramic wheels with diamonds on them but it only features one sharpening stage, therefore, you cannot expect it to get polished. And because it doesn’t have any stages, it is not too complicated to use, unlike the previous ones. You just pass the knife through the slot and simply get it out. There you have it, simple as that.

Things We Liked

  • This knife sharpener can handle a 20-degree angle
  • This is best for European knives
  • Perfect for a normal household chef

Things We Didn't Like

  • It only features 1 stage
  • It doesn’t polish or use finer diamonds
  • Not good for high-quality knives or serrated knives


Every knife sharpener has different features but the best one for me is the Presto 08800 EverSharp. It is précised and not too complicated to use. It is best for unprofessional chefs or the people who only started to use their kitchen. It always depends on your choice and your abilities. If you are a pro then go for the Chef’s Choice ones since it has more features. But if you are in between pro and amateur just asses what you really need and what kind of skills you have.
