How do you make your knives stay sharp? Well, it’s a no-brainer: with knife sharpeners!

Practically, there are thousands of different knife sharpeners around the world to choose from. From the cheapest to the bank breakers, we will be taking a look at what I think are today’s 3 best knife sharpeners that can bring the edge back of your dull knives.

But first things first: go and check your favorite knives if they are still sharp. If not, then, this article will definitely help you decide the best knife sharpener for you. Take note though, if your knives are Japanese -made or Japanese Influenced, then, you should NEVER EVER use knife sharpeners. Instead, use a whetstone or a special knife sharpener that is specifically built for these kinds of blades.

Before we discuss the 3 best knife sharpeners on our list, let us first take a look at the difference between Japanese-Made/Influenced Knives and Western-made Knives. Also, what are the characteristics that we should look for when choosing a knife sharpener?

Japanese-Made Knives VS. Western-Made Knives
  1. Material

Japanese made knives are made from two types of substances which are hard steel and soft iron that is forged together. While western knives are made only of hard steel.

  • Hardness & Sharpness

Compared to western made knives,  Japanese-made knives are harder and sharper because of the materials that were used in forging the blades of the knives. Based on the Rockwell Scale, the hardness of Japanese-made knives ranges between 62-64 RHC. For Western-made knives, their Rockwell Scale usually ranges just between 52-56 RHC. This means that Japanese-made knives have better cutting quality compared to their Western-made knives counterpart. The only downside of Japanese-made knives is that because of its higher  Rockwell scale, Japanese-made knives are more difficult to sharpen.

  • Weight

Which knife do you think is lighter? I think you already have an idea about this. Japanese-made knives are more lightweight compared to Western-made knives. Japanese knives are specifically made to be handled by smaller hands for faster cutting and slicing.

  • Lifetime

Because Western knives are softer than Japanese knives, they are also sharpened more often, thus, making their lifespan is shorter compared to Japanese knives.

Characteristics That Makes A Good Knife Sharpener.
  • Ability to produce smooth edges

Whether electric or manual, the ability to produce smooth edges without damaging the blade of the knife is the most important feature of a knife sharpener that you should look for. Also, choose a knife sharpener that is best suited for the kind of knife that you are using.

  • Choose a knife sharpener with a hard surface

There are three types of knife sharpener materials that you can choose from: diamond, polished ceramic and tungsten carbine. Of these three, the diamond sharpening material is the hardest.

  • Multiple sharpening stages

It is wise to choose a knife sharpener with multiple sharpening edges because you can use this in sharpening different dull or damaged knives that you do not want to throw away. At the first stage, the knife is sharpened and a small material is removed, while at the last stage the finer stone material only polishes the knife and gives the blade a smooth edge.

  • Safety features

Even experts opt for knife sharpeners that come with great safety features. The most important thing to remember when choosing a knife sharpener is that it should be comfortable and safe to use so that accidents such as cutting your fingers while sharpening a dull knife is avoided.
