What to Look for When Choosing the Best Kitchen Knife Sharpener

With the information overload of multiple features advertised online, you may sometimes feel lost about what you need to look for in a knife sharpener. Here is what you need to check out before settle on a particular model.

Manual vs. Electric

In a manual model, you will have to adjust the pressure and the angle of sharpening action, in addition to calculating the number of passes required to sharpen the knife. In an electric model, you only need to run the blade through the stones a few times.

Edge angle

Knives have bevels on both sides and the edge angle determines the cutting efficiency. There are typically two edge angles, 15 degrees and 20 degrees. Make sure that the sharpener you choose permits you to sharpen both edge angles.

Specialty sharpening

Knives come in different sizes and shapes – chef’s knife, Japanese knives, butcher’s knife, hunting knife, pocket knife, serrated edge knives, and extremely smooth-edged knives. The sharpener needs to meet all sharpening needs.


Look for a model that offers convenience and speed. Ideally, your knives need to be sharpened in a maximum of three passes through the coarse stones. And you should not be expected to adjust your pressure with precision.


The knife sharpener needs to offer versatile functions – you may need serrated edges to be sharpened, you may want to polish the knife, in addition to sharpening the dull edges.


The price range extends from a little above 10 dollars to a little above 150 dollars. All factors need to be considered and weighed before you settle on a price band. For instance, a manual model will be a lot cheaper, when compared with an electric model.


Look for a product that offers the maximum warranty for the materials and workmanship. Rusting is usually not covered by warranty, as all materials are likely to rust if proper care is not taken. You will find that most companies offer anywhere between one to three years of warranty.

Benefits Of Electric Knife Sharpeners

It is possible that you may be wondering about the specific benefits of a knife sharpener. You are obviously aware that it sharpens survival knives, but you may not have looked at the clear advantages of using a good knife sharpener. Here are the top four benefits :

Individuals may sometimes scrape/rub knives against coarse stones in an effort to sharpen it. If this is not performed with the right amount of pressure, the knife will end up with uneven edges.

#2. Prolongs Life Of Knives

EDC Knives that are sharpened will require lesser pressure and will therefore experience lesser wear and tear, resulting in longer use of the same knife.

#3. Helps To Complete Cooking Faster

With sharper knives, it is possible to complete cutting of ingredients faster, which helps in finishing cooking faster.

#4. Simple, Safe And Convenient

A knife sharpener is simple, safe and convenient to use. Knives can be sharpened without any special skills or training.

How To Use Knife Sharpening System

Using a top rated knife sharpener is pretty easy. There are simple instructions that need to be followed to ensure that the knife is sharpened the right way.
#1. The knife blade should be pulled through the coarse slot first, followed by pulling it through other slots progressively.
#2. The blades should always be pulled in a single direction, i.e. from the base of the blade to the tip, and never in a back and forth motion.
#3. Ideally, the number of passes that are required for sharpening a blade are two through every slot.
#4. The blade needs to be washed after sharpening though sharpeners collect the shavings form the blade.


Choose the best kitchen knife sharpener after carefully assessing each model’s features in the knife sharpener reviews. Bear in mind that you need to look for a sharpener that is extremely convenient to use, one that is safe, offering the best results. The durability of the sharpener and its maintenance also needs to be considered before you compare the prices of different models.
