*This post may contain affiliate links. Please see my disclosure to learn more.

Japanese knives are known for their sharpness and durability but they still have to be maintained and sharpened just like any other knife out there. 

If you’re going to spend the money on a high-quality knife set like a Japanese knife, then you need to be prepared to care for the blade and sharpen it when necessary.

There are a lot of different knife sharpeners out there and they are made in a lot of different ways. From simple, handheld sharpeners to heavy-duty sharpening blocks and even electric sharpeners, the options are just about endless… and equally overwhelming. 

What you will find is that most sharpeners are not specifically labeled as Japanese knife sharpeners so there are other qualities to look for to ensure your sharpener can handle the angled construction of your knife.

What makes the best Japanese knife sharpener? For a Japanese knife, you want a sharpener that offers an angle of around 14-17 degrees (less than 20). A manual pull-through sharpener is often best, but some electric sharpeners will do the job. Whetstones can be difficult to learn but work quite well.

In this guide, we will share with you the 9 best Japanese knife sharpeners on the market!

While you can easily search knife sharpeners, you need to really be able to narrow them down to the best fit for this style of blade. We’ve got you covered with some really great options.

Keep reading to learn about the 9 best Japanese knife sharpeners and more. 

How to Choose a Japanese Knife Sharpener

As we mentioned earlier, you may or may not find a knife sharpener that is actually labeled as a Japanese knife sharpener.

It’s great if you can find a multi-functional sharpener that is specified to be ideal for a Japanese blade, but there are other ways to find a suitable option. 

Before you start looking around, we felt it was vital to share some details as to what you might want to look out for. Whether you want something manual or electric, you will need to keep some key criteria in mind to ensure that the sharpener you choose will truly work for your Japanese blade. 

Let’s take a look. 

Ease of Use

One essential element of your decision should be how easy the knife sharpener is to use.

You certainly don’t want something so complicated or challenging that is going to take you a ton of time to figure out or work with. Having a sharpener that is simple and efficient is really the best way to go. 

Ease of use might vary by person. A simple whetstone with an angle holder or manual pull-through sharpener might be simple and ideal for one person. But another person may prefer the ease of an electric option.

Type of Sharpener

This is another important consideration. There are a lot of different types of knife sharpeners out there.

When you’re looking at sharpeners, you will find simple, manual options, which are perhaps the most popular choice.

These tend to be whetstones – which are tough and heavy stone blocks for sharpening your knife against, or pull-through sharpeners, which typically have multiple “cubbies” which sharpen your knife as you pull it through/

In addition, there are also electric sharpeners, which tend to look just like the pull-through models, only they involve more settings and less labor.

For a Japanese knife, using a manual sharpening block or whetstone is probably your best option. Whetstones can take time to master, but if you put in a little time, the pay off is high. However, you can use an electric sharpener if you find a quality choice.

We do recommend looking at the details of any sharpener you browse to be sure they mention they are suitable for Japanese or “Asian” knives. Not all sharpeners are suitable for all knife types.


One of the main things that you will want to watch for is the angle of the sharpener. A lot of standard sharpeners will be set to sharpen at an angle that is around 20-24 degrees. This is too high for a Japanese knife. 

You will either want a sharpener that lets you adjust the angle or one that is designed for a Japanese knife angle specifically.

You should expect your angle to be around 14-17 degrees when you are working with a Japanese knife, with the most common being 15 degrees. 

This is very important as if the angle is too high, you can easily ruin or degrade the quality and design of your Japanese knife. This is a risk you shouldn’t take. Check the angle every single time! 


While we are specifically looking for a knife sharpener to sharpen Japanese knives, it’s nice to find an option that has some versatility to it.

What you will find is that a lot of sharpeners are designed to handle multiple knife styles. While not every sharpener has that versatility, it’s certainly something that you might want to keep in mind or even specifically look for. 

Versatility just allows you to be able to get the best use out of your sharpener without requiring you to have multiple sharpening tools in your kitchen. 

Understanding How to Use a Knife Sharpener

You can get the very best knife sharpener but the truth is, if you don’t know how to use it, it won’t be effective. No matter what knife sharpener you choose to purchase, be sure that you take the time to learn how to use it properly. 

You won’t just want to know how to use the sharpener but more specifically how to use it for a Japanese knife. Remember that these knives have angled blades so proper use of the sharpener will make a difference and it’s up to you to learn just how to master the sharpener to take the best possible care of your blade. 

The means by which you use a sharpener could vary depending on the sharpener so we recommend looking for instructions specific to the sharpener you are using to really get it right.

  1. Agreed with you on the Smith’s 50264—it seems to support many edge angles but the slots are not stable, so more often than not you’ll just end up destroying your knife edge. I learned that the hard way. The Kitchellence is much more stable (and cheaper).
