How Do You Sharpen Japanese Knives?

The steps that you need to follow for resurrecting the sharpness of the blades are:

  1.  First, you will have to clean both sides of the blade so that it does make the carbides of the sharpeners gunky,
  2. After cleaning both sides, use a soft cloth to dry the surface off.
  3. Then you will have to bring out the sharpener that you got, place it on a flat surface if possible.
  4. Adjust the sharpening angle if the mechanism is present on the sharpener that you got.
  5. Slowly drag the edges through the carbides of the sharpener. You will have to check the sharpening amount after each drags, or you might shave excess metal off the blades.
  6. After a couple of drags, you should have a blade that should be as sharp as it was when you first got it.

What to Look for Before Buying?

Before you get yourself one of the sharpeners from the market to resurrect the sharpness of the blades, you will have to keep some factors in mind. These will allow you to scrutinize the units properly and get the most out of the money that you are going to spend on it. They are:

Functionality

The first thing that you have to consider is whether the unit can fulfill its original purpose or not. That is whether it can sharpen blades properly. For that, what you have to factor in is the carbides that it uses for the sharpening process.

Keeping that in mind, we would recommend you to opt for the ones that come with a diamond-honed tungsten carbide tip.

And for the automatic commercial ones, you will have to factor in the quality of the belt. If the belt is of average quality, you will not be able to get proper sharpening on the blade. Those will only shave off some metal off the surface.

Ease of Use

The traditional way of sharpening blades is by using whetstones. But decent sharpeners that are similar to the ones that we included in our list makes the task effortless.

And you should consider the overall sharpening process if you want to resurrect the sharpness of the blades without any hassles. The units should come with some sort of instructions that will make the process easy for you.

Stability

For the electric and manual multi-slotted sharpers, you will have to consider the stability too. In that case, what you should factor in is the base of the unit.

We would suggest you go for the ones that come with rubber coating on the bottom. Those will stay secure on a flat surface and will not move when you are sharpening blades on it.

Durability

The last thing that you have to consider is the build quality of the body and the blades. Even though we are putting this in the last, it does not mean it is of less importance. For being able to sharpen your knives for an extended amount of time, you should go with the ones that have a durable body and carbide tips.

Frequently Asked Questions

  • Should I push or pull through the slots of the knife sharpener?

Well, the instructions should be stated in the manual of the unit that you got. Some will work the best with pushing, while some will work with pulling. For getting the best results, you should follow the instruction properly.

  • Should I sharpen the blade regularly?

No, you should only sharpen them once the edges become dull, and you face difficulties in case of cutting food using it. But you can hone it regularly.

  • How often should I sharpen the blades?

The time period between each of the sharpening will vary from knife to knife. Usually, the stainless steel ones will require comparatively less sharpening and horning than carbon steel ones. However, we would recommend you to sharpen two to three times a year.

  • What does honing mean?

If the edges of the knife are already sharp, you should hone it to maintain the sharpness. It is basically polishing the rough surfaces, which will allow the blade to retain its edge for an extended amount of time.

  • Is it worth getting a sharpener?

Yes, they are definitely worth the money, at least according to us. With them, you will be able to use the same knife for an extended amount of time.

Final Words

The best Japanese knife sharpener will not only allow you to extend the overall lifespan of the valuable knife but also will make your cutting tasks an absolute breeze.

And we hope we were able to make choosing one easier for you. With that, we would like to wrap it up here by wishing you good luck and hoping that your Japanese knife lasts for an extended time.
