To avoid unexpected problems, we recommend that you keep your knives as sharp as possible. This makes it easy for you to perform food preparation tasks smoothly and safely.

2. The correct Japanese knives sharpening angle

In general, the standard Japanese chef's knife usually has a correct knife sharpening angle of 30 to 40 degrees. However, this is the sum of both sides of the blade, formed from grinding both sides with bevels. For most popular knives, their edge is formed as a symmetrical V, with a 15-degree sharpening angle on each side, creating a total angle of 30 degrees.

However, single bevel knives are different. With this type of knife, one side of the blade is flat, and with a 15-degree sharpening angle on one side, the total sharpening angle is 15 degrees. This creates an extremely sharp edge.

The single bevel of Japanese knives, especially in Japanese cuisine, is not only a design element, but also reflects the thinking and philosophy behind the art of cooking. The knife is optimized to perform cutting tasks accurately and efficiently, especially in preparing sushi and sashimi. This specialization in design not only enhances cutting performance but also demonstrates respect for the art of cooking and ingredients.

The blade is created so that one side has a sharp edge, helping to create thin and even cuts. This specialization not only provides greater control when cutting, but also demonstrates the chef's seriousness and dedication to the art of cooking. In this context, knives are not just tools, but also a symbol of passion and creativity for creating great meals.

Why are Japanese knives sharpened on one side? This action is not only a technique, but also a part of philosophy, creating uniqueness and depth in the culinary art of the Land of the Rising Sun.

For most Japanese knives, without specific instructions from the manufacturer, choosing a Japanese knives sharpening angle between 15 and 20 degrees and using it to create a 30 - 40 degree edge is a safe choice. Note that the bevel on one side is not an edge, so to get a 30 degree edge you will need to grind each side at a 15 degree angle.

This approach helps recreate the knife's original edge, and for most Japanese knives, a sharpening angle of 15 to 20 degrees is common. However, if you are not sure, start with a 15-degree angle and gradually increase until you find the angle that best suits your needs.

If you need to determine the Japanese knife sharpening angle for your knife without specific instructions from the manufacturer, you can use a laser protractor or a regular protractor to try and determine the angle. However, this can be more complicated because the edge of the knife can be dull, making angle measurements difficult and inaccurate.

A safe choice for most Japanese knives is to choose a Japanese knives sharpening angle of 15 to 20 degrees for each side of the blade. This will create a total sharpening angle of 30 to 40 degrees, which is a common standard for Japanese knives. This helps ensure the sharpness of the blade and also helps maintain its durability.

Remember, the angle of sharpening one side is not the edge, so to get a total edge of 30 degrees, you will need to sharpen both sides of the blade at a bevel, each side at 15 degrees. This helps you maintain knife sharpness and optimize cutting performance.

Below is a guide to the average knife sharpening angle that some leading knife manufacturers recommend:

  • Chef knife blade angle on each side = 15 degrees
  • Paring knife blade angle on each side = 14 degrees
  • Utility knife blade angle on each side = 15 Degrees
  • Fillet blade angle on each side = 16 Degree

3. Is there any difference between 15 degree and 20 degree knife edge?

The main difference between the 15-degree and 20-degree grind is that the 15-degree blade is sharper and sharpens faster, providing a smoother cut. However, at the same time, it also requires more regular maintenance to maintain its sharpness. On the contrary, the 20-degree sharpening angle has stronger durability, but does not achieve as high sharpness as the 15-degree angle.

Deciding between the two Japanese knives sharpening angle depends not only on personal preference but also on your intended use of the knife. If you are looking for a multi-purpose knife, the 20-degree sharpening angle may be the right choice. However, if you want a versatile knife capable of handling complex tasks like cutting fruits and vegetables, the 15-degree sharpening angle may be a better choice.

There is no right or wrong answer when choosing between these Japanese knives angle, but it depends on the specific factors you are looking for in a knife and your personal preferences.

6.1. Dry Grinding Stone:

This method is a traditional Japanese grinding method that does not require assistance from other lubricants. Its special thing is that it is simple and does not require any other equipment. However, it is important to note that using dry sharpening stones can harden the blade, especially when using low-cut sharpening stones. To reduce this risk, you should choose grinding wheels with higher roughness (from 3000 or higher).

6.2. Water Grinding Stone:

The most common method in Japanese knife sharpening, using water helps protect the blade and makes the sharpening process smooth and effective. To start, you need to soak the sharpening stone in water for about 10 minutes before using. Remember to add more water when the ice begins to dry to maintain the best performance. Although it requires maintaining moisture, this method is often appreciated for its ability to keep blades sharp and precise.

6.3. Oil Grinding Stone:

This method is not common but offers the advantage of not drying the grinding wheel as quickly. Before use, you need to soak the grinding stone in oil for about 10 minutes. Then, wet the blade and begin the sharpening process. When the wheel begins to dry, add oil to keep it lubricated. Although more complicated than other grinding methods, oil grinding wheels are still a unique, high-performance choice.
