1. What is a KANZEN Knife? A thorough explanation of its features and appeal
The KANZEN Knife is a high-quality knife that has been developed to be easy for anyone to use and to offer professional-level sharpness. Its greatest feature is that it combines high sharpness with ease of maintenance.

-
100% made from super stainless steel "V Gold No. 10":
The KANZEN Knife is made entirely of the highest quality stainless steel, V Gold No. 10, which is usually only used for the cutting edge. This allows for the blade to be as sharp as a steel knife, with the same ease of care as a stainless steel knife. -
Uniquely shaped handle for ease of use:
The Kanzenmuki Knife's uniquely designed handle fits comfortably in your hand and is designed to reduce fatigue even when used for long periods of time. The blade moves smoothly with little pressure, making everyday cooking more comfortable and enjoyable.
2. The background to the birth of the KANZEN Knife: Brand philosophy and the story behind its development
Tashinam's founder, Masaru Matsuya, decided to develop the KANZEN Knife out of a strong desire to revitalize traditional Japanese culture.

-
Passing on traditional culture to the next generation:
Tashinam's mission is to increase demand for traditional industries and pass on our rich culture to the future by incorporating artisanal techniques into modern life. During the development process of the KANZEN Knife, we listened to the opinions of local artisans, professional chefs, and ordinary home cooks, and repeatedly improved the knife's ease of use and quality. -
The concept is "The best sharpness for everyone":
Our goal is to create a knife that does not require the special maintenance that is common with high-end knives, and that maintains its outstanding sharpness with regular care, so we have paid meticulous attention to everything from material selection and sharpening techniques to process management.
3. Careful attention to materials and construction creates the sharpness of the KANZEN Knife
The KANZEN Knife is made entirely from the highest quality super stainless steel, V Gold No. 10. This allows for a unique manufacturing process that allows the high-quality steel, usually only used at the cutting edge, to be spread throughout the entire blade.

- Blade edge polished to approximately 0.001 mm:
The blade edge is so smooth that it is invisible to the naked eye, ensuring a delicate sharpness not found in mid-priced knives. It produces beautiful, uniform cuts from soft ingredients to hard root vegetables.

- Sharpness that lasts 3 times longer than competitors:
Tashinam's unique "sharpness test" has confirmed that the KANZEN Knife stays sharp for approximately three times longer than other companies' products.

- Deliciousness proven by taste sensors:
A taste sensor analysis conducted by Keio University and AISSY showed that ingredients cut with the KANZEN Knife have a more pronounced umami, sweetness, and richness. The knife is highly acclaimed not only for its sharpness, but also for its ability to bring out the natural flavor of ingredients to the fullest.
4. KANZEN Knife: a quality product made by skilled artisans

Each and every Kanzenmuki knife is meticulously crafted by a craftsman, right down to the final sharpening. Fine adjustments not possible with mass production and uncompromising process management ensure the quality of the finished product that reaches the user.
This craftsmanship and time and effort supports the quality of the KANZEN Knife and enhances the brand value of the KANZEN Knife.
5. Tips for mastering the KANZEN Knife: Cutting more comfortably by pulling the knife back and forth
No special techniques or gripping techniques are required, but to make the most of the excellent sharpness of the KANZEN Knife, try cutting by pulling the blade back and forth.

- Pull back and forth:
By moving the blade little by little without using excessive force, the blade will naturally cut into the food. Even hard ingredients and delicate slices will not crumble easily, and you can easily achieve a beautiful finish, allowing you to fully enjoy the performance of the KANZEN Knife.
6. Maintenance methods for using the "KANZEN Knife" for a long time
The KANZEN Knife can be easily maintained just like a stainless steel knife.
After use, wash thoroughly with a neutral detergent and a coarse sponge, then wipe off any excess water before storing.
This alone will help you maintain the original condition of your knife in good condition.
- For resharpening, we recommend using a whetstone:
If you feel that the blade has lost its sharpness, you can restore it to its original sharpness by resharpening it with a whetstone. Although using a sharpener is not recommended, there is a safe method that you can rely on. - Tashinam's sharpening service:
To ensure you can enjoy using your KANZEN Knife for as long as possible, Tashinam offers an official resharpening service. Our expert staff will carefully sharpen each knife to restore its ideal sharpness. If you are using a whetstone for the first time or are not confident in maintaining your knife yourself, we recommend that you take advantage of Tashinam's resharpening service.
