・Regardless of the steel material, please wash it off after use and wipe off any moisture.

・Please refrain from using in the dishwasher or dryer.

・Do not pour boiling water over it or heat it with a burner.

・Please thaw frozen foods thoroughly before cutting.

- If rust appears, remove it with a commercially available rust remover (rust remover rubber, etc.).

- If the sharpness decreases, sharpen it with a whetstone (medium whetstone = about 1000 to 2000).

- Sharpener is not recommended, but if you do use it, please use it only as a temporary measure.

・When cutting hard objects, be careful not to twist the cut while cutting. This may cause the blade to spill.

・When storing for a long period of time, spread a thin layer of oil such as camellia oil on the blade and store it wrapped in newspaper, etc.
