Steel blades are prone to rust if not properly cared for. To prevent rusting, it is essential to perform appropriate maintenance and storage after use.

After each use, clean the blade thoroughly using detergent or similar cleaning agents. Then, use a dry towel or cloth to completely wipe away any moisture.

Some people may consider using fire to sterilize and dry knives, but this is strictly prohibited. Heating the blade can cause it to lose its temper, resulting in a significant decrease in sharpness. If you wish to sterilize, it is recommended to use boiling water disinfection instead.

If the blade will not be used for a while, lightly apply blade maintenance oil or vegetable oil, such as salad oil, to prevent rust. For knives and hatchets, we recommend using specialized blade maintenance oil.

It is important to note that salad oil may become sticky and difficult to remove over time. If the blades will be stored for an extended period, it is advisable to wash off the oil and reapply it at least once a year or use specialized blade maintenance oil.

Afterward, it is recommended to store the blades wrapped in newspaper. Ensure that they are thoroughly dried and store them in a dry location. Newspaper acts as a barrier against moisture, making it an ideal storage method.

If the blades are in a case, such as traditional Japanese knives, remove them from the case and wrap them in newspaper for storage.
