What is the best maintenance for Japanese blades?
Kitchen cutlery should be lightly oiled and kept in their original boxes or away from other cutlery when stored. After use, they should be rinsed, dried and put away. Carter cutlery should not be put in the dishwasher. Outdoor cutlery should be treated with the same respect, lightly oiled, and returned to their sheathes after use. Any discoloration of the steel edge that will occur over time will not affect the performance of the knives. Sharpening will remove any discoloration.
