any kitchenware needs maintenance, not to mention such a high-end knife as zwilling! I think the maintenance of knives should be divided into two aspects. One is sharpening knives. ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ Another is that in the process of cooking, different dishes should be cut with different knives. For example, if you use a bread knife to cut bread when deboning, it will definitely damage the knife. Of course, you should use a special boning knife, which is called a special knife. When cooking, be sure to keep the knife away from the cooker, because overheating can damage it and may also cause burns, and you must clean it in time after contacting acidic or corrosive juices such as tomato juice and lemon juice! Otherwise it will rust, too.

finally, sharpen your knife more often when you have nothing to do. Anyway, the two people sharpen their knives for free for life.
