Will the handle of the cooker rust or the wood fall off after being used for a long time?

No, the fast-running chef is good at using a knife and a kitchen knife. The kitchen knives in our hotel are basically fast-selling. I've been working for a year, but I haven't heard that the kitchen knife will fall off. My own kitchen knife is also a fast-running household kitchen knife. My family often cooks, and there is nothing wrong with knives.
