Chopping potato slices quickly and making each slice evenly thick requires certain skills, especially for white-collar workers who don’t often cook. In order to solve this problem, a foreign female student designed a ZON kitchen knife set. With this kitchen knife set, you will also be a master of slicing. This set comes with 4 knives and a scabbard. You can put four knives into the scabbard at the same time. The speed of cutting vegetables is increased by four times. The thickness of each slice is cut very evenly, and four slices can be cut with one knife. ,save time and energy. Of course, each knife can be taken out and used individually. But this also brings up a question: after making a cut, will food clog the inside of the blade? This is something designers need to consider.
