This knife and cutting board sterilizer solves problems typically related to cutlery and cutting boards. It uses UV sterilization to prevent the spread of mold and bacteria. The sterilizer is equipped with three dedicated cutting boards and knives for use with different foods. These include a raw meat board, a cooked meat board, and a vegetable and fruit board, each of which has its respective knife. The use of different utensils for different foods prevents cross-contamination and the spread of odors. The ultra-thin body is space-saving and provides convenient storage space for cutlery and cutting boards. The sterilizer is controlled by a start button and automatically turns off once the sterilization process is completed.
