  • Patent number: 12150574
    Abstract: A knife rack includes a box body having a bottom, a plurality of peripheral walls surrounding the bottom, an accommodating space surrounded by the peripheral walls and the bottom and an opening provided where the accommodating space communicates with the outside, a top cover covering the opening and provided with a plurality of long slotted holes, and a plurality of round balls set within the accommodating space of the box body and used as a support structure for supporting knifes. The point-like contact between the round balls and the blades of stored knives can greatly reduce the contact area between the round balls and the blades, and the gaps between the round balls are conducive to air circulation.
