Abstract
A metal cutting board is integrally formed by a metal plate body and includes a first plate body, a second plate body, and an inclined connecting portion. The second plate body is disposed around a periphery of the first plate body, the second plate body and the first plate body are parallel to each other, and the second plate body and the first plate body are positioned on planes of different heights. The inclined connecting portion is circumferentially disposed between the first plate body and the second plate body. The first plate body, the second plate body, and the inclined connecting portion are integrally formed from the metal plate body and are connected to form a shallow tray structure.

A metal cutting board, comprising:
- a first plate body having a uniform thickness;
- a second plate body disposed around a periphery of the first plate body, the second plate body and the first plate body being parallel to each other, and the second plate body and the first plate body being positioned on planes of different heights;
- and
- an inclined connecting portion circumferentially disposed between the first plate body and the second plate body, an inner edge of the inclined connecting portion being connected to an outer edge of the first plate body, and an outer edge of the inclined connecting portion being connected to an inner edge of the second plate body;
- wherein the first plate body, the second plate body, and the inclined connecting portion are integrally formed with each other to form a metal plate body;
- wherein a ratio of a height to a width of the inclined connecting portion is within a range from 1:1 to 1:5;
- wherein, from a top view of the metal cutting board, the inclined connecting portion is disposed between the second plate body and the first plate body along a curved path that is not parallel to an outer periphery of the second plate body;
- wherein the curved path is surroundingly arranged between the outer periphery of the first plate body and an inner periphery of the second plate body;
- wherein the outer periphery of the second plate body has two first sides that are parallel to each other, two second sides that are parallel to each other and perpendicular to the two first sides, and four corners that are connected between the two first sides and the two second sides, wherein the curved path has two first curves adjacent to the two first sides, two second curves adjacent to the two second sides, and a curved connecting portion connected to a junction of the two first curves and the two second curves, wherein each of the two first curves forms an arc-shaped curve and has two ends being away from a corresponding one of the two first sides and a middle portion being curved in a direction towards the corresponding one of the two first sides, and wherein each of the two second curves forms an arc-shaped curve and has two ends being adjacent to a corresponding one of the two second sides and a middle portion being curved in a direction away from the corresponding one of the two second sides;
- wherein the metal plate body is a titanium metal plate;
- wherein a surface of the metal cutting board has a titanium oxide film layer having a thickness greater than 10 nm;
- wherein the titanium oxide film layer is formed by a stable titanium dioxide in a rutile crystal form.
