    摘要: [Problem] To provide a medical cutting tool with low impalement resistance. [Solution] The edged medical cutting tool comprising a knife, trocar or cutting suture needle has a sharp edge (1) for incising living tissue and a flat part (2) that configures the edge, and the color of the portion of the flat part (2a) along the edge (1) differs from the color of the rest of the flat part (2b). The difference in color results from a difference in the thickness of an oxide film. Another edged medical cutting tool is configured of austenite stainless steel and has a sharp edge (1) for incising living tissue and a flat part (2) that configures the edge. The chrome content of the portion of the flat part (2a) along the edge is higher than the chrome content of the rest of the flat part (2b).
