As described above, judging comprehensively, since Pt was used as an auxiliary material to enhance the adhesion of DLC and prevent peeling, the cutting edge of the razor blade was improved to improve the sharpness of the razor blade, and the sharpness was improved. Can be maintained, and the durability can be improved. In addition, it can be confirmed that Zr, Ni, and Cr as well as the auxiliary material have the same effect as Pt. When attention is paid only to the effect produced by the auxiliary material, as the coating layer 2, FIG. 1 (b), FIG. 2 and FIG.
3 (b), 4 (a), 4 (b), 4 (c) and 4 (d). Furthermore, N
Since i has antibacterial properties, it is hygienic when used.
