The invention relates to a single-piece metal strip having no weld seams and made of a polycrystalline metal, comprising at least one region in which the crystallites have a comparatively stronger anisotropic orientation, and at least one region in which the crystallites have a comparatively less strong anisotropic orientation, and wherein 0-20 X-ray diffractograms measured at two arbitrary points of the strip by way of CuKalpha radiation produce no statistically significant differences with respect to the position and shape of the respectively corresponding pikes, and to tweezers, supporting implants, and joint prostheses comprising said metal strip. The invention further relates to a roll method for obtaining said metal strip.
