The finite-width correction terms to the Nambu action for Nielsen-Olesen strings are calculated. They consist of an extrinsic curvature squared or rigidity term and a new "twist" term. The extrinsic curvature term prevents cusps forming, rounding them off with a curvature radius of the order of the string width.
