1. An apparatus for providing a nonlinear line of weakness on a web material, the apparatus comprising:
a base comprising at least one counter component having a length (LCC) wherein the counter component comprises a nonlinear shape having-a shape width (W);
a support operatively engaged with the base;
a blade having a length (LB) and being disposed on the support so as to either contact or to come in close proximity with the counter component;
wherein at least one of the counter component and the blade has a nonlinear shape;
wherein at least one of the counter component and the blade comprises multiple segments;
wherein the base comprises a cylindrical base having a base longitudinal axis, wherein the base rotates about the base longitudinal axis, and the base longitudinal axis runs substantially perpendicular to a machine direction; and
wherein the counter component is helically mounted on the cylindrical base at an angle of greater than 0 degrees to about 45 degrees to the base longitudinal axis.
