1. A cutting device comprising:
a working blade body having a top surface and a bottom surface, wherein the working blade body defines a plurality of apertures extending between the top surface and the bottom surface, wherein the working blade body defines a plurality of countersunk edge pairs that each substantially surround a corresponding one of the apertures at the top surface and the bottom surface, wherein the working blade body is substantially within a plane; and
a plurality of static components each having a top portion and a bottom portion, wherein each static component is associated with one of the apertures and has a middle portion that is between the top portion and the bottom portion and positioned within the associated aperture, and wherein the top portion and the bottom portion of each static component are moveable within the countersunk edge pairs;
wherein each static component comprises a joint and load-sharing member, wherein the joint attaches the load-sharing member to the working blade body, and wherein each load-sharing member is defined to fit to a respective aperture and countersunk edge pairs with spacings such that a respective static component is moveable within the aperture and along the plane and moveable in a substantially less amount in directions outside of the plane for substantially maintaining movement of the static component with the plane of the working blade body.
