Abstract

A manufacturing method by wire electro-erosion comprising the following steps of providing a wire electro-erosion machine having a cutting wire; mounting at least one workpiece to the wire electro-erosion machine; making a surface micro-topography by wire electro-erosion; performing a first through cut on the workpiece according to a cutting path comprising peaks and valleys, thus exposing an exposed portion on the workpiece comprising reliefs and recesses corresponding to said peaks and valleys of the first cutting path. A surgical instrument comprises at least one gripping surface comprising a surface micro-topography.
