ABSTRACT:
A process for forming a razor blade includes the steps of providing a polycrystalline ceramic substrate of less than two micrometer grain size, mechanically abrading an edge of the polycrystalline ceramic substrate to form a sharpened edge thereon that has an included angle of less than twenty degrees; and sputter-etching the sharpened edge to reduce the tip radius to less than 300 Angstroms and form a cutting edge. The resulting blades exhibit excellent shaving properties.
