1. A method for preserving a precision edge of a precision-edged substrate comprising:
- providing a precision-edged substrate, wherein the precision-edged substrate is a cutting apparatus; and
applying to said substrate a coating made from a diamond-like solid state material formed from interpenetrating networks comprising a diamond-like carbon network stabilized by hydrogen, a silicon network stabilized by oxygen, and optionally at least one network made from dopant elements or dopant compounds containing elements from Groups 1-7b and 8 of the periodic table.
