A razor blade is so sharp designers measure the edge in angstroms. 1 angstrom = 1/10,000,000 of a millimeter. A sheet of copy paper is about 1,000,000 angstroms thick. The extreme edge of a razor blade can be less than 300 angstroms thick, which means it is less than 1/1,000 the diameter of a human hair. We are talking about nano-scale technology.
