Abstract

A razor cartridge includes razor blade assemblies having an inter-blade guard attached to a side of a razor blade. The razor blade is formed from strip that is manufactured including a thermal oxidation process to form a chromium oxide layer on the side surface of the razor blade. This oxide film prevents electrochemical corrosion of the razor blade that may be visible to a user and prevents real or perceived premature failure of the razor blade and thus the razor cartridge during its extended life. The razor blade assembly may also have an array of closely spaced droplets of a liquid adapted to inhibit corrosion of the razor blade applied to the side of the razor blade visible to a user.
