ABSTRACT:
The present invention relates to razor blade cutting edges which exhibit an improvement in the first shave. Conventional razor blade cutting edges exhibit surprisingly high initial cutting forces. Razor blades produced according to the present process exhibit significantly lower initial cutting forces which correlates with a more comfortable first shave. Improved blades according to the present invention involve treating conventional razor blade cutting edges having an adherent polyfluorocarbon coating with a solvent to partially remove some of the coating. Preferred solvents include perfluoroalkanes, perfluorocycloalkanes, perfluoropolyethers having a critical temperature or boiling point above the dissolution temperature for the polyfluorocarbon in the solvent. The present invention also relates to the method of producing these razor blade cutting edges.
