  • Method for forming an etched soft edge metal foil and the product thereof
    Patent number: 7591955
    Abstract: A metal processing method includes etching to remove material from a thin metal part. A pattern of etch resistant material is used to prevent etching of the metal in desired locations. The etch resistant material is intentionally applied to unclean surfaces so that an adhesion between the etch resistant material and the metal will fail during the etching process. An edge is formed during etching at the boundaries of the pattern of the etch resistant material. These edges are rounded where the adhesion fails. A shaver foil is produced using the described metal processing method including a face side, a cutter side and a plurality of whisker holes. A face edge is formed where an etched profile of the whisker hole meets the face side and a cutter edge is formed where the etched profile of the whisker hole meets the cutter side. The face edge is rounded using the aforementioned process and the cutter edge is sharp using a conventional etch resistant material application method.
