Abstract:
A shaving/cutting device with directly deposited (formed) razor structures without the use of intermediate adhesives. The device is in the form of a substantially flat substrate with miniature razors that have been directly deposited and formed onto the surface of the substrate. The substrate is of a rigid or flexible nature. The substrate is substantially thin and is therefore flexible and its shape is rectangular, circular or oval in nature. The razors are substantially deposited in plurality as an array formation onto the surface of the substrate. In most cases the razor array formation is in the form of parallel, curved and concentric nature. Flat mesa structures that are substantially the same height as the razor structures are incorporated in the razor array formations. The methods of manufacturing one or more directly deposited razor structures and mesa structures is disclosed.
