Toshio Odate has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Sharpening apparatus for plane iron crowning
    Patent number: 8529316
    Abstract: A sharpening apparatus having a slightly convexly or concavely curved abrasive surface, for use in sharpening woodworking tools or in other fields requiring such processing of precision parts or tools. The invention may further employ either cylindrical or conic abrasive surfaces. Cylindrical abrasive surfaces are desirable when a curvature of a fixed radius is desired, or where accuracy of the curvature radius is required. Conic or semi-conic surfaces may be used to enable a user, by means of short sharpening strokes, to achieve an approximate desired curvature among a range of possible curvatures provided along the length of the abrasive surface as the curvature radius progressively declines. In this way, one abrasive surface may be used to achieve a variety of curvatures.
