  • Patent number: 4912881
    Abstract: This invention provides a device that assists in the manual abrading and dressing at a selected angle of the edges of tools and other materials. The device can be mounted on a workbench and comprises a frame in which is mounted an abrasive means such a file, rasp or honing stone. A supporting platform, on which is mounted a pushing block and a handle, is slidably mounted in the frame. The object to be dressed is placed on the supporting platform, both of which can then be moved back and forth with one hand by the user, while the other hand pushes the object against the abrasive surface. The angle of the supporting platform in relation to the abrasive means can be made adjustable by means of a portion of the supporting platform comprising an angle-control supporting portion that is pivotally attached along one side of a base portion of the platform, the pivotal attachment being on the side of the platform adjacent to the abrasive means.
