  • Patent number: 10710122
    Abstract: Scrapers for removing adhered material from surfaces employ continuous and discontinuous material removal edges to remove different types of material. Continuous and sometimes discontinuous material removal edges are constructed and arranged to conform to the curvature of a surface from which material is to be removed, when a user forces the scraper against the surface. Some scrapers include multiple material removal edges designed to simultaneously contact the surface. The use of multiple points of contact combined with locations of handles provide stable designs that reduce hand and wrist strain.

  • Patent number: 7103936
    Abstract: A wood scraper having two oppositely angled blades on a single head, and preferably two heads with two oppositely angled blades on each head. Thus, on both the forward and reverse stroke, there are two spaced apart blades scraping the work piece. This covers twice the surface area with the same effort as a single-bladed or single-headed scraper. All the blades are rigid and have a straight edge. All the blade edges are aligned with the planar surface of the work piece. This produces a level cut and makes the tool more stable, making gouging unlikely and enhancing the efficiency of the scraping action. The tool can be operated easily with one hand. In addition, the use of straight blades allows all the blades to be sharpened easily and quickly and at the same time using a belt sander or on a sheet of emery paper on a flat surface.
