  • Patent number: 8523638
    Abstract: A scraper in combination with a sharpener provides consistent sharpening of the scraper blade. The scraper has a scraper blade, blade holder, and bearing surface. The sharpener has a sharpening element and a guide generally parallel to the sharpening element. The bearing surface of the scraper fits the guide of the sharpener and the scraper blade contacts the sharpening element. The scraper can be drawn along the guide to draw the blade along the sharpening element. The bearing surface and guide keep the blade in consistent and correct relation to the sharpening element to provide proper sharpening of the scraper blade. Adaptors may be used to sharpen additional types of blades or tools on the sharpener and different types of sharpening elements may be used in the sharpener.

  • Publication number: 20110201261
    Abstract: A scraper has a blade holder that tapers from a wider width to a narrower width. A blade with a scraping edge is mounted on the blade holder with the scraping edge near to the narrower width of the blade holder. The blade is interchangeably mounted and can be replaced with other blades. The blades can have different widths for their scraping edges. The tapered shape of the blade holder allows blades with different widths of scraping edges to be used in the scraper without the blade holder interfering with the use of the scraper. Embodiments of the scraper have handles which may have features such as a hand rest near the blade holder to provide additional pressure and a ring at the end of the handle to provide additional pull. At least one embodiment of the scraper has a bearing surface to fit on a guide on a sharpener.
