Claim:
A two part scraping tool for scraping a free standing substrate by sandwiching the free standing substrate between the two parts of the scraping tool such that one of the two parts slides along and scrapes an exposed surface of the free standing substrate, the two part scraping tool comprising: a scraping member for sliding along and scraping the exposed surface of the free standing substrate, comprising a scraping body further comprising a scraping blade having a cutting edge disposed substantially along at least one side of said scraping blade, a separate generally rigid blade holder which is disposed to cooperatively receive and retain said scraping blade in fixed relation thereto, and which said generally rigid blade holder is mountable to said scraping body, a removable fastener disposed to couple said generally rigid blade holder to said scraping body; and a first magnetically responsive member mounted to said scraping body; and a handle member comprising a handle body and a second magnetically responsive member mounted to said handle body; wherein when said handle member and said scraping member are placed in a deployed position said scraping blade is positioned on one side of the free standing substrate in scraping relation to the free standing substrate, and said handle member is placed on the opposed side of the free standing substrate such that said first magnetically responsive member magnetically attracts and retains said second magnetically responsive member against the free standing substrate with said handle member and said scraping member remaining in mutual opposition and in mutual proximity even when said handle member is pulled along the free standing substrate, wherein at least one of said first magnetically responsive member and said second magnetically responsive member comprises a permanent magnet, wherein said scrapping member includes a steel plate, and said handle member includes a steel plate, wherein said steel plates of the scrapping member and handle member ensure mutual magnetic attraction between the handle member and the scrapping member.
