  • Patent number: 7168178
    Abstract: A measuring device having a longitudinally extending polymer portion and a longitudinally extending metal portion secured to the polymer portion. The polymer portion may be molded over one longitudinal edge of the metal portion to thereby permanently secure the portions together. The measuring device may have a longitudinal balance axis disposed between a free edge of the metal portion and a free edge of the polymer portion. The balance axis can be disposed so that when the measuring device is placed on a page the metal portion free edge will contact the page and the polymer portion free edge will be raised. Alternatively, the balance axis can be disposed so that when the measuring device is placed on a page the metal portion free edge and the polymer portion free edge are raised above the page. Pressure on the metal portion will cause the metal portion free edge to contact the page while pressure on the polymer portion free edge will raise the metal portion free edge further off the page.
