  • Patent number: 10611010
    Abstract: A sliding center of gravity hammer is disclosed herein allows the user to slide a heavy weight to various positions in the barrel of the hammer for different applications. When more force is needed to drive a nail, the heavy weight could be locked in the first position which is closest to the hammer head. When less force is needed, the heavy weight could be locked in the third position which is closest to the handle end. The embodiment allows the user to adjust the weight of the hammer to the user's needs when working on many different applications which increases the operation efficiency and reduces risk of injury to the user.

  • Patent number: 6792831
    Abstract: The tools (wrenches) of this invention provide a one color instant identification of color coded tools. Preferably, the tools have a portion of their outer surface colored. Typically, the color impregnates the metal or plating during the manufacturing process. Another embodiment is a colored applique, band or sleeve on the outer surface of the tools. The key of this coloring is to identify the tool quickly by coloring a large area of the tool. This provides for quick identification of the tool even if the numerical designations are illegible because of small sizing or dirt obliteration. In a preferred embodiment, virtually the entire tool is colored during manufacturing. In another preferred embodiment, large raised numbers combine with the overall color scheme to make the tools quickly identifiable. Dirting the large colored surface is very unlikely as is obliterating the large raised fractional numbers.
