  • Patent number: 7752703
    Abstract: The present invention is a type of hand tool apparatus for use as a trowel, scrapper, spatula and others. The tool comprises a handle, to which a plate member is securely coupled. A blade member is securely attached to the plate member; the blade member having opposing parallel edges of typically unlike configurations. The handle has a locking device that is pressure sensitive and provides a means to immobilize the pivot mechanism and secure and lock in place the blade member. Activated by the user, such as finger/thumb manipulation, disengagement and release of the locking device allows the pivot mechanism to operate and the blade member to rotate from the first blade edge to the second blade edge. The new method and novel tool allows for achieving a consistently uniform layer of compound spread much more rapidly and with a reduction of material waste and reduces the need for two or more tools needed in task succession.
