ABSTRACT:
A specialty hand tool primarily for removing upholstery trim buttons from their spring steel retainers in an efficient and effective manner without destroying the ability of the retainers to be reused immediately. The tool has two elongated members pivotally mounted to each other in a general plier configuration. One of the opposing jaw members of the tool has a substantially flat surface with a dimple therein for engaging the apex of the trim button stud. The second jaw member is bifurcated into two, free-standing portions which straddle the shaft of the trim button stud. The second jaw members has first and second generally U-shaped edges of different sizes which are spaced from each other with the larger of the two edges being positioned closer to the first jaw member. An inclined surface extends between the two U-shaped edges giving the second jaw member an overall appearance of a horseshoe-shaped or open-ended sport's arena when viewed head on. The second jaw member also includes serrated sections, diverging edges, wedge-shaped ends on each of the bifurcated portions, and a distinctive neck portion so that the bifurcated portions can be inserted between the back of the trim button and the underside of the retainer without any interference from the rim portion of the retainer.
