A crimp cover closing tool is provided with a pair of curved force transmitting members joined at a fulcrum and forming opposed jaws. The jaws each have an angularly offset tip with interiorly disposed opposable spherical forming surfaces, a radius of curvature of about 2.1 mm and a depth of about 1.5 mm. The overall length of the tool is about 130 mm. The opposable spherical forming surfaces are spaced from the fulcrum by a distance of at least 30 mm. The tip of the forming tool has an angle of offset of about 30°.
