ABSTRACT:
A tool for use in the installation and removal of golf spikes from the sole of a golf shoe. The golf spikes are of the type made of plastic and having a ground-engaging surface. Projections are formed on this surface, defining a variety of patterns such as a spiral pattern consisting of a plurality of curvilinear ridge portions extending radially outwardly from the center of the spike to the outer edge thereof. A plurality of rills are formed in the spike surface with a rill located between each pair of adjacent ridge portions. The tool comprises a head portion and a concave recessed surface defined by the head portion for engagement with the ground engaging surface of the spike. The recessed surface of the tool defines a plurality of spaced-apart projections dimensioned to be received within the spike rills, and a plurality of curvilinear recesses with each recess being located between each pair of adjacent projections. Each recess is dimensioned to receive one of the spike ridges. Upon rotation of the tool, a spike may be installed in or removed from a golf shoe. Alternatively, a tool having two sets of projections extending from the periphery of the tool is employed. Both types of projections, which are in alternating positions, extend short of the tool center and one set is shorter than the other whereby use with a large variety of plastic spike designs is possible.
