Abstract
Abstract A TUNGSTEN CARBIDE SMALL SPIKE IS ENCLOSED AND SECURED IN A METAL JACKET OF SOFTER AND LESS HARD MATERIAL THAN THE SPIKE BUT WITH THE SPIKE PROJECTING OUT OF THE JACKET. THIS JACKET HAS AN EXTERNALLY THREADED UPPER END PORTION FOR RECEPTION IN THE USUAL INTERNALLY THREADED METAL INSERT COMMONLY FOUND IN GOLF SHOES. A USUAL DISHED FLANGE AROUND A MID-PORTION OF SAID JACKET LIMITS THE DEGREE TO WHICH THE JACKET THREADED UPPER END CAN BE INSERTED INTO AN INSERT IN A USUAL GOLF SHOE.
