发明名称 CYLINDRICAL GOLF CLUB
摘要 <p>A golf club having a cylindrical body (12) with a first end (14), a second end (16) and a centroid-located shaft bore (22). Into the first end (14) is inserted a putting insert (34) or a driving insert (74), and into the second end (16) is inserted respectively a putting-practice insert (42) or a second, non-striking insert (76). At the centroid of the cylindrical cylinder (12) is inserted a shaft attachment insert (26) having a shaft cavity (28) that is in alignment with the shaft bore (22) located on the cylindrical body (12). Into the shaft bore (22) and the shaft cavity (28) is inserted and attached a shaft (50) that is angled outward when using the driving insert (74). The circular cross-section of the putting insert (32) produces a larger "sweet spot". Therefore, if the golf ball is struck off-center, the deviation from a projected staight line is minimized.</p>
