Abstract
The present invention is directed to a shaft and arrow system. The shaft and arrow system includes a hybrid structure that may include two concentric tubes. A first of the two concentric tubes may comprise an outer shell or jacket of thin-walled metal alloy. A second of the two concentric tubes may include an inner core of thin-walled fiber reinforced polymer. The two concentric tubes may be bonded together by a suitable adhesive such as epoxy or urethane. The shaft may have a reduced diameter as compared to conventional arrow shafts, and the shaft may be receptive of a variety of inserts, points, nocks, and other components. Some inserts may be completely recessed within a first end of the shaft.
