ABSTRACT:
A ferrule joint for a fishing rod blank made from joining plural flexible tapered resin shafts having hollow cores disclosed. The ferrule joint comprises a ferrule integral with one end of a first shaft. The ferrule has a tapered bore extending inwardly from the end of the first shaft. The hollow core end of a second shaft is insertable into the bore to frictionally interlock the shafts together. A transition section integral with the first shaft has a tapered bore joining the tapered bore in the ferrule to the hollow core of the first shaft. The tapered bore in the ferrule and the tapered bore in the transition sections are formed from plural overlapping patterns of fiber reinforced resins superimposed on the first shaft around the hollow core.
