Abstract: A fishing rod assembly with interchangeable handle components permits different reels, different counterweights or counterweight amounts, and even different rod blank assemblies, to be assembled and used interchangeably with one another for different types of fishing (fly casting, spinning, trolling, etc.) as desired. The handle assembly includes a threaded sleeve which is used to secure various collars and different types of reels thereto. A finger grip or trigger may be installed using these components to provide better casting for certain types of fishing. The rod blank passes through a closely fitting axial passage through the handle assembly, with the butt end of the rod blank assembly protruding slightly from the butt end of the handle assembly.
