Over the course of fly fishing history there have been many advancements in the tackle that angler's use. The original fly rods were nothing more that refined tree branches with a piece of string tied to the top. By the early part of the 19th century rod makers began experimenting with bamboo as a possible rod making material. By the latter part of the century rod makers were splitting sections of cane and producing the first modern fly rod. A reel seat was added to the butt of the rod, a grip of cork was added just ahead of the reel seat, and guides of fine wire were wrapped to the shaft and metal ferrules allowed the sections of the rod to fit together snuggly. The modern fly rod was born.
