Abstract
A composite fishing rod is described having a polygonal exterior with an integral interior spine which attaches to the interior of the joints or facets of the polygonal exterior. The polygonal exterior and spine are formed in one homogeneous structure, wherein gluing or other attachment is not required after forming the rod section. The fishing rod provides a high strength to weight ratio with improved flexibility, durability and action when compared with rods of conventional construction. The invention describes alternative embodiments for fabrication and novel joining ferrules, reel seat, line guide and other accessories directed toward enhanced utility.
