Abstract
Typically a limb for an archery bow has a butt section or end attachable to a bow riser, a middle or hinge section and an opposing tip section or end. In a preferred embodiment, the present method and limb includes a rib section formed in the middle or hinge portion of the limb. This allows a narrowed front-profile to be presented in the hinge section, while maintaining the total cross-sectional area. In one preferred method, at least one half of a mold is formed to define a rib section in the hinge section of the limb. Preferably the rib section runs longitudinally along the length of the hinge section, and may include a tapered profile along the edges and ends of the rib.
