Abstract
According to one embodiment, a bow includes a handle portion and a bowstring. Compression members including primary compression elements and secondary compression elements are positioned on the ends of the handle portion. The compression elements are arcuate in shape and joined at the ends. As the bowstring is drawn, the compression members are compressed and energy is stored therein. The bow can include limbs that do not significantly deform or store energy as the bow is drawn. Upon release of the bowstring, the stored energy is rapidly returned to the bowstring.
