An archery bow where the individual limbs can be independently tuned at an area where they connect with top and bottom portions of the handle. The tuning is coupled with a connection structure which lengthens the moment arm that had heretofore been used in connecting limbs to the bow's handle to reduce the amount of force required to hold the bow in a drawn, cocked position and alter the force profile along the stroke of the draw by increasing the force administered to the arrow on release of the string.

An archery recurve bow having a handle and riser section which is substantially rigid, the risers supporting upper and lower limbs pivotally mounted thereto by means of guide plates which sandwich the limbs therebetween. Each limb has a tip which interconnects the limbs by means of a drawstring and tension cables are connected such that one cable extends from a butt end of one limb, remote from its tip, to the other limb between the pivot point at its tip. Conversely, the other cable is similarly connected from the butt end of the limb to its counterpart limb between the pivot point and the tip.
