A modular tool body having upper and lower sections, a pair of longitudinal members define a central open region, the longitudinal members joined at one end having a lifting feature formed therein configured to accept a manipulator. The lifting feature is positioned such that when the modular tool body and a rig tool connected thereto are lifted by the manipulator, they are easily moved over, aligned with, and connected with a working drillpipe or other rig tool while minimizing possibility of the manipulator slipping off. The lower section includes a threaded end mating with a mating end of a rig tool, a central longitudinal bore, and an upper end formed to accept the lower ends of the longitudinal members of the upper section. Elongate slots in each longitudinal member define one or more manipulating handles. A pair of generally horizontal hand holds may be formed in each longitudinal member.
