ABSTRACT:
Handtools, typically two screwdrivers with a slotted tip (14) and a crossheaded (Phillips) tip (24), respectively nest together for pocket storage in one compact package without any protruding points or tips. Tip (14) is attached to blade (or shaft) (12) that mounts on handle (or body) (10). Tip (or bit or head) (24) is attached to blade (22) that mounts on handle (20). For storage, the two handtools are placed in opposition and brought together to mate hermaphroditically, with blade (12) entering bore (or hole) (16) in handle (20) and blade (22) entering bore (16) in handle (10). When so nested, both blades and tips are completely covered to protect the user's clothing when stored in a pocket. The resulting package is approximately the same length as a single tool and has the same diameter, yet is easily pulled apart so that both tools become fully usable separately.
