ABSTRACT:
Tool attachments and extensions handles may be removably connected to each other. In an example embodiment, a tool attachment is capable of being connected to an extension handle having an extension handle connector, which includes a first field emission structure. The tool attachment has a tool implement and a tool attachment connector, which includes a second field emission structure. The tool attachment connector is adapted to be mated to the extension handle connector with the second field emission structure in proximity to the first field emission structure such that the first and second field emission structures have a predetermined alignment with respect to one another. Each of the first and second field emission structures include multiple Field emission sources having positions and polarities relating to a predefined spatial force function that corresponds to the predetermined alignment of the first and second field emission structures within a field domain.
