ABSTRACT:
A tool, such as tweezers or scissors, having articulated opposing jaws is disclosed. The tool comprises a handle having first and second opposing arms projecting from a section by which the arms are joined, the arms being normally spaced throughout their length and being resiliently flexible toward each other. Each arm includes an elongate cavity extending longitudinally thereof and having an opening at the end of the arm. Jaw inserts are provided, and each has a working end for manipulating or cutting an object and an elongate shank that is received by one of the cavities to secure the jaw insert to its respective arm. The tool further includes a mechanism for guiding each working end in a single plane of movement with respect to the opposing arm upon flexing of the arms toward each other to substantially avoid undesirable lateral flexing of the opposing working ends with respect to each other.
