1. An apparatus for remotely gripping or cutting an object, the apparatus comprising:

  • a first handle pivotally connected to a second handle for relative motion in a common plane, said first and second handles being adapted for orientation in a minimal relative angular position and for orientation in a maximal relative angular position;

    a first link having first and second ends, said first end of said first link being pivotally connected to said first handle and said second end of said first link being adapted for linear reciprocating motion in responsive association with relative motion of said first and second handles between said minimal and maximal relative angular positions;

    a slider pivotally connected to said second end of said first link, said slider being adapted for linear reciprocating motion in responsive association with relative motion of said first and second handles between said minimal and maximal relative angular positions;

    a cylindrical extension extending substantially coaxially with respect to said linear reciprocating motion, said cylindrical extension having a proximal end being supported for relative rotation around said slider and having a distal end with respect to said first and second handles;

    a drag mechanism supported with respect to said cylindrical extension, said drag mechanism being adapted for providing a selected limited resistance to free relative rotation of said cylindrical extension with respect to said slider; and

    a first jaw pivotally connected with respect to a second jaw, said first jaw being supported with respect to said distal end of said cylindrical extension, said second jaw having an actuated arm and an actuating arm and having the pivotal connection with respect to said first jaw being interposed between said actuated and actuating arms, said actuating arm being pivotally connected with respect to said slider;

    wherein the object is engaged by said actuated arm of said second jaw being pivoted toward said first jaw in responsive association with said linear reciprocating motion of said slider as said first and second handles are reoriented from said maximal relative angular position to said minimal relative angular position.
