stable manipulation thereof the stationary member 16 is stiff and substantially thicker than the longitudinal body 12 and includes concave sides 40 both features to facilitate stable handling by a user the stationary member 16 is preferably rounded and more preferably defines a diameter d that extends parallel to the wire axis aw of the mounting wire 32 the stationary member 16 is preferably laterally offset to one side of the longitudinal body 12 in a preferred embodiment the longitudinal body 12 extends substantially along a tangent to an outer circumference to the rounded stationary member 16 of the handle the trigger 18 is preferably the same thickness as the stationary member and preferably extends as a continuation of the outer circumference as such the stationary member and the trigger together assume a substantial area of a closed rounded shape such as a circle or oval the trigger is substantially stiff and preferably not subject to deformation as it is rotated about the hinge axis the trigger 18 includes a first end 43 and a free second end 45 the first end 43 of the trigger 18 is connected to the stationary member 16 by a living hinge 44 and is located adjacent the proximal end 22 of the longitudinal body 12 the living hinge 44 is located spaced apart from the wire axis a of the wire 32 and is fixed in location as the trigger 18 is rotated on its hinge axis ah relative to the stationary member 16 the hinge axis ah is oriented orthogonal to the wire axis aw and is located at one side of said wire axis whereas the trigger 18 can.
