ABSTRACT:
A scissors which may be utilized by persons having weakened hand muscles is disclosed. The scissors comprises first and second blade elements. Each of the blade elements includes a front portion having a sharp cutting edge, a middle portion and a rear portion. The blade elements are pivotally mounted at the rear portions thereof and biased by a spring member towards the open position of the scissors. First and second handles are attached to the middle portions of the first and second blade elements, respectively. The handles increase the effective widths of the middle portions of the blade elements thereby increasing the mechanical advantage of the scissors. This permits a user of the scissors to close the scissors with a smaller force.
