ABSTRACT:
A hand-actuated scissors useable by an individual whose hands and fingers are weak or impaired and therefore experience difficulty in operating a conventional scissors. The scissors include a pair of blades whose cutting edges face each other, the blades being joined by a swivel pin whereby in an open state of the scissors the blades are angled with respect to each other. When the scissors are put into a closed state, the blades are then brought together to effect a cutting action. The handle sections of the blades which extend beyond the swivel pin are so shaped that in the open state the ends of these sections are widely spaced apart. Bridging the ends of the handle sections is a yoke defined by a saddle-shaped plate of resilient material forming a spring-loaded grip which normally maintain the scissors in an open state. When the grip is nested in the palm of a user's hand and grasped, the user by squeezing the grip with his or her hand can then bring the ends of the handle sections closer together, causing the scissors to assume a closed state to effect a cutting action. When pressure on the grip is released, the scissors automatically return to the open state preparatory to the next cutting action.
