Abstract
Shears have two crossed pivotally interconnected levers, each having a blade end and a handle end, and normally biased open. Upper and lower handles are, respectively, connected to the handle ends of the levers, the upper handle having a low-friction outer surface and including front, rear and medial portions, while the lower handle has a high-friction outer surface with a downwardly convex lower portion. The front portion of the upper handle projects upwardly to stop forward movement of the hand. The medial portion is of reduced cross section to facilitate hooking of the user's thumb thereover. The rear portion has a laterally upwardly and inwardly sloping upper surface. An elastomeric loop depends from the lower handle rearwardly of the front portion of the upper handle and receives therethrough only the middle finger of the user's hand.
