ABSTRACT:
An improved cutting tool, such as scissors, shears, and the like, having two cooperating members that are interconnected so as to be pivotally movable, with respect to each other and about a connection point, between an open position and a closed position. The members each have a handle at their one end, a shank portion disposed between the handle and the connection point, and a blade portion disposed between the connection point and their other end. Each of the shank portions have an inside face, an outside face, and a leading edge that faces the other leading edge when the members are in their open position. A bearing ramp is formed on the inside face of one of the shank portions and has a first end adjacent the leading edge of the one shank portion and a second end away from the leading edge. The ramp projects from and above the surface of the inside face a distance that gradually increases between the first end and the second end, and is adapted to contact the inside face of the other shank portion so that, as the cooperating members are moved from their open position to their closed position, the other shank portion gradually climbs up the ramp.
