Abstract
Hand held fluid operated shears comprises first and second blades. The blades are pivotally connected for movement of one relative to the other about an axis. The shears include a thumb-receiving handle and a finger-receiving handle. One of the handles is supported for pivoting about the axis independently of both blades. The other handle is fixed relative to the first blade. A fluid actuator is coupled between the fixed handle and the second blade. A fluid operated servo mechanism is controlled by the second blade and the pivoted handle to control operation of the fluid actuator to move the second blade relative to the first blade in coordination with the movement of the pivoted handle. The rate of movement of the second blade decreases relative to the rate of movement of the pivoted handle as the second blade moves from an open position at an acute angle relative to the first blade to a closed position where it overlies the first blade.
