An easy package lifting tool designed to allow a user to manually lift a package with one hand directly over the package's center of gravity that uses the weight of the package to exert inward directed forces by two gripping jaws on opposing sides of the package. The tool includes two pads pivotally attached to the distal ends of two main arms. The two main arms cross and are pivotally attached together vertically above the center axis of a line that extends between the two pads. Attached to the proximal end of the first main arm is a secondary arm. Pivotally attached to the proximal end of the second main arm is a lift arm. The distal end of the lift arm is pivotally attached to the secondary arm. Formed on the proximal end of the lift arm is a curved handle section. The location of the second pivot point between the secondary arm and the lift arm is offset from the first pivot point and the center axis of the two grippingpads. By aligning the curved handle section directly over the center axis and by using the weight of the package to generate the force needed to grasp the package, large packages are easy to lift without injury.
