Tool and Method for Applying Torque

A tool for applying torque to a maneuvered object, such as for example a screw head or nut, comprising:

• a grip comprising at least a first jaw, and at least a second jaw where the first jaw and the second jaw are connected to at least one lever (arm), wherein characterized in that at least one of the jaws include at least one recess comprising a first contact surface and a second contact surface, wherein at least one of the first or second contact surfaces is arch-shaped with the depth of the recess between about 0.1 and about 0.6 of the width of the contact surfaces as measured at the extension of the contact surfaces, and the radius of the arch-shapes between about 0.3 and about 1.5 of the depth of the recess, and wherein the arched shape provides a mechanical equilibrium of vectors contributing to prevent the tendency of said object to escape from the grip, the first and second contact surfaces of the first jaw and the second jaw making contact with the maneuvered object, such as for example a screw head or nut, when applying torque to the maneuvered object.
