ABSTRACT:
A shear-type nail clipper that includes a base arm (1), a twisted arm (13), a stud (15) and an actuating lever arm (17) is disclosed. The base and twisted arms are joined together at one end; and, concave blades (25, 37) are formed in the other ends of these arms. The cutting edge of the blades face one another and lie generally orthogonal to the longitudinal axes of the base and twisted arms. The twisted arm is twisted such that its blade (37) is transveresly inclined with respect to the blade formed in the base arm. As a result, the gap between the blades varies from one side to the other. Formed in the edges of the base and twisted arms adajcent the narrow gap side of the blades are aligned flcrum protrusions (27, 35). Formed in the edge of the base and twisted arms adjacent to the wide gap side of the blades are stud flanges (23, 34). The stud (15) is mounted in holes located in the stud flanges and extends beyond th outer surface of the twisted arm. The lever arm (17) is mounted on the outer extension of the stud (15). When the lever arm is suitably oriented and manually moved toward the twisted arm, the blade end of the twisted arm is rotated toward the base arm. The apex of rotation is the point where the fulcrum protrusions meet. The end result is a shear-type cutting action, rather than a chop-type cutting action.
