Patent ID: 8418519

Claim:
A hand tool comprising first and second handles and jaws, where the jaws are operated by squeezing the handles together, wherein an anti-slip device is arranged on the outer side of a distal end of the first tool handle, the first tool handle has a hard surface with low friction enabling the user's fingers to slide on the surface of the first tool handle, and the anti-slip device is arranged to bear on a support surface in order for a user, with the use of one hand, to be able to press the second tool handle against the first tool handle in a controlled manner using a force (F) in excess of hand force; and wherein the anti-slip device is made of a high friction material; wherein the hand tool further comprises crimping dies movable relative to one another and arranged on the jaws, the crimping dies being arranged to be brought together when the handles are pressed together in order to crimp a workpiece between the dies; wherein the hand tool further comprises a body, and wherein the first handle is a lower handle which the user's fingers grip when pressing the handles together, the lower handle comprises the anti-slip device and the hard surface with low friction in order for the fingers to be able to slide on the handle surface as effortless as possible, thus maximizing the force of the user's hand grip and the efficiency of the hand tool when pressing the handles together using one hand, and the second handle is an upper handle and the second handle is integrated to the body; wherein the upper handle has a non-slip covering in order to have an anti-slip effect to the user's palm and to minimize discomfort and cushion the user's grip when squeezing the lower and upper handles together; and wherein the handles are not symmetric with respect to each other, the lower handle has a length, and at least a portion of the anti-slip device at the outer side of the distal end is spaced apart from the jaws by at least the length of the lower handle, the anti-slip device is softer than the hard surface of the lower handle, and the hard surface of the lower handle provides less friction than the non-slip covering of the upper handle.
