ABSTRACT:
An improved knife system provides for construction of wear-resistant precise coaxial alignment of pivots connecting "U"-section handle pairs to blade such that a recess in the blade can coact with a handle edge in heavy duty wirestripping without loosening the blade-to-handle pivots. In folding each of the "U"-shaped handles during construction the usual slight misalignments of blade-pivot holes in the two legs of the "U"-section of the handle caused by walking of the tapered handle blank being folded about a centerline between the blade-pivot holes, are avoided. First and second sets of holes are punched in spaced relation along the centerline at the same time as the blade pivot holes cause the handle bending to be precisely symmetrical about the centerline. The sets of holes also serve as drainage holes and provide non-slip grip for the user's hand as well as serving as plier-jaw grips, when desired, as well as providing for wirestripping to be the same in either direction, termed "symmetrical wirestripping".
