Abstract:

A shearing apparatus comprising an index portion and a thumb portion that are pivotable relative to one another about a pivot mechanism. One of the thumb blade and index blade is provided with a serrated portion, while the other of the index blade and the thumb blade is provided with a cutting edge, such that the serrated portion and the cutting edge cooperate with one another during the relative pivoting movement of the index portion and the thumb portion to carry out a shearing or severing action. The shearing apparatus can alternatively comprise a single blade portion, pulled by a handle, and provided with a serrated portion. In both embodiments, the serrated portion has a configuration that presents a compound angle, which comprises a cutting edge angle and an angle relative to the longitudinal direction.
