  • Patent number: 3987542
    Abstract: Improved angular shear or scissors comprising two mated scissor elements, each of which comprises a blade section, a shank section and a handle section, said elements being pivotally-united at a position between said blade and shank sections whereby said blade sections cooperate to provide a cutting action when said handle sections are manipulated. The invention is characterized by each of said blade sections being relatively flat and being upwardly inclined at an angle of at least about 20.degree. from its shank section and the lower blade preferably being longer than the upper blade and being provided with a relatively narrow tip which is pointed for piercing purposes.
