Abstract
A pinking shears having a pair of blades pivotally connected together by a bolt and having cooperative teeth formed along their leading edges and having handles at the ends of the blades opposite said teeth. A non-metallic spacer and pressure producing ridge member is located between the blades and has an apertured spacer portion through which the bolt extends and which serves to provide rough blade separation. The member also has a pressure producing ridge located at the handle side of said bolt and for bearing against the blades to produce cutting pressure between the teeth of the blades. The blades have tapered leads which cooperate with one another as the shears are closed to provide gradual smooth engagement of the blades. Each of the blades also has an alignment land located outwardly in respect to the bolt and the tapered leads, the alignment lands abutting against one another when the shears are closed and the opposed teeth are brought into initial contact with one another to provide exact positioning of the blades and ensuring smooth engagement of the teeth with one another. One of the teeth of one of the blades located nearest the bolt has a cut-away relief portion to provide smooth engagement of the teeth.
