Abstract

Pinking scissors having replaceable cutting blades. The replaceable cutting blades have different edges to provide different types of pinking designs such as scallops, triangular sections, rectangular edges and the like. The replaceable blades are of rigid L-shaped construction one side serving as a base fitting against the supporting stem of the scissors and the other side having a cutting edge. Stop means are provided for registry on the supporting stems which are bifurcated and spaced apart to provide for easy reception of the replaceable blades. A special feature resides in the provision of a reversible cutting blade with both edges of the L-shaped sections having a pinking cutting edge. When not in use one section with the pinking edge serves as a base and when desired to provide a different design the blade may be removed and reversed with the unused portion serving as cutting edge and the section previously serving as a cutting edge used as a base fitting against the support stems.

Dependent claims

Pinking scissors having replaceable blades for cutting multiple designs on the edge of sheet material, said scissors comprising a pair of pivotally connected cutting blade support stems provided with handle portions, means for attaching a reversible cutting blade to each of said stems, each of said blades being comprised of a first blade member connected at right angles to a second blade member to form a reversible cutting blade, said blade being supportable upon said stem with a first one of said blades acting as a base section and being secured in flush relation to an inner surface of the stem and a second of the blades extending at right angles thereto in cutting relation with a mating reversible cutting blade supported on the other support stem, the serrated edges of the first blade members carried by each stem meshing with each other to form a first serrated design, and said blades being reversible to present the second blades in cutting relation and the first blades acting as a base and being securable on the stems to provide a different serrated cutting pattern with the second blades.
