Abstract
A scissors with interchangeable blades wherein first and second blade holders are pivoted with respect to each other and each has a manual graspable configuration thereon. On the other end of each blade holder is a blade retainer. Individual blades can be placed in pairs in these blade holders. These pairs of blades have different cooperative configuration so that they can make triangular cuts of different sizes, scallops of different sizes, and other repeating configurations.
Claims23
A scissors comprising:
- first and second blade holders, said first and second blade holders being pivoted with respect to each other on a pivot axis;
- manually graspable means on each of said first and second blade holders so that said first and second blade holders can be rotated with respect to each other around axis;
- first and second blade retaining means respectively on said first and second blade holders, and further including a recess in said first blade holder for releaseably retaining said first blade therein and said second blade holder has a recess for releaseably retaining said second blade therein and wherein each of said recess has a rabbeted notch in each end thereof and each said blade has a finger thereon sized to fit within its rabbeted notch so that said blade is held in said blade holder so that it cannot be moved away from said back wall of said recess;
- and
- first and second shear blades respectively releasably mounted in said blade retaining means, said first and second shear blades being selected from a plurality of pairs of shear blades, each configured to shear a different configuration in sheet material.

A scissors comprising:
- first and second blade holders, and wherein each said blade holder has a pair of notches therein and each said blade has a pair of finders for engaging in said notches, said notches preventing withdrawal of each said blade from its retaining recess except in a direction at a right angle to said blade surface;
- pivot means interengaging said first and second blade holders so that said first and second blade holders rotate with respect to each other on a pivot axis;
- first and second manually engageable means respectively on said first and second blade holders for relative rotation of said first and second blade holders around said pivot axis;
- first and second mounting means respectively on said first and second blade holders for detachably holding first and second shear blades respectively, said shear blades each having a shearing face and having contiguous faces which interact when the first and second blades are moved past each other to cut a non-straight line in sheet material.
