DEFINITION

Classification: 30/237

(under subclass 194) Shears in which the blades move relatively, other than in simple pivoting or straight line reciprocating movement, during the cutting operation. This is usually for the purpose of giving the shears a draw cut. Where the pivot is offset for the same purpose, see this class subclass 259.
