DEFINITION

Classification: 606/174

Shear type (e.g., scissors, etc.):

(under subclass 167) Subject matter wherein the cutting is accomplished by the action of two cutting blades which when moved toward each other about a fixed pivot point cooperate to effect a cut.

(1) Note. Patents in this subclass are limited to scissors-type cutters which typically begin their cut at the edge of a surface and continue their cutting action into the interior of the surface as desired.

(2) Note. Punching devices which disclose a (1) punch and a cooperating die or a (2) punch and a cooperating anvil surface are not considered shears since their cut is made for the purpose of making a generally circular type of incision

in a surface, usually at some distance from a peripheral edge of that surface.
