DEFINITION

Classification: 81/302

(under subclass 300) Tools including at least two jaws, each of which has a work-engaging surface facing away, oppositely, from the other jaw, and in which the movement of the handles towards each other effects movement of the jaws away from each other whereby the jaw surfaces engage interior surfaces of the work.

(1) Note. Jaws which have outwardly-facing work-engaging surfaces, which jaws move towards each other as the handles are moved together, are classified in other subclasses on the basis of features other than the facing of the work-engaging jaw portions.
