ABSTRACT:
A cutting implement such as of the scissors type is disclosed herein, having a pair of elongated shanks pivoted together midway between their opposite ends so that opposing blade cutting edges converge together as the shanks are closed towards one another. The cutting edges are carried on an exposed edge marginal region of either permanent or replaceable blades disposed into open receptacles on the respective shanks. Each shank receptacle is defined by sloping surfaces at the opposite ends of each receptacle and a pair of stepped posts is provided in spaced apart relationship between the opposite opening ends. A replaceable blade is formed with a plurality of recesses along the edge opposite to the cutting edge leading into longitudinal slots whereby the shank posts are indexed or registered with the blade recesses for snap-lock retention therewith into the slots with the blade seated on the post steps. A permanent blade is provided with shaped holes for placement on the steps of the posts. A cover having shaped holes is placed on the step of the posts and between the opposite shaped ends of the recess. The cover is welded at the ends to the shank and to the posts. The replaceable blade may be composed of spring steel while the permanent blade may be of ceramic composition.
