I haven't been able to find much information about this old set of Craftsman pliers. I think the handles were an optional upgrade from Sears. The only mark other than Craftsman and Made in USA is a "C" (without a circle around it) on the reverse side. I remember my dad having a pair of needle nose pliers with similar see-thru plastic grips. I'm wondering now if they were Craftsman. Does anyone have knowledge of these old pliers? I suppose they're a lineman pliers, but the jaws don't close all the way and leave an opening the thickness of a matchbook. The cutting part closes all the way. I have not run into these before, so I thought I'd share.
