A kinda cool set of old pliers here. I got them from the fall MVWC auction last year. They have pointy tips, I think for wrapping wire??? And a hex nut opening between the handles. They also have steel wire-cutter inserts dovetailed into each jaw, which hopefully you can see in the second photo. The fit is perfect.
Each handle is stamped A.L. Barth, on both sides of the tool. (So four times altogether.) But who the heck was A.L. Barth?
