This antique pair of Pliers is marked GRONK. They measure approx. 6 ½ inches long. They have a inside grip area and a wire cutting section. The end of one handle is screw driver shaped. I found “The Gronk Hanger Co., of Havana, manufacturers of pliers. Established in 1886” and Havana is now called Montour Falls. I was unable to find any on a search. They are well used with rust and wear in good collectible or usable condition.
