I didn't have these three so decided to keep them. Top is Japan and has a hole in the front and also the side and as I remember made for the single wire clip on auto water hoses. Middle is a Utica level jaw (I have several Sargent level jaw pliers and the original Bernard type but had never seen a similar Utica). Bottom is a no name but nicely made with a different type of slide for the slip joint----anyone know who might have made it?
