Dynamite Tool currently has the Channellock 350S 9-Inch Ironworkers Plier with Spring for $19.50.
The 350S is designed mainly for working with rebar tie wires (baling wire!). The hook at the end of the handle is a stop for the hand and allows pulling with greater force when tightening the wire. We never thought about the lack of a return spring on other pliers of this size, but it does make the repetitive opening and closing of pliers much easier. They are also available on Amazon for $20.50 and eligible for Super Saver shipping so that may be a better deal if you’re ordering other stuff.
