These heavy-duty pliers feature one flat jaw and one half-round jaw and a compound box joint that keeps the jaws parallel as they open and close; the joint creates even pressure along the entire jaw, ensuring that the workpiece is always held securely, even under firm pressure. The two jaws are perfect for forming different curves and bends in sheet and wire. Use the flat jaw to form broader, wider curves and angled bends; use the half-round jaw to shape more precise bends. Choose parallel-action pliers when you need to hold a workpiece or other object securely while at the same time applying firm pressure to it; the secure grip is beneficial for stone-setting and all forming work. These pliers are also a great choice when manipulating wire—you can feed the wire down through the throat of the pliers and hold it firmly along the length of the jaw. The jaws are springless and stay where you position them until you open or close the handles. The texture on the handles helps ensure a firm grip.
