These high-quality, German-made prong-opening pliers give you complete control when removing a stone from a setting. The groove in the lower jaw supports the prong, holding it steady, while the claw in the top jaw grips the prong neatly; with the prong held securely, you can easily lever it open without slipping. There is no danger to the stone because all the pressure is put on the prong rather than the stone—no matter how large the prongs.
• These pliers have a sturdy box joint; one half of the joint surrounds the other half and the pivot is contained within. This joint holds its alignment far longer than a lap joint but allows the tool to open only as far as the box size.
• The double-leaf spring consists of flat, tempered metal tabs attached to the inside of each handle, positioned to meet and hold the handles apart (and the jaws open) until they are squeezed closed; the spring delivers fast, strong rebound for improved productivity.
• The plastic-coated handles ensure a secure grip and extended comfort over hours of work.
