Soft jaw flat nose pliers are a must for bead, wire, and metal artists and are in almost every jewelry maker's toolbox. Pulling bent wire between the closed jaws makes quick work of straightening it. Metal and wire can be bent and manipulated without scratching, marring, or gouging it. The nylon jaw pliers in the first photo are a must in any wireworker's tool arsenal. When the jaws become too mangled to use, the nylon jaws are easily replaceable. The pliers in the second photo are inexpensive hobby store pliers and the jaws are not replaceable-they even often fall off the pliers with use so need to be glued back in place. The plastic on these pliers is hard but gouges easily and is not as forgiving as the nylon replaceable jaws. However, they do have their uses. The wider jaws make them more useful for opening and closing large and/or heavy gauge jump rings. On both the pliers, the nylon/plastic jaws can be lightly filed to a bit smoother surface, if needed.
