Things to consider:
Low end hobby store pliers are just that-low end and not meant to last so the price per use could end up being pretty high. Instead of my better, more expensive tools, I use the hobby store pink handle pair, left in the photo, to hold wire when making balled head pins using a torch. The inside surface of the jaws is not smooth like higher end pliers, so they hold wire securely. The surface inside lower end flat nose pliers jaws (not shown) makes it easier to secure soldered jump rings when making them into ovals. The black surface on the tips of the round nose pliers, second from the left, is not smooth, making it easier to hold a wire end to start a spiral coil. Smooth surfaces on higher end tools, the two on the right, are less likely to mar metal.
