This tool is simply the easiest way to make a loop in lampworking. Instead of pulling a loop with stringer you simply heat a bump and pierce with the Loop Nippers. Wiggle the jaws a little to widen the hole and polish briefly in the flame. Job's a good 'un. Easy, easy, easy.
These steel nipper pliers are full size - 5 inch (12.5cm) and have lap jointed jaws.
