Wire looping pliers can be used for making simple wire loops, wrapped loops, and eye pins without having to switch back and forth between round nosed and chain nosed pliers throughout the process.
While not an absolute necessity, these special jewelry making pliers can certainly save time when making a large quantity of loops – such as in rosary style linked beaded chains – and are quite fun to use!
Regular wire looping pliers like the ones in the video have a continuous tapered round jaw, but there are also 3-step looping pliers with 3 separate cylindrical areas of different diameters for creating consistent sized loops every time.
