Round Nose Pliers
Round-nose pliers have jaws that look like tapered cones and are used exclusively to create loops and rounded shapes. They should not be used for grasping wire, as pressure can weaken the metal by forming an indent that changes its shape.
Round-nose pliers come in handy for making various loops. The jaws of the round nose are wide at the base and tapered towards a narrower tip, allowing you to vary your loop size depending on where along the jawline you place your wire.
