1) You want to have two flat-nosed (or chain-nosed or bent-nosed or any combination) pliers, one in each hand.
2) Grasp either side of the ring with the pliers so the split part is in the center.
3) Simultaneously move one hand away from you while you move the other hand toward you.
4) Voila! Your ring is open.
Closing Jump Rings
Following the same instructions for opening the rings, youll also have pliers in both hands as you move one hand toward and the other hand away from you. However, youll be closing versus opening the ring and you will actually hear the ring make a small snap sound as the two sides meet together.
When you hear the snap, youve closed the ring.
