How do I securely open and close an open jump ring?
Unsoldered (open) jump rings can be opened and closed laterally with chain nose or flat nose pliers. One common method is to hold the jump ring between two chain nose pliers with the opening at 12 oclock while holding the tips of the pliers at 10 oclock and 2 oclock. Use the pliers to move the ends away from each other with a twist of your wrists — one towards you and one away from you. Close the jump ring by doing the same steps in reverse, wiggling the ends together to close. This method allows the jump ring to hold its shape and strength.
