4 in 1 multi use pliers.
If you just want one plier then this has to be the one for you. It can create loops, cut, flatten and close jump rings.
It has a partly rounded nose, partly flat nose with cutters in the inner jaw. It even has a notch to help you with your jump rings. Some people love them (one of our members of staff swears by them) but others find them tricky. It’s really just a question of choice, but we sell a lot and customers like them!
