A device for manipulating a wire includes a first structure and a second structure pivotably mounted with respect to each other so as to define respective facing surfaces configured for alternating between a closed position and at least one open position, where each of the respective facing surfaces includes one or more detent elements and one or more tooth elements extending therefrom. In the device, the tooth elements of the first structure and the second structure are in an interlocking and overlapping arrangement in at least the closed position. Further, each of the tooth elements has a concave surface for defining a passage between the facing surface in the at least one open position. Additionally, each of the detent elements is arranged to face the concave surface of one of the tooth elements of an opposite one of the respective facing surfaces in the closed position.
