ABSTRACT:
Archery bow pliers for removing a split nock ring from a bow string. The archery bow pliers have a wedge and anvil which are formed to open a split nock ring along its longitudinal cleft, allowing the split nock ring to be removed from a bow string without damaging the bow string or unnecessarily deforming the split nock ring. The archery bow pliers have an anvil member and a wedge member which are pivotably attached to one another. The anvil member has an anvil surface formed adjacent one end. A wedge defined by two converging surfaces is formed on one end of the wedge member corresponding to the anvil surface on the anvil member. Each converging surface engages one free end of the split nock ring on either side of the cleft to wedge the free ends apart sufficiently to allow the bow string to pass therethrough. The split nock ring can then be removed from the bow string and either replaced or relocated on the bow string. The anvil member is also provided with a channel for positioning and guiding the archery bow pliers relative to the bow string in a manner that spaces the bow string from the wedge so as to prevent the wedge from damaging the bow string during removal of the split nock ring.
