1. A knotter hook for a twine knotter for producing a loop knot, the knotter hook comprising:
a single stationary clamping wing;
a pivotable clamping wing, wherein the single stationary clamping wing and the pivotable clamping wing comprise an extension component in a same first spatial direction;
wherein the pivotable clamping wing comprises a projection projecting in a direction toward the single stationary clamping wing;
wherein the pivotable clamping wing is configured to pivot reversibly from a closed state into an open state so that a free end of the pivotable clamping wing in the open state is spaced apart farther from the single stationary clamping wing than in the closed state;
wherein the pivotable clamping wing is laterally displaced relative to the single stationary clamping wing at least in sections thereof so that the pivotable clamping wing is arranged adjacent to the single stationary clamping wing and so that below the pivotable clamping wing a free space is formed, wherein the free space is arranged below the projection and extends in the closed state opposite to the first spatial direction beyond the projection;
wherein the projection projects into the free space in the closed state; and
wherein the knotter hook is configured to release a knot formed at the knotter hook from the projection in a downward direction while the pivotable clamping wing is in the closed state.
