An end effector assembly for use with an electrosurgical instrument, the end effector assembly comprising: first and second jaw members each defining an opposed inwardly-facing surface and an outwardly-facing surface, at least one of the first or second jaw members movable relative to the other between an open position and a closed position for grasping tissue between the inwardly-facing surfaces thereof, the end effector assembly characterized by: a dynamic electrosurgical cutting portion disposed on the outwardly-facing surface of one of the first or second jaw members, the dynamic electrosurgical cutting portion including first and second electrically-conductive cutting elements and a first insulating element positioned between the first and second electrically-conductive cutting elements, the first and second electrically-conductive cutting elements adapted to connect to a source of electrosurgical energy at different potentials to enable the conduction of energy from one of the first or second electrically-conductive cutting elements, through tissue adjacent the dynamic electrosurgical cutting portion, to the other of the first or second electrically-conductive cutting elements to dynamically electrically transect tissue upon movement of the dynamic electrosurgical cutting portion relative to tissue with the dynamic electrosurgical cutting portion activated, wherein the first insulating element is configured to facilitate dynamic electrical transection of tissue.
