An end effector of a forceps includes first and second jaw members movable between spaced-apart and approximated positions for grasping tissue. Each jaw member includes a tissue sealing plate that is selectively energizable. The tissue sealing plates are configured to conduct energy therebetween and though tissue to seal tissue. A knife includes a distal surface and an upper surface. The knife is selectively translatable between a retracted position and an extended position wherein the knife extends between the jaw members. The distal surface is configured for dynamic tissue cutting upon translation of the knife from the retracted to the extended position. The upper surface is configured for static tissue cutting with the knife in the extended position. The knife is selectively energizable and is configured to conduct energy between the knife and one or both of the tissue sealing plates and through tissue to electrically cut tissue.
