A forceps includes an end effector assembly having first and second jaw members. One (or both) of the first and second jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes a longitudinally-extending blade channel defined therein. An electrical cutting insert is releasably engageable within the blade channel of the jaw member such that the jaw member is transitionable between a mechanical cutting mode, wherein the electrical cutting insert is disengaged from the jaw member to permit reciprocation of a knife blade through the blade channel for mechanically cutting tissue grasped between the jaw members, and an electrical cutting mode, wherein the electrical cutting insert is engaged within the blade channel of the jaw member for electrically cutting tissue grasped between the jaw members.
