A surgical instrument is disclosed including a transducer, an ultrasonic blade, a protective sheath, and a non-vibrating clamp arm assembly. The ultrasonic blade extends along the longitudinal axis coupled to the transducer. The ultrasonic blade comprises a body having a proximal end and a distal end. The distal end is movable along the longitudinal axis by vibrations produced by the transducer. The protective sheath comprises a proximal end and a distal end and disposed adjacent to the body. The protective sheath further comprises a pad positioned toward the distal end of the protective sheath and located between the body and the distal end of the protective sheath. The non-vibrating clamp arm assembly has a proximal end and a distal end and pivotally positioned adjacent to the body. The clamp arm assembly is pivotally moveable from an open position to a closed position.
