In one embodiment, a surgical instrument comprises an articulable waveguide. The articulable waveguide may be configured to transmit ultrasonic energy therealong. The articulable waveguide comprises a proximal drive section, an end effector and a first flexible. The proximal drive section is configured to couple to an ultrasonic transducer. The end effector is located at a distal portion of the articulable waveguide. The first flexible section comprises a flex bias and be positioned between the proximal drive section and the end effector. The surgical instrument further comprises a first tine extending longitudinally relative to the articulable waveguide.
