An ultrasonic tip for fibrous tissue removal. The ultrasonic tip may be configured for at least torsional vibration and coupled to a distal end of a shaft of a surgical instrument with the shaft including a vibration conversion mechanism. The ultrasonic tip includes a plurality of slots extending between inner and outer circumferential surfaces to form a plurality of teeth. A depth of one of the slots at the outer circumferential surface is greater than a depth of the slot at the inner circumferential surface to define a sloped surface. The teeth include a cutting edge defined between the outer circumferential surface and a side surface defining the slot. The cutting edge includes a positive rake angle. The teeth may further include an inner cutting edge defined between the sloped surface and the inner circumferential surface with the inner cutting edge having a positive rake angle.
