A surgical instrument, comprising: an ultrasonic transducer; an ultrasonic transmission waveguide extending from the ultrasonic transducer; and an ultrasonic blade acoustically coupled to the ultrasonic transmission waveguide, wherein the ultrasonic blade comprises: a base; and a curved body extending distally from the base, wherein the curved body comprises: a tissue-treating surface extending on a first side of the curved body; and a curved cutting edge extending on a second side of the curved body opposite the first side, wherein the curved cutting edge comprises: a proximal end; and a distal end, wherein the proximal end is offset from the distal end in a first direction that results from the blade being tapered such that the proximal end of the cutting edge is further away from a plane defined by the tissue-treating surface than the distal end of the cutting edge, wherein the proximal end is offset from the distal end in a second direction, and wherein the first direction is perpendicular to the second direction such that the proximal end and the distal end reside on opposites sides of an XZ plane, wherein the XZ plane transects the tissue-treating surface at an angle of 90° and extends along a centerline that extends through the base. an ultrasonic transducer;
