An ultrasonic surgical blade with improved cutting and coagulation features is disclosed. The blade includes a solid body, a longitudinal portion having a proximal end configured to couple to an ultrasonic transmission waveguide and a transverse portion extending crosswise from the distal end of the longitudinal portion. At least one dissection edge and at least one hemostasis surface is provided on the blade. The transverse portion defines a hook having a free end configured to pull and dissect tissue. Also disclosed is an ultrasonic surgical blade that also includes a sharp central ridge and an end mass for acoustic balance.
