Abstract
The ultrasonic scalpel blade includes a blade having an included blade edge angle of 25.degree. and greater such that, upon application of ultrasonic power, the otherwise blunt blade has a perceived sharpness corresponding to the sharpness of manually used scalpel blades with the added advantage of improved coagulation and hemostasis. Blades are also provided with varying included angles for ultrasonically incising different tissues.
