ABSTRACT:
An ultrasonic blade includes a blade body and a cutting edge. The blade body is defined about a generally axial line. The cutting edge is on the blade body and is defined by the intersection of a first surface and a second surface. The first surface includes a first incident angle of about 0° to 35° from the axial line and a first curve of about 10° to 20° formed at the first incident angle. The second surface includes a second incident angle of about 0° to −35° from the axial line and a second curve of about 10° to 20° formed at the second incident angle.
