An electrosurgical apparatus for sealing and cutting tissue includes forceps and a power supply. The forceps include jaws that are pivotal about a pin and at least one blade disposed between the jaws. A shaft connects a handle to the jaws for moving the jaws while also conducting electric current from the power supply through the jaws. A wire, routed through the shaft and through a hole in the pin, connects a knob to the blade for moving the blade. In a bipolar configuration, the wire also conducts the electric current through the blade.
