An electrosurgical cutting device comprises an instrument body, and first and second cutting blades, at least one of which is pivotally mounted on the body to execute a scissor action with respect to the other blade. Electrical supply conductors associated with the body supply an electrosurgical voltage to the first and second blades. The first blade is a composite blade comprising a conductive outer electrode, an inner conductive layer, sandwiched between the outer electrode and the inner layer, an insulating layer. The supply conductors are connected respectively to the outer electrode and to the inner layer.
