1. An ultrapolar electrosurgery blade comprising:
a top thin elongated conductive member and a bottom thin elongated conductive member in vertical alignment with one another and spaced apart from one another along their lengths to form a space between the top and bottom thin elongated conductive members wherein each of the top and bottom thin elongated conductive members includes opposing planar sides, a sharp cutting end and an opposite non-cutting end;
a non-conductive housing that covers both opposing planar sides of the top and bottom thin elongated conductive members and that fills the space between the top and bottom thin elongated conductive members to create opposing non-conductive sides of the ultrapolar electrosurgery blade wherein at least a portion of the sharp cutting ends of the top and bottom thin elongated conductive members and their opposite non-cutting ends remain exposed; and
both a return contact layer and an active contact layer positioned on each of the opposing non-conductive sides of the ultrapolar electrosurgery blade wherein an end of the return contact layer is located near an exposed sharp cutting end of the top thin elongated conductive member without touching the exposed sharp cutting end of the top thin elongated conductive member.
