An electrosurgical instrument for cutting tissue includes a blade assembly. The blade assembly includes a first electrode having a first pre-selected shape and a first distal edge, and a second electrode disposed in spaced relation relative to the first electrode. The second electrode includes a second pre-selected shape and a second distal edge, where the first distal edge and the second distal edge form an electrically conductive tissue cutting surface extending along the distal end of the instrument. The tissue cutting surface is adapted to connect to a source of electrosurgical energy such that the tissue cutting surface is capable of conducting electrosurgical energy through tissue adjacent thereto to effectively cut tissue.
