The present invention is directed towards an electrosurgical cutting system. The system comprises an electrically conductive blade, having an uninsulated cutting edge that is surrounded by an insulator. A source of pulsed electrical energy may be coupled to the electrically conductive blade to provide a substantially uniform and highly enhanced electric field along a cutting portion of the blade edge. The blade may have a uniform rate of erosion during use, so that both the conductive metal edge and the surrounding insulation layer erode at approximately the same rate. Also described are methods of fabricating insulated cutting electrodes, particularly blade electrodes.

A surgical saw blade operatively couples to an oscillatory power tool for oscillation about an oscillation axis (OA). The saw blade includes a plurality of cutting teeth separated from one another by a clean out opening along a distal end. The clean out opening comprises an arcuate closed end and straight side walls extending from the closed end.
