An electrosurgical electrode comprises an elongated body having a cross-sectional area and longitudinal side edges forming longitudinal cutting edges adapted for electrosurgical dissection along a plane. The body has a configuration, wherein: the thickness of the side edge is greater than 0.01″, forming two or more cutting edges, and the cross-sectional area-to-number of cutting edges ratio is less than or equal to 0.0004 in2 per cutting edge； the thickness of the side edge is less than or equal to 0.01″, forming only one cutting edge, and the cross-sectional area-to-number of cutting edges ratio is less than or equal to 0.000150 in2 per cutting edge； or the thickness of a first side edge is greater than 0.01″ and the thickness of a second side edge is less than or equal to 0.01″, and the cross-sectional area-to-number of cutting edges ratio is less than or equal to 0.001 per cutting edge.
