Electrosurgery blades including electrosurgery blade assemblies having argon beam capability. The electrosurgery blade includes a non-conductive planar member having opposite planar sides with a bottom angled sharp cutting edge, and a conductive layer located on one or both of the opposing planar sides of the non-conductive planar member where the conductive layer lies adjacent to the angled sharp cutting edge of the non-conductive planar member without covering the angled sharp cutting edge. In embodiments of the electrosurgery blade assemblies having argon beam capability, the electrosurgery blade assembly includes a non-conductive tube member having a hollow tubular shaped opening and a slot where at least a portion of the conductive layer of the electrosurgery blade is positioned within the slot of the non-conductive tube member.
