How is this finish achieved? Looks like the edges of the heat blades have been sanded down to bare metal, presumably after the rest has been powder coated black? http://www.nydesmo.com/images/415039837_f3cc93d5bb_o_1_.jpg
Correct as above but you would need to lacquer (heatproof) the bare metal parts or they would corrode if you don't keep polishing them.
