Hi John, I don’t know what a burnishing tool looks like or what burnishing is exactly, I just start by lightly rubbing the blue serface until I get a grey and then begin to lightly scratching for detail, have to have soft hands, I actually take knife graver at a severe angle to turn metal white by dragging it, hard to explain but it works for me. I will send pictures of the only tools I use in order of progression.Thanks for your comments.
