I just found an old damascus drop point from Atlanta Cutlery. The pattern has been sanded almost completely off to remove rust. I want to knock the old handles off and bring out the pattern and redo the handle. I have access to some FeCl from Radio Shack, but I also thought about bluing it. Can the FeCl be used to etch the pattern out? Would bluing be able to bring out the contrast and pattern? What grit finish is best before etching? I have some file/sanding work to do to flatten the tang and remove all the old epoxy and wood, so I need to know what finish to take it to before etching. I dont have a lot of faith in its cutting ability, but its an old blade from a long time ago, so I want to give it a shot.
