I can think of many reasons that I would not venture into hot salts blueing at home, but you might give Belgium blue, or a traditional slow rust blue a try. In my opinion these are both better looking and more durable finishes in the end anyway (with the edge in durability going to the slow rust blue). In the end it is your metal preparation that is going to mark the difference between a high quality blue and a low grade one. I polish everything by hand and forget about buffing wheels.
I thoroughly disapprove of duels. I consider them unwise and I know they are dangerous. Also, sinful. If a man should challenge me, I would take him kindly and forgivingly by the hand and lead him to a quiet retired spot and kill him.
