I am going to guess that those who are/were interested in Rockstead are/were in it for three things: insanely high HRC, convex grind, and beautiful mirror-finish. Of these three, it's the latter that I wish to mention here. If you are into that sort of thing, then chances are you already have tried or have plans in the near future to mirror-polish a knife. Not an ordinary knife but those made of materials that are high in carbides, particularly vanadium carbide.
Just recently I decided to start my very first project - bringing that flawless mirror-finish to my M390 knife. Not just the edge but the ENTIRE blade. The spine, false-edge, and the primary & secondary bevels. So it is no ordinary undertaking, a task that I would feel better treading with the advice from those who have experience in polishing carbide-rich alloys.
There is already a thread titled, "
Mirror polishing M390?" in the Knifemaker's Discussion subforum. Unfortunately, that entire section hardly sees much traffic. So I am mentioning it here in order to get some experienced knife-polishers who might happen to be frequenting this thread, however remote that might be, to contribute and hopefully pass on some your wisdom so that my very first project doesn't turn into a complete disaster.
Thanks!
