I'm not sure that it will stain nickelous pamor in the same way as it will ferric material. I have never tried a full blade, only ever used it to touch up worn areas. I think that the effect on nickel would probably be that it would give it a brownish tinge, but I think this could probably be polished off with steel wool on a toothpick. With care you could fake a proper stain I believe.

However, the problem is this:- not all pamor is simple modern nickel. If its pamor Luwu it will most likely contain iron, and that will stain dark and be uncleanable. If it is high phosphorus iron it will stain just the same as the rest of the blade, but with a different colour.

Best to limit the use of cold blue to a touch up job.
