I would try something like what you've described . I just was fooling around with trying to get a banana shaped "pattern " patina . I used some mustard and vinegar and laid a banana peel on top and let it bake in the sun (see my 1st post in this thread) . Actually did very little . The O-1 is more corrosion resistant then my cheap old carbon steel kitchen knives for sure . I'm now just letting exposure to tree and brush juices etc from use finish the job . Or maybe I'll try your method ? That's the great thing about a patina : you can erase and start over . Helps me not worry and more enjoy the experience of using the blade .What did you use to patina your O-1 Trail Master? The best one I've seen so far was done with vinegar purchased from WalMart. It was so dark and evenly applied. I wish I could remember where I saw it. The person said that they had rubbed the blade with alcohol and a scotch brite pad beforehand then soaked tge blade for two or three hours and it was done.
