I haven't ruled it out. I'm going to try a few more coats of cold blue and see if the color will even out. It won't affect the knifw's performance, just the appearance. If that doesn't work, I'll redo it. I have until Christmas and I have six of them finished. If I do that, I'll probably sand off the bluing and try to polish it and see if I can get a half way decent more traditional hamon.
