So I've been thinking and considering trying it out.
So, I noticed that my old blades with considerable patina seem to hold up better vs water. Less water marks, no scratches. I then thought about guns, as I'm purchasing one.... Their steel is a little bit diffrent than that of our blades, but most guns are blued, makes them less reflective, more resilient to scratches as well. Its a process which partly protects the steel by oxidizing the iron present, but it does not take up any more volume than the iron itself... unlike rust which takes up more volume than the original. I really dont want to explain all this wrong do the wiki is below.

Have any of you guys tried this? I'm right now searching for some junk blades to see how it looks....
Also, if this is possible, this means you could also change the whole color of a blade, make it brown, green, doing this with chemicals means you could also control where the patina is, you could just dip the spine, or the tang, and keep the blade face mirrored.... hone past the patina for a fresh edge....
also, i was reading about use sulfuric acid to remove some oxidation.... I'm not sure how i feel about that... anyone tried it?
