A pair of Bali (?) keris, 2 of 2

[S.Workman]

Here is the second of my kris. This one has quite a lot of damage from rust, since it apparently sat in its sheath for a long time without care. I have gotten off pretty much all of the surface rust, but the pitting is quite troubling. There are two odd things with it, one is that the pitting is not black under sun light, it is silver. The other thing is that I was advised to use plumbers flux to remove the last of the corrosion, but that substance made a very dark, bruise like stain on the metal, and it was not easy to get that coloration off. This keris has a pamor noticeable even when cleaned. As with the first one, I am looking forward to reading any comments or suggestions the more knowledgeable might have.
