2. In terms of maintenance, is mineral oil all that's required? How about the hilt?

3. The asang-asang has some greenish stain that I think is consistent with brass. How do I get it off? Or should I get it off?

Hello Joren,

welcome and I hope, I can give some tips.

1: You should remove the rust spot, because the rust below the black surface is normally still active. Some decades later the rust spot can cause a hole in the blade. You can see this, if you use the flash if you make pictures, the black spot will become red. My technique is a little rough, i use a tiny srewdriver to remove the rust, plus japanese rust eraser (https://www.google.de/search?q=rust+...=1745&bih=1005). Finish with steel wool.
The best way is imho electrolytical rust removing (http://www.instructables.com/id/Elec...val-aka-Magic/).


2: I know, some collectors hate me for my words, but I always use modern synthetic oil like weapon oil, Slide and Bed Ways Oil or Ballistol. Ballistol is also a good rust remover. Renaissance Wax is a good alternative if you do not like the smell of synthetic oil.

3: I suggest, to leave the asang-asang as it is.

Regards,
Roland
