Thanks for the observations and advice guys!
I'll get to work to clean this blade of its rust. I know it doesn't have koftgari and probably not a wootz blade, and wasn't owned by Shivaji or Guru Amar Das... but I like it. It's simplicity is elegant and it's elegance is simple... but rusty.
Just curious, what type of rust remover would you guys suggest?
I have WD40, but I don't know if that would be appropriate.
Again, thanks.
