Thanks everybody for the replies and opinions!
Tim: I have no clue what the yellow colour is and how was it made, sorry...
Detlef: I know it is quite a pain to remove the chrome, and in case of this sword it seems to be unnecessary.
Dennee: thank you for the expert opinion; I came to the same conclusion logically. It means that I can leave the blade as it is, and save me some heavy work

It would be interesting to to see other modern swords examples. I am glad to hear that the traditional skills are still alive in Bhutan!
