Richard, it surprises me that you write the blade is ’silver coloured’, as I would think it would be a ‘
dull/dead silver’ colour.
I have a katar, which ones had am acid bath, I almost cried when I saw it, but I bought it an worked on it for hours – fortunately it was only the blade which had a ‘bath’. What you have to do, is to work on the blade until the acid look disappears – it is not easy, and it will take some time – quite some time, if I am not much wrong – but when you have finished, you are free to try to etch the blade, to see what you find
.
Happy working and a happy New Year to you and yours.
