Almost like negative to positive in photography.
My cousin to your blade was done with arsenic & lime.

I don't know if you can get any where you live, but iirc it must be white arsenic.

Interesting. I cant get arsenic here so that is not an option. But it would look better if the effect was reversed. Is there any alternetive method that would produce a result similar to arsenic and lime?
