I am very new to the knife collecting world. I currently have a D2 knife that I carry daily but I wanted to know what would be the best way to darken the color of the blade and potentially provide more corrosion resistance as well. I’m considering acid-etching but have also heard you could soak a knife in vinegar as well.
What would be the best option here? Any help is appreciated.
I used ferric chloride on my Elementum (D2), and it turned out really dark. I then tried copper/brass washing it and it looked great for a few days, but rubbed off easily. Still has a bit of fleck/shiny spots, but otherwise just dark grey.
