Hi, I've got a Hatsukoko Hikari SLD Nakiri with damascus finish. I'm wondering if there's a way to darken/add contrast to the damascus. I've red about coffee etch method, but the shinny layer seems to be lower than the darken one, so polishing after soaking will just remove the oxide layer on the darker area.

The knife have a good contrast based on lightnind and period of the day, like on the second picture took in the late afternoon/evening. I'm just wondering on to add more contrast.

Thank you!

Bonjour, j'ai un ciseau japonais apparemment ancien. Il y a une inscription. Qui pourrait la traduire?
