I have tried out a lot of etchants and in my honest opinion the original Zag (Iron + Sulfur but not Vitriol!) is still the best etchant. Difficult to work with, but fantastic results, if one do it right

The Dha/Dao from Sajen was recently etched with Zag for example.
But everybody has different experiences and preferences.
