I think that different steel react better with one or the other. And it depend on the wished result.
I personally etch as well with vinegar similar as described in up but heat the etchant and blade, the reaction is faster and deeper.
Of course you get better results when the blade is fine polished and free from rust so far possible.

Hi Delef,
Many thanks to you also, and I do understand what you say as regards the temperature of the object and etchant; I'll opt for vinegar and see what appears if anything??
