Overall, for things like just writing a name on a steel water bottle, this isn’t the most straightforward solution. Etching is traditionally the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio (incised) in the metal. acid etching steel. Acid etching makes use of a chemical reaction between an acidic etchant solution and the steel of your blade. It is a straightforward process, which is used to enhance the appearance of the blade and bring the inherent pattern, lying in wait within the steel, to life. Stephen Stumbo.
