How To Etch/Engrave Steel (Guitar Pick Example)

A video of how to customize a guitar pick, this is achieved by running electricity through a salt water solution and the metal to dissolve the exposed parts.
The first section of the video describes the etching/engraving process and the second section describes how to create a template using a laser engraver (a laser engraver is not necessary for the process but simply allows for more precise and exotic patterns).

Indeed I am.
Let me know if you'd like to see anything else (I am attempting to get better at video editing and looking for ideas of things to make).
