Metal Etching/Engraving onto rustic, non-coated metal

Anyone know of a way to engrave names into some rustic nails? A fiber laser would be nice, cnc could work as well, definitely needing advice for this project.

Thanks,

It may or may not work for you, but it’s possible to do it with either chemical / acid etching or even media blasting if you were to mask off the piece. Neither would be anywhere near as clean and easy as a fiber laser or CNC, though.
