Ax from a construction pickaxe. Drawing on metal

The video shows an ax forged from a construction pickaxe.
Ax forging video: https://www.youtube.com/watch?v=Dfa9YPP51pI&t=1s
After hardening in machine oil, the ax is covered with a layer of scale. In order to remove the scale, I dip the ax in 9% vinegar. The ax is in vinegar for 3 days.
To protect the metal during etching, I use an alkyd spray paint.
I print the drawing on the paint. I use a film and a pencil with a thin shaft.
I scratch the paint with a metal needle.
For metal etching, I use an aqueous solution of ferric chloride. 1L. water for 1kg. ferric chloride. The first time the etching took place for 60 minutes, and the second time - 30 minutes, at an air temperature of 18C.
To remove paint or varnish, I use a solvent such as acetone.
For blackening metal, I use Klever Ballistol Schnellbrunierung 50 ml.
Finally, I spray the entire ax with lube to prevent oxidation.

Thank you for attention.
