very nice work!! you always have to try new things, that is the way to learn. Engraving?? veeeery difficult to master, but certainly some basic things can be done.

I was also thinking in giving a try at some very basic engraving and have found a local shop with tools for engraver in jewelry, so I will but 2-3 hardened pencils (I dont know the correct name in English).

If I could make some basic flowers in screws for example, I would be mooooore than happy
