If you used thin wire, it could work. Better than this. Anything would be better that this.

As for the engraving route, if what we're talking about is a simple design, I could--tch, no I couldn't. [He grimaces in realization.] The tools I'd need are at home, and I don't think this place is at a high enough tech level for me to remake them. Chusheng!

But yeah, thin wire, preferably hammered to be flatter. Or... magicked to be flatter. Whatever.
