So, @rek had these sort of metal quill tips, I don't know how they're called.
I can't help but be amazed by their simplicity. It's a single piece of folded metal that'll fit over almost anything. Here I stuffed the end of a mixing stick into it, and turning into a pen.
I don't know why I have never seen those before.
@neauoire @rek
It's called a "nib".
