I have created a revision to a nail writer, Was wondering on the ethics of this. I would like to open a discussion concerning who I should give credit to or if I even should. My design is original compared to anything I’ve seen but alas it is an under nail writer which has been done. Thanks in advance!

If you know the history of the thing, then you also know who's got their thumb in that pie, gone for sharp(ie), waxed and magnetized their boons for grease pencil and ... so ask the workers or historians to check what's new about your item.

Anyone gotten good at swipe on their phones?

I don’t know the history of it however The book on it just arrived, and I am ecstatic to say the least. I currently only have 4 versions. 1.3mm lead,1.3mm different angle,2mmHB,4MM Grease. Magnetic versions are coming soon. Mine is very small and resin 3d printed. Open to discussion if any Historians happen to be hanging out in this Sub. Thanks for the Reply Jonathan.
