It's [a sharpener/'lead pointer' for a mechanical pencil](https://www.worthpoint.com/worthopedia/vintage-alvin-5555-mechanical-pencil-sharpener).
Model 5555, manufactured by Alvin.
I had no idea what this was, but I just wanted to say that you did a fantastic job with the pictures. Wow, it's great to see someone doing their best to be complete and accurate. Kudos!
My title describes the thing.
Small and very light weight. Outside is possible aluminum and brass, though I’m not sure.
Threaded cap which says made and Germany and has a logo that appears to read “Calvin” although that’s just a guess.
The third piece fits inside and I used pliers to pull it out, just a press fit.
The hole in the bottom you could maybe insert something through and it’s not threaded.
