What woodworking tool do I need to smooth out narrow grooves?

I removed paint from a few doorframes, and now I'm going to sand them down and repaint. What is the best way to smooth out the grooves in the detail? I held up a pencil in this photo to show the size of the grooves (approx 1.7 mm): link

I'm sort of a basic woodworker. I've been reading about different kinds of rasps, files, and rifflers (a word that is new to me today), but nothing is exactly what I'm looking for I think. I guess I am imagining something like a metal file in the shape of a cotton swab/cotton bud.

I already bought some contour sanding pads for the job, but I'm just wondering if there is a better way of working with this - there are seven doorframes, each with multiple grooves.

BONUS QUESTION: if anyone is able to identify what the metal circle in the photo that was hidden under the paint, that would be cool too.
