Bone handles
Initial thought was gravers, but the handles would never hold up to that
Now I'm thinking antique dental tools (just a guess cause they look terrifying)

Nut picks?  Something domestic instead of shop oriented.

Maybe sculpting,,,as in clay?

Carvers or engravers wouldn't have so many ends alike.  I just remember that my parents had a nut set made of a hollow log with a bunch of picks stored in drilled holes around the perimeter. The fact that 7 of yours appear alike (from set of 8?) and 2 are different also seems to support this.  Again,, the handles look too wimpy for shop work.
 
I went to Google with a search to confirm my thought.  I don't have a google account, so I can't attach the link.  Following google lens search to etsy- they show up as a German nut pick set with bone or ivory handles.

Yup, that's exactly what they are and I'm very happy that I got outbid on them in the online auction !!
