How would they know that you're rusty?
No one says that interests have to be particularly unique or notable. You are trying to create a bond with an interviewer by casting a fairly wide net. You might catch their interest or you might not.
For instance, I would list something fairly non-specific like hiking. This does not mean, necessarily, that I regularly hike the Appalachian Trail although it could open up a friendly conversation on the subject if your interviewer is so inclined.
More specifically, I would list something like flying remote control helicopters. This could spark genuine related interest from your interviewer or it could open up more widely divergent topics like the various applications of drones or the potential for invasion of privacy issues.
Just be genuine. If you are no longer interested in your weird rusty instrument, I would probably not list it unless you know the interviewer will be hooked. In that case you will just have to parlay your memories of the interest you once had, a slightly more difficult approach.
