Antique guitar pick......boy..we have come along way!.......smile...

Yep looks like a tuning fork alright...old school way of tuning an instrument!
It's Gustav Van Halen- inventor of the first wammy bar!
You don't hold a tuning fork like chopsticks...
I think is a caliper, hes showing off his tool because hes a builder.
Yup, looks like a caliper to me. Or maybe it's an old school split coil stereo pup, adjustable for various string spacings? Adjustable Appalachian Nosepick?
I agree with Mike Cossey. It's an adjustable pick that will strum BOTH sets of strings in unison.
