What is this?

Question

Oooh. My boyfriend found it (it was his dads) and neither of us knew what it was.

Answer

Looks like a tool that's used to mark leather for stitches. Or something used in BDSM play.

Answer

It’s a Wartenberg wheel, also called a Wartenberg pinwheel or Wartenberg neurowheel, is a medical device for neurological use. The wheel was designed to test nerve reactions (sensitivity) as it rolled systematically across the skin.
HOWEVER LOL it’s used in BDSM sex play too

Answer

My neurologist has one, but I’ve also seen it used in S&M, I’ve also seen people use it in the kitchen when making dough and making shapes edges, so not really sure what you’re looking for, I’m going to guess you’re probably concerned because you found it your husband or boyfriend, and now you’re wondering what he’s up to. I would be asking him.
