Such a good idea! I hate carrying yo-yos around because they’re usually too awkward for pockets. I need a collapsable yo-yo in my life.

Amazing! Are there grooves cut in the pieces so they stay assembled or is it pressure like a Morse taper?

It’s conic holes on conic shims
With a plastic yoyo it would be much more easier.
But here, we don’t like easy stuff

So To do it, I would need to buy 3 b-rush, the machinery, and be skilled enough to not mess up?
