*prepares necro-post of the decade…
A yoyo with studs or spikes on the rim. Many uninformed individuals believe that yoyos were weapons, reinforced by the fact that you can hit yourself and others pretty hard with them. I feel like if someone modded a yoyo to have studs on the rims (making a weaponized throw, idk) it would be a pain to catch, let alone hitting something with it.
Someone made one that had spike that came out with enough spin so that you could pop balloons with it lol. Worked on a similar principle to the Brain mechanism.
I wish I could remember where I heard this, it was either Brown and McBrides “YoYo Player” or Hollywood Moderns “Kill Your YoYo”
You’d get good at regens in a hurry.
Small diameter, super wide, lightweight, plastic with ss finger spin hub. Shape is like high walled but not organic like more uncomfortable and doesn’t push the weight to the rims.
A yoyo that talks to you and makes recommendations as you throw… Being sure to criticize and talk you through each trick. A backseat driver yoyo would get pretty annoying.
An Alexa enabled yoyo!
Most cursed yoyo I’ve actually played - the “Sky Bounce” yoyo that was beyond oversized, had inflated rims. Found one loose at walmart and gave it a spin before it tried to attack me.
I love that the inspiration for this CAD was a cybertruck! 
Looks like a SPYY Ronin or Noctu. Pretty cool looking throws imo, if sharp.
This but square
Forgot about that one (thankfully). This takes the cake. Gentry was not amused 
sandpaper response pads.
I think you just invented a more fun way of sanding small objects.
This should be super easy to 3d print @AudreySickburn thoughts?
Ok this is way more fantasy than anything…but how about a yoyo-themed Screamin’ Swing ride? Made this cursed animated prop in the Planet Coaster game, yoyo indefinitely does a Dizzy Baby. It may or may not have collision issues with the ride arms 
I looked all over YouTube, I could not find much needed context to this lmao.
Story time?
