@Mei_lito If you’ve never designed a yoyo before, there are some good basics covered in this thread. It won’t specifically apply to tungsten (which will undoubtedly be a different beast to make a full monometal out of), but it might help. I’m interested to see what you come up with. It’s bound to be unique!
More like FreeHand Sub-zero. Indisputable evidence the yoyo was invented as a weapon.
