A yoyo shape is one of the ways to tell yoyos apart, and what gives them their distinctive looks.
No two yoyos have the same Diameter and Width, with the same shape.
They all are different. Some are similar, but each is special in its own way.
If someone made a yoyo the same shape diameter and width, yoyos wouldn’t be unique.
What’s your favorite shape, what’s the most unique one you have seen?
