The signature model of Kim Dong Young, who showcases a dynamic and powerful 3A style that leverages his physique.
What he sought in his ideal yo-yo was powerful rotational performance to support long combos and a strong presence that could be felt throughout play.
Typical bi-metal yo-yos achieve high rotational power by concentrating weight on the outer rim. However, designs that prioritize rotational power often result in a lighter center, which can make the yo-yo feel less substantial during play.

High rotational power and a strong presence.
DON achieves a high-level balance between these two, which are often contradictory.

In 3A models, an inner rim structure that prioritizes durability is often chosen, considering situations where yo-yos may come into contact with each other. Nevertheless, to achieve the powerful rotational performance he desired, an outer rim structure was deliberately adopted.
Furthermore, by distributing weight appropriately without making the width unnecessarily wide, it maintains powerful rotational performance while achieving a solid feel of operation.
The shape, which fits comfortably in the hand and is easy to grip, naturally supports throws with the non-dominant hand, which can be challenging even for advanced players.

What emerged from the pursuit of Kim Dong Young's ideals is an orthodox bi-metal model that compromises neither rotational power nor presence.
