fine
鞙 centers on the idea of fineness, likely referring to something delicate or of high quality. The single given meaning is narrow, and the kanji is rare, so its full conceptual range is unclear.
鞙 combines 革 (leather) with 肙, which likely contributes the sound. The exact historical development is uncertain, and the modern form may be simplified.
Leather 革 that is fine and delicate, like a small worm 肙 (the right side resembles a worm shape), suggests something finely crafted.
For ケン, imagine a fine leather item made by a skilled craftsman named Ken: Ken -> ケン, and his work is always fine.
