Chopsticks for artisan Hashikura Matsukan.
Chopsticks ordinarily come in pairs, but these ones are a single unit. They are separated into two for eating, then rejoined into one form when not in use. We used CAD and a multi-axis CNC miller to create this unusual shape.

Designed with Nendo design team.
I modeled the splitting surface using "surface sweep with a 270° twist".
