Hanayama Brain Teaser - Vortex
The three pieces of this challenging cast metal brainteaser puzzle each have a spiral body. When assembled, the pieces form a unified flat object. In order to undo this complex entanglement, it will be necessary to unbind them three-dimensionally. Here's a small hint for Akio Yamamoto's Vortex: think "crest."
