The Kumiki Ship shape Wooden brain teaser puzzle contains 16 non identical pieces that designed to resemble a ship.
In Japanese the word kumiki means "joining wood together" and refers to varieties of wood craft. In the puzzling world it refers to 3D interlocking wood puzzle that resembled a familiar shape like buildings, vehicles and animals, not just abstract shapes like spheres and cubes.
Tsunetaro Yamanaka (1874-1954) from Japan was the first craftsman to develop the figural wooden interlocking puzzles known as kumiki.
The object of this puzzle is to take it apart and then put it back together to form the original ship shape.
