Nambu-tekki (cast iron) was first made in the middle of the 17th century in Iwate, northern Japan, an area rich with the raw material. A traditional craft, it remains popular today. This charming bottle opener features an abstract crow motif and stands upright, creating a mini sculpture. The characteristic black color is the result of a lacquer glaze called urushi which prevents rust. Pro tip: the foot and tail combine to perform the bottle cap opening operation, not the beak.
