Nambu Cast Iron was first made in the middle of the 17th century in Iwate, Northern Japan. A master from Kyoto was summoned there to create an iron pot for a tea ceremony, and it was the beginning of the Nambu Tekki (Cast Iron) craft. It became exemplary of Japanese Traditional Craft, and is still popular today. The black color is the result of a Japanese lacquer glaze call urushi which prevents rust. The Nambe Tekki Tool Bottle Openers are part of a range of animal and symbol designs created in the famed material for this collection offered from Saikai.
