Koutetsu

Koutetsu is sharpener Takayuki Shibata's personal brand, his notes for it: "Japan's first ironclad ship. Her name means, literally, "Ironclad." (甲鉄) The Koutetsu had a very unusual bow. It looks like my knife. And the Koutetsu was the first in her class, and she used a pioneering, "cutting-edge" design - just like my knife."
