Chiyozuru
Chiyozuru is one of the most well-known names for plane blades and other woodworking tools in Japan. Many of these forged tools from current and previous generations are viewed as national cultural treasures in Japan. Furthermore, the tools have also received numerous awards. After a thirteen-year apprenticeship under his master, Chiyozuru Sadahide II (fourth generation) was granted permission to manufacture and sell his own tools bearing the Chiyozuru name.
