These great little folders are called Higo No Kami. They are made with Hitachi Blue #2 and clad with soft iron. They have a really attractive rustic look to them and are unique pieces made by the Blacksmith Tomita-san at his tiny shop in Miki Japan. Tojita-san was born in 1945 and is a 3rd generation blacksmith. He's been working as a blacksmith for 45 years. The small one measures 150mm open and 100mm closed.
