I have got 7 of Shigefusa Yanagiba Kitaeji 270mm to 360mm blade. It looks originally from old stock of Nihonbashi Kiya which has been deal with Shigefusa for a long time. Nowadays, Shigefusa knife is engraved on "Registered Shigefusa made" on the front side, but those knives are engraved "Shigefusa Saku" on the backside of the blade. It might be 20 years old or more, and I guess that it might be the early days of Shigefusa made knives. Please click here to see extra pictures! Please click here to see extra pictures!
