Yanagiba knife, blade length 21.1cm, 107g. The spine is about 3.6mm thick near the top of the heel. Unfortunately, the maker's mark has disappeared. This is an authentic kasumi blade, made by laminating soft iron and steel. While most of the rust stains have been removed, faint marks and small scratches remain, so please check the photos carefully. The handle has been replaced with a new one and should last for a long time. The blade has been thoroughly sharpened and polished. Please see my profile for detailed restoration processes.
