Yanagiba knife, blade length 19.9cm, 110g. The spine is about 4.0mm thick near the top of the heel. It's a Sakai Toji brand, but it's a product of Izumi Rikiseisakusho Co., Ltd. It's a genuine kasumi blade, made by layering soft iron and steel. It has seen very little use, and both the blade and handle are very clean. The original price wasn't as high as a Sakai Toji Iwakuni-saku, but it was still fairly expensive. The plastic handle retains over 90% of its original luster. It seems like it will last for a long time. It has been thoroughly sharpened, and the blade has been polished. Please see my profile for detailed restoration processes.
