Deba knife, blade length 16.5cm, 239g. The back of the blade is about 8.8mm thick near the top of the heel. It's an older model from Seki Magoroku. This is a genuine kasumi blade, made by layering soft iron and steel. The rust marks are mostly gone, but there are still faint marks and small scratches if you look closely, so please check the photos carefully. The handle has been replaced with a new one and should last for a while. It has been thoroughly sharpened, the blade has been honed, and it has been polished. Please see my profile for detailed restoration processes.
