Deba knife, blade length 18.1cm, 343g. The spine is about 9.8mm thick near the top of the heel. It's a brand from Masamune Hamono (Masamune Co., Ltd.) in Kokurakita-ku, Kitakyushu City, Fukuoka. It seems to be located in the Tanga Market, known as the kitchen of Kitakyushu, which often makes the news due to fires. It's a genuine kasumi knife, made by layering soft iron and steel. I don't think it's the manufacturer, so I suspect it originated from Sakai or somewhere similar. It's generally clean, but there's some light rust on both sides, so please check the photos carefully. It shows relatively little use, and the shinogi line is clean. The handle has been replaced with a new one and should last 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.
