Just walking around and you stumble across a rusted Japanese knife? Really? You sand blast it, and there’s no pitting on a carbon knife? Is this a fake restoration? Sure seems like it. A month to sharpen it? Hahaha

For those who don't know, this is a right-handed knife for fish filleting, called a deba. They are usually made of carbon steel because that can be made sharper, but prone to rust, of course, as seen in this video. Left-handed deba are widely available in Japan, but I am not sure about overseas. If you are left-handed, be sure to get the correct-handed deba ! It is impossible to use a right-handed deb with the left hand, and vice-versa, as it will dig into the fish bones and generally make a big mess.
