Deba knives are Japanese knives used for filleting fish, and are suitable for tasks such as removing the head and performing the three-piece filleting technique. This item feels like it has hardly been used. This item is a single-edged, steel knife, and its appeal lies in its solid thickness and sharp cutting ability. It has also been sharpened, so you can use it immediately upon arrival. Please be careful when unpacking. Of course, the sharpening fee is included in the price. The knife is very well sharpened and kept clean. It's definitely a great deal. I recommend it with confidence.
