(For those who purchase now, we will give you a Yokote knife as a service.) This is a Suigetsu hand-forged large Deba knife. We received the following evaluation from a seafood processing company that purchased the Suigetsu: "The sharpness and ease of use are beyond the price. We used it to dismantle large fish, and the sharpness was outstanding, with no chipping." We would like to deliver this to those who use it at home or at work. Length: 380 mm Thickness: 10 mm Blade length: 215 mm Weight: Approximately 500 grams (Please note that there may be variations due to being handmade.) Please purchase after understanding the above. Please refrain from purchasing if you are overly concerned about details.
