Kiya's Izutsuki, Deba knife, buffalo horn bolster, approximately 15 cm. It can handle slightly larger fish, is easy to maneuver, and I think it's a convenient size for home use. I like Kiya's Izutsuki because of its good shape, ease of sharpening, and sturdy construction. The blade has been lightly sharpened, so I think you can use it right away. How about it? This is an old item, so no claims and no returns, please.
