Thank you for viewing. This is a Kiritsuke Gyuto knife, a Hon-yaki (fully hardened) blade, 240mm in length. The handle is a high-grade black water buffalo horn ferrule with an octagonal ebony wood handle. It has a beautiful Hamon (blade pattern). I believe the steel is Shirogami (white paper steel). A saya (sheath) is not included.
