this is the other info from a seller.....Kershaw's "Steven Seagal" knife is a big, handsome knife specifically created to fit Mr. Seagal's hand. The blade features his signature in English on one side and in Japanese characters on the other. (Seagal is also well known as a 7th Degree, Black Belt Aikido Master.) The knife has another exceptional feature: the handle includes a genuine stingray leather insert. Because of its beauty and durability, stingray leather has been used for centuries to enhance a wide array of products. It is most well known, however, for its use on Japanese sword handles. This is the tradition Seagal had in mind when specified stingray leather for the handle of the knife that bears his name
