The innovative Seki Magoroku All-Purpose Knife Composite features a double-edged blade. The blade of the Composite all-purpose knife combines two different types of steel, creating an exciting contrast on the blade. The two types of steel in the Composite all-purpose knife are joined together with a special copper soldering, leaving a delicate copper line visible between the types as a special detail. The slender handle of the Composite all-purpose knife is made of light Pakkawood, and its shape and the cross-grain pattern convey a particularly light dynamism.
