The classy Kershaw Highball features clean lines and a high-performance blade of D2 steel. This high-carbon tool steel is wear resistant, tough, and offers excellent edge retention. The blade has a two-toned finish: machine stain on the grinds and gray PVD on a recessed groove in the blade upper. This fully manual knife can be opened one-handed using the recessed groove in the handle like you would a thumb stud. But because there is no thumb stud, the Highball retains its streamlined look. The steel handle is contoured for a comfortable grip. A pop of blue comes from the custom trim ring that surrounds the pivot.
