Chris Reeve Large Sebenza 21 Cocobolo Inlay Knife Stonewash Plain Edge. Typical of Chris Reeve Knives, the pivot strength is more robust than other folders. This Large Sebenza 21 model features a polished S35VN stainless steel blade and a satin finished titanium handle with Cocobolo inlays. Polished gold thumb lug and spacer are chosen to coordinate with the color of the inlay. The frame lock and pocket clip (tip-up) are bead blast finished titanium with lanyard. The large pivot screw and pin are supported by large thrust washers. These perforated phosphor bronze washers reduce friction and double to retain the fluorinated grease for longer lubrication thereby extending the life of the knife.
