Patented by Spyderco, the Manix2 has a Ball Bearing Lock. It's a hardened free-floating ball bearing contained in a custom hi-tech polymer cage. The round ball bearing allows the lock to self adjust across a large surface, smoothly and consistently locking-up with solid confidence. Evolving over time, the Ball Bearing Lock's strength withstands hard work with a secure, versatile and comfortable grip. Ergonomics are peerless in this design. The blade is Crucible CPM S30V and flat-ground with aggressive thumb serrations (jimping) above a super sized 14mm Spyderco Round Hole. The Jimping doesn't stop there. With full steel liners the scales have jimping that extends beyond the G-10 handle scales scalloping areas of the handle's perimeter. The liners pull double purpose by adding rigidly and lightweight strength to the handle. A three-screw clip is left/right-hand carry, positioned for comfort and deep pocket carry. The knife also has a large lanyard pipe to protect various types of cords or thongs.
