Spyderco C101PYL2 Manix 2. A recipe for folding knife success: Start with hard-use rated lock. Add a blade made of Premium Magnacut steel. Manufacture it in Golden, Colorado using precise tolerances then add a healthy dash of American innovation. These ingredients are the Manix 2; a concoction of solo features and when combined, make one of the strongest knives from Spyderco to date. Patented by Spyderco, the Manix 2 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 Premium Magnacut steel 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 Yellow FRN handle scales scalloping areas of the handle's perimeter. This one is not slipping out of your hand and works well with gloves on. 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. Blade length: ~ 3 1/3" Closed length: ~4 5/8"  USA
