The olive drab Knockout is a sturdy modified drop-point Sandvik 14C28N stainless steel with a black DLC (Diamond-Like Carbon) coating. The handle is a light-weight, high-quality olive drab anodized aluminum. The Knockout is equipped with SpeedSafe? assisted opening for smooth and easy one-handed opening. Pull back on the built-in flipper or push on the thumb stud and the blade moves out of the handle quickly and easily. The Knockout features Kershaw’s Sub-Frame Lock meaning a piece of the machined aluminum frame is removed and a stainless-steel plate is attached in its place. It’s this steel plate that moves behind the knife blade to lock it open safely and very securely. Yet because only part of the knife handle or frame is steel, the Knockout can maintain its fighting weight and still provide a strong frame lock. You get a knife that’s big, yet lightweight enough to carry every day. It offers excellent corrosion resistance and hardenability. The finish provides extra protection against rust, too. The Knockout also comes with Kershaw’s deep-carry pocket clip so the knife can sit all the way down in your pocket. Even better, the handle is drilled for 4-position carry. Lightweight and versatile, the Knockout is destined to be your new favorite every day carrying knife.
