The Knockout features Kershaw's Sub-Frame Lock. 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. Then there's the blade itself. It's a modified drop point in high-performance Sandvik 14C28N stainless steel with a stonewashed finish. It offers excellent corrosion resistance and hardenability. The finish provides extra protection against rust, too. 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 thumbstud and the blade moves out of the handle quickly and easily. The Knockout also comes with our deep-carry pocketclip 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.
