INCORPORATES OUR SUB-FRAME LOCK FOR A KNIFE THAT'S LIGHTWEIGHT, YET STRONG Sure, the Knockout offers knockout-good looks. But look beyond its awesome exterior to see what's really special. The Knockout features Kershaw's Sub-Frame Lock. What that means is that we've "knocked out" a piece of the machined aluminum frame and attached a stainless-steel plate 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. 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. TECHNICAL SPECIFICATIONS - Flipper May be used on either manual or assisted opening knives. The "flipper" is a protrusion on the back of the blade that the user can pull back on, or flip, in order to move the blade easily out of the handle. - SpeedSafe® Assists you to open any SpeedSafe® knife quickly and easily with a manual push on the thumbstud or pull back on the flipper; built into many Kershaw best sellers. - Sub-Frame Lock One side of a lightweight handle, or frame, is fitted with a steel plate integral to the frame; it is the part of the frame that moves behind the blade to lock it into position during use. Sub-Frame Lock knives can be larger and lighter knife yet with an extremely secure lock. - 4-Position The user may position the pocketclip for tip-up or tip-down, left- or right-handed carry. - Deep Carry - Made In The USA When you see this on one of our knives, it means the knife was made in our Tualatin, Oregon manufacturing facility by skilled Kershaw knifemakers.
