Kershaw Knives

The Kershaw Knockout certainly is just that...a knockout. This US made frame lock features such time tested features as SpeedSafe assisted opening, ambidextrous flipper, and four position pocket clip. It moves beyond the original Knockout by sporting olive drab handles and a black DLC coated blade!
The original Knockout continues to deliver knockout good looks and top performance. But now we've kicked it up a notch with an olive-green handle and black DLC-coated blade.

The new olive-and-black Knockout still has its namesake “knocked out” section in the handle. This knocked-out piece in the anodized aluminum frame is replaced with a stainless-steel plate to form our sub-frame lock. This steel plate moves behind the knife blade to lock it open safely and securely. Yet because only part of the knife handle or frame is steel, the Knockout can maintain a lighter fighting weight and still provide a strong lock. The result is a knife that’s big, yet lightweight enough to carry every day.

The blade is a modified drop point in high-performance Sandvik 14C28N stainless steel with matte black DLC coating. The steel offers excellent corrosion resistance and hardenability, while the coating protects the blade and enhances performance.

The Knockout is equipped with SpeedSafe® assisted opening for smooth and easy one-handed opening. Just pull back on the built-in flipper or push on the thumbstud and the blade moves out of the handle quickly and easily.

The new olive-and-black Knockout also comes with Kershaw’s deep-carry pocketclip so the knife can sit all the way down in the pocket. Even better, the handle is drilled for 4-position carry. Lightweight and versatile, this Knockout provides a new color combination that will make it an ongoing favorite.
  • 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.
  • Quad-carry - The user may position the pocketclip for tip-up or tip-down, left- or right-handed carry.
  • Made In The USA - When you see this on one of the knives, it means this knife was made in eir Tualatin, Oregon manufacturing facility by skilled Kershaw knifemakers.

Pros: Lock Type, Pocket Clip, Handle Feel, Blade Sharpness, Blade Material, Ease of Opening, Weight, Lock Ease of Use, Overall Quality
Cons: None
While I own quite a few Kershaw knives, this is only the second USA built knife I have. The difference is noticeable. Not that there is any thing wrong with the imports, but the USA built knives just seem to have "more" quality. Nice slim design with enough heft to it to make it feel durable. Decent grip from the smooth aluminum handles. Shaving sharp out of the box. About twenty percent lockup. No blade play in any direction. Opens easily with either the thumb studs or flipper. Like the sub-frame lock. Reminds me of the Zero Tolerance 777. Balance is great in the hand, pretty neutral. Not blade or handle heavy. Feels smaller than it is. Kershaw USA seems to be building knives similar in quality to ZT at a lower price point. Maybe the ZT knives will be a bit more durable, but for most of us, we probably won't notice the difference. This is a great knife, no matter the price. I also own five ZT's, and love every one, but I can't find anything that much better from them to this one. ZT's are overbuilt just like the advertising says. But if you don't need that, Kershaw USA can give you everything you need at a lower cost. Like I said, I love my ZT's, but Kershaw USA is right up there with them as far as quality goes. Check them out. You may be surprised. Thanks to Knife Center for their usual excellent selection and service.
