It’s a Knockout in more ways than one. The Kershaw Knockout looks great, but the reason it bears this name is that a piece of the lightweight aluminum handle has been “knocked out” and inset with a stainless-steel plate to create a frame lock called the Sub-Frame Lock. You get the lightweight benefits of aluminum handles and the strength of a steel frame lock with integral lockbar stabilization. The Knockout also features SpeedSafe assisted opening. It’s equipped with a deep-carry clip and is drilled for tip-up/tip-down carry.

Good but...
Ken D.
I've had this knife for a few months now, carried it for a few weeks and used it to cut everything under the sun. I think it's a decent knife but I do have a few gripes...

The frame is quite slippery, the spine of the knife is chamfered on both sides so holding it square while sharpening presents a challenge and there's absolutely NO jimping on the knife's body or blade.

I was worried this knife would be too large for EDC, but it's so light and slim that I don't even feel it in my pocket. The blade is great and holds a razor sharp edge. As other have mentioned, it opens and locks with a very satisfying "kachunk" almost like racking the slide on a pistol.
Great EDC

This knife is a nice thin light knife, but also has a strong lockup and great blade shape.

would recommend.
Best Carry Knife Out There
Branden R.
Love this knife. Such a positive and solid "click" when flipping open with either the flipper or thumb studs. Great stone washed finish on the blade paired with a unique modified drop point shape. Very lightweight, yet super strong and balanced when flipped open. Has a lot of real estate for those with larger hands (like me), and yet it doesn't feel like it's too large, awkward, or unwieldy. I can see why so many people love this knife. I love it. Nothing bad to say about it. It's my current EDC and I'd be OK if I never own another knife to fit that bill.
