The Knockout OLBLK features an OD green handle and black finished blade.

Itís 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 ďknocked outĒ 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. Itís equipped with the new deep-carry clip and is drilled for quad-carry: tip-up, tip-down, left- or right-handed.

Hard to beat...
Doug V.
Love the black/green combo, 3 way clip option and itís MUSA! For its length it carries small, I prefer left hand, tip up (since my phone is usually clipped into my right pocket). The only thing about it it doesnít make sense to me are the thumb studs, I never use them over the flipper. .
Great knife
Chad R.
I love this knife! Super thin allows me to carry a bigger blade without all the bulk. Deep carry pocket clip and an awesome edge. Its a must have.

By far one of the best EDCs I own. You get great bang for you buck on this. American made, great deep carry clip, great slicing ability. The speedsafe is also great on this knife. Centering is perfect. The steel will take a wicked edge, I just wish Kershaw would upgrade this to CPM 154 like its other offerings. Don't hesitate to pull the trigger should you need a good knife.

Big enough for tougher taskes, affordable, and thin so it carries well. Pick one up for sure.

Knocked Out

As usual, Kershaw built a winner with the Knockout. Super light and slim with a huge blade hiding inside. Razor sharp and ready for anything you throw at it. If you're on the fence, go for it!
My new favorite EDC (over my Griptillian... XD)

This knife is a superb quality knife from a company not necessarily known for higher quality knives.

Start off with the steel and edge, both are amazing quality. The Sandvik steel will hold the razor factory edge for a good long while, and is supposed to be very corrosion resistant, and easy to resharpen. Blade shape has a great cutting edge profile, perfect for EDC.

Flipper is great, as well as Speedsafe assist, the blade deploys flawlessly. Once broken in, it feels like butter, and the centering has also held very true to the center. Another great factor is the classic deep carry clip. The loop-over sits the knife very deep, is easily concealable, and has great retention.

Only mark off on this amazing EDC blade would be the black finish. I think it is a sort of powder coat, and it does show fingerprints and high use areas in different lighting.

The Knockout is the 6th USA made Kershaw that I've purchased. I've only had it a few days but it may end up being my favorite. The most surprising thing about this knife is how light it is. You won't notice it being in your pocket. Zero blade wiggle in either direction and of course the speedsafe opening and Sandvik steel that Kershaw is known for
