Kershaw Knockout Assisted Opening Knife (3.25" Stonewash) 1870


  • Sandvik 14C28N steel drop point blade with a stonewash finish.
  • Flipper tab and thumb studs for SpeedSafe assisted opening.
  • Black aluminum handle.
  • Secure sub-frame lock.
  • Four-way reversible pocket clip.


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. This Kershaw folder also features SpeedSafe assisted opening. It's equipped with the new deep-carry clip and is drilled for quad-carry: tip-up, tip-down, left- or right-handed.

Customer Reviews

Love it
Scott B. on Jan 7, 2018

This was my favorite EDC for some time. It’s made in the US, is slim, light weight, has a deep carry clip and a great blade shape that holds an edge well and is easy to sharpen. I removed the thumb studs because they serve virtually no purpose and for some reason with this knife they would get hung up on my pocket when I’d pull the knife out. I also put some grip tap on the end opposite the clip for traction with my thumb when taking the knife out of my pocket, the aluminum handle is a bit slick, but once in hand and opened I never felt like it slip out of my hand. This knife will remain in my collection.

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. on Jan 20, 2016

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.

Awesome knife!!!!!
Josiah Z. on Feb 27, 2019

This is a great knife all around. I would definitely recommend this knife. there is one fault. The steel isn't that great for an $124 knife. On Blade HQ it is $80 so that makes it a little better, but is dulls out very quick.

Good but...
Ken D. on Feb 22, 2017

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.
