KS1870: 1870 Knockout Folding 3-1/4" Plain Blade
The Knockout American made Pocketknife Series features SpeedSafe® assisted opening. It’s equipped with a deep-carry clip and is drilled for quad-carry: tip-up, tip-down, left- or right-handed. The premium features of this knife don't stop there. The blade shape and action are reminiscent of the Hinderer from Kershaw's ZT knife division. The "walk and talk" of this folding pocketknife are amazing. It feels like a tool that will attack and conquer any task. The slim profile means that you can carry this knife in your pocket and it won't remind you all day that it's there. The fame or "sub frame" lockup is ingenious and seems to work very well- at least when they're right out of the box. We like this knife at the KnifeCenter and highly recommend it!
From Kershaw: "Sure, the Knockout pocketknife offers knockout-good looks. But look beyond its awesome exterior to see what’s really special. The Knockout folding pocketknife 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 knife 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."

Pros: Ease of Opening, Pocket Clip, Handle Feel, Weight, Lock Ease of Use, None
Cons: Blade Material, Blade Sharpness
loved it except for the blade steel.
Love the weight, pocket clip and the fact that it doesn't have flipper studs on the blade.Iwas disappointed with the blade steel (Maybe I'm becoming a steel snob) I decided to get the camber instead (v 30 steel).

Cons: Ease of Opening, None
I'm a huge fan of Kershaw, I own about a dozen Kershaws from different pricepoints, & I own 8 ZT knives. My Knockout looks & feels great...but it suffers from the same issue as my Kershaw "Needs Work" model. The blade deployment feels a bit sluggish. The flipper is fine but when using the studs there's a lack of snap & the blade doesn't deploy & lock all the way open. I'm hoping this is a simple issue of new=stiff & the action will smooth out with use. I've applied some high quality weapons-grade oil & it seems to be helping. Otherwise a very clean design i know i'll be happy with.
