I have the 3.5 version of this knife, which has been discontinued. The knife is well made and the blade deploys very well. You will find the knife is a bit heavy for its size. The steel liners are assembled by screws and the scales are screwed onto the assembled liners. After disassembly, I cleaned mine up, polished the pivot area and put some blue medium threadlocker on the screws. The pivot screw is a TORX T6, so you will not want to mess with it often. The blade has a very fine point and you will not want to be rough with it or drop it open onto a hard surface, such as concrete.

Got one of these a while ago and have loved having it. It looks cool closed or open and the action is as good as that on knives costing an order of magnitude more. Mine gets abused and left full of crud so I finally had to service it and found it was easy and simple to take apart, clean, and lubricate as well. This knife is a great example of how design can take something from ordinary and utilitarian and make it excellent and fun.

this is a great knife. I bought them as stocking stuffers last Xmas and they were a hit with everyone. I paid a similar price so there may be equal deals out there because that number doesn’t jump out at me. it is a fantastic knife however

This was my first “nice / brand name” knife... It has a special place in my heart. It’s great for a cheap EDC knife. It’s crazy that fo $10 you get a Kershaw with custom thumb studs and a few other upgrades. I’m buying another just to have one that’s brand new.

$13 dollars at knifecenter.com and you'll have it by the end of the week. No deal here. To add, a lot of people are talking about how they went through 4 of them, and still recommend them. Just buy an Ontario RAT in D2 for about $40 and Save yourself the trouble.

The blade stains after awhile from just being pocketed.

I bought two more on this drop to give away cause their dirt cheap and I like their size.

Dirty pockets, sure, that must be it.
Or, maybe... Just maybe... It's because the blade is 8Cr13MoV, cheap Chinese stainless that is prone to discoloring and corrosion. Just like every other knife that is made of the stuff. No need to be in denial about it, or to white-wash the properties of the knife; it is incredibly inexpensive. The use of this steel are to be expected at this price point, and is much better than some other cheap stainless steels that could have been used.
This knife is an excellent value at this price point, and I've purchased several to give to people.

Kershaw's bead blasted finish has this problem. I've seen corrosion on a Natrix that was still in the display case. I've never been a fan in general because I don't consider scratches to be a desirable feature, so when I purchase one I go one of two routes:
Stonewash—the matte finish is primed for it. Although acid is typically used, bead blasting will produce satisfactory results when tumbled. And you would be surprised by how well the edge holds up in vibrating tub.
True Satin—or bead blasting with a polish. I say true satin because it has that type of appearance, more so than an actual satin. You can achieve this with ultra high grit. I like using a Magic Eraser which is actually a micro-fine sanding block—I've even used it to polish edges. The sponginess of the Eraser will conform to the shape of the blade and ensure a nice even finish. Works even better on handles. Just keep in mind that it is abrading the surface—I had an OCD housemate strip the finish off of a door once.

This was my favorite knife back when I pretty much only bought "cheap" knives. I own several of them. No-nonsense usable blade shape and some nice little details here and there that make a little nicer than your average Chinese-made cheapie. For instance the thumb stud design. Great knife for the price.

I have this knife. I paid $20, and it's still a bargain at $20, so this should be a no-brainer at this price.
