Customer Reviews

Great knife
John S. on Dec 20, 2019

It opens just as stated, its Awesome a lot heavier than I thought it would be but still a good carry wieght.

Tyler J. on Dec 19, 2019

When you buy a budget knife the main thing that makes it better than others is ergonomics. This is by far the best ergonomics in any budget knife I've held!

You Can't Go Wrong
Richard M. on Dec 9, 2019

At 31.5% of $63.51 MSRP, it's all good. I like the fact that I can work on my sharpening skill(s) without destroying a $235 knife. I'll use it 'til it looks like a fish filet knife, many moons from now....

Nice price Nicer knife
VANDON W. on Dec 8, 2019

This my not be the highest end knife but it gets the job done. Smooth action with the nice Emerson designing and keeps the sharpness well. Get it now at this price.

Very nice
Tom R. on Nov 25, 2019

Great knife worth every penny.. Blade is very nice, & looks good.. Cuts thin receipt paper outta the box.. The G10 has just enough grip

What A Deal !!
Donald S. on Nov 22, 2019

This knife is of good quality and comes sharp. I have no regrets making this purchase.

Great knife
David o. on Nov 21, 2019

Very solid built knife for the price. Was suprised how well the wave feature works. Very stiff to open but that will change with use. Thumb disc is okay but it feels like it should be down the blade more for me to have better leverage to open. For the sale price on this right now you can not go wrong.

yes, good price for this good knife
PU D. on Nov 20, 2019

everything is perfect except the quick deployment of blade depends on pants...

Great blade for the money
Wyatt T. on Nov 20, 2019

This blade is getting carried over my benchmades and spyderco's. It's comfortable in hand and the fit and finish is phenomnal. tight lockup and great blade centering.

Great Knife - Blade HQ Exceptional
Bill S. on Oct 3, 2019

I have talked with people at Blade HQ and they are an exceptional group of people. I highly recommend this company. Youtube videos are very good - informative and entertaining. The knife was very well made, but met with an unfortunate set of circumstances. Seeing the quality of the knife, I have placed an order for another one.

top recommendation
Michael M. on Oct 1, 2019

This would be my top recommendation for someone on a budget under $40. can't find much better out there and you can't not like the Emerson wave! comes with a great edge didn't even feel it cut me. A great budget frame lock thats impossible to regret purchasing.

Excellent edc
John H. on Feb 23, 2019

This knife continues to please, everyday I carry this knife and it has never let me down.I do liggt maintenance on it and it has never failed.The ease of operation has not changed since the day I bought it.Also with a lite stropping or touch up with a ceramic rod it is still just as hair popping sharp as the day I bought it.So needless to say my absolute favorite pocket knife I own.

Great knife
david h. on Oct 28, 2018

I have had this for two years!! Still carrying it to this day. The knife still opens smoothly, easy to sharpen. Carries a lifetime warranty for most parts. great buy.

Solid budget option
Michael D. on Jan 7, 2018

This knife is well made and can take a beating. The wave opening works very well in most any pocket, and the ergos are good for my hands. If you're wanting to try an Emerson without breaking the bank, this is a great choice.

Had since September 11th great buy
randy s. on Oct 2, 2017

Just a great buy, a nice way to get an Emerson for less money which is nice Great for EDC use or whatever. Thanks to Blade Hq for being the best online knife retailer!

Won me over, instantly
Steve P. on Apr 4, 2017

I went into the store to buy another knife, one that has multiple 5 star ratings. I looked at this knife as a gift for a co-worker. As soon as I felt it in my hand and the smoothness of the action I decided I really needed one for myself as well!!! At this on sale price I couldn't pass it up. I had them put away the more expensive knife, and bought this one. Have already used it a few times and can't believe the edge that it has as well! If you're looking for a smooth action, tight lock, great fit in the hand and pocket for EDC, this is your knife!

Fantastic value
Daniel L. on Jun 5, 2016

This is by far my favorite of the kershaw/Emerson collabs. Smooth action right out of the box, great ergonomics, and excellent fit and finish. The swedge on this knife is what puts it ahead of the others for me. Many of the others in this line have thin, needle like tips, and I was always afraid that I'd snap one off. Not the case with the CQC-6K. It's solid. I also own this knife's big brother, the ZT0560. While the ZT is clearly the superior knife, this one holds its own just fine, and is one hell of a value. Bravo, Kershaw.

A must buy!
Steven M. on May 18, 2015

Highly recommended! So good I bought two!!! Could be a little hit or miss if you get a defective one. I had a couple bad ones sent, but the guys at Blade HQ helped me out real quick! It's more kershaws issue. Emerson works great!

Good for money
Erico M. on Feb 19, 2020

I got this knife at the end of the year sale for $20, which makes it a great deal. The knife itself is just OK, the main attractive is the Emerson wave opening system. The steel is just passable, the screws are not great and at 5oz, it is very heavy for its size. What makes this knife attractive is the 'wave' opening system. it works really well and after a few minutes of practice it works reliably every time. It was a little stiff out of the box (but working fine) and after a couple of drops of KPL oil it got really smooth. In summary, if you are looking for a 'wave' opening knife, than this is a good budget alternative. If not, then i would say that there are better knives in that price range.

Pleasantly surprised
Bryan C. on Dec 29, 2019

This knife is surprisingly comfortable in the hand with a smooth open. I’m not a fan of the Emerson open, but that’s a minor gripe.

Good price and good features
Alberto R. on Nov 22, 2019

This is my first purchase with "Wave" technology. It does take some practice to deployed this knife. The Frame Lock is bit tight and I hope the friction will lessen with break in and use. This is a sturdy knife for the price and I like it.

excellent knife
don m. on Nov 20, 2019

My only complaint is I can't get the screws out of the base to reverse the pocket clip. Have tried heat & WD40 but nothing works.

Good, not great
Aaron R. on Oct 1, 2019

Really great ergos, with a solid wave and even more solid build. The action does leave something to be desired and the centering went out the window when I opened her up and cleaned her.

Good for the money
Robert T. on Sep 16, 2019

It's a solid collaboration that has me wishing for an American version with some slightly better steel. That being said, $25 at the time of purchase is pretty inexpensive. The mechanism takes some practice but can work. I find myself having to exaggerate my movement when pulling out of the pocket to properly deploy. Lock up seems solid and the knife was frighteningly sharp on arrival.

Great first emerson wave
Stephen M. on Aug 24, 2018

This knife was the first one that I didn't buy at a Wallymart. It really turned me on to how cool knives could be before this I thought $20 was a lit to spend on a "tool" but I realized I carry a knife everywhere everyday since this I've purchased a ZT which is the evolution of this knife.

Buy it
Julio P. on Jan 19, 2018

It’s a good knife for the money. A good work knife

Solid knife
Hayden L. on Aug 26, 2017

I love this knife. An Emerson design on a budget. I love everything on this knife except the teflon washers. Bronze washers would've made this knife way smoother and a better value.

Great price, not terribly smooth
Charles C. on Dec 9, 2019

I originally got this when it was still on sale for $25, now it's $20, which is a lot of knife for that price. Also I was excited to get to experience an Emerson (especially the Wave technology) at such a budget price. However, once I received it, it was incredibly stiff to open. I lubed it, but still not much improvement. Finally I decided to loosen it (it's just with a flathead screwdriver), and while it helped the flipping, then the blade center was off, so I had to re-tighten it. Not terribly impressed. I certainly like the concept of the wave and the out of the pocket deployment, but due to the stiff joint, it only works about half the time. I still do practice with it, but I'm fairly disappointed, especially considering I got it as my primary carry, which I still do, since the wave affords it the best utility for self-defense purposes. I've also since learned you can jerry rig sypderco holes with a zip tie to mimic the same sort of out of the pocket deployment.

Replaced Under Warranty - Still Unhappy
Antonio M. on Nov 27, 2019

I originally received this knife and found it very stiff and off centered. In addition the blade was bent new in the box. I requested a replacement and still find the knife difficult to open manually (i.e., using the thumb wheel). The wave deployment however works fine. After disassembling, cleaning, lubing, polishing surfaces, and adjusting I still find the manual action wanting. After seeing some other reviews on Emerson knives including Nick Shabazz’ I understand that this may just be the way the Emerson knives are, and that the poor action is not necessarily due to this version being manufactured by Kershaw in China. I see this knife is on Sale during Black Friday for $19.99 and that’s probably a more realistic value given the overall fit and finish of this knife. My Spiderco PM2 and Benchmade 551-1 blow this knife out of the water and as usual you get what you pay for. The one thing this blade really has going for it is the wave feature. This knife has the potential to be a great knife with better washers or use of bearings and upgraded materials and manufacturing tolerances.

I wish I liked it more
Joshua P. on Aug 2, 2019

There's no arguing this is a good knife, but I will leave my gripes here and maybe it'll be useful to some. It's too heavy for my liking. It's not a particularly heavy knife and just like most knives, you'll grow accustomed to it being in your pocket and forget its there, but if I'm wearing athletic shorts I can't tie in the front I'm battling to keep my pants up with this knife in my pocket. In other shorts or pants, the wave feature is cool and with practice, you can draw the knife pretty efficiently but its been too much of a struggle to adjust my grip after drawing it for it to be a realistic last-ditch effort self-defense tool. The wave has also torn up the corner of my pockets but that's expected to happen with a number of pocket knives. And maybe it's just my pants but getting the knife to open with the wave feature consistently was a struggle and depending on the angle of my pockets, there were times when I couldn't get the blade to open into the locked position but would only open partially which created a hazard for cutting my fingers when adjusting my grip. Additionally, I always keep my knives in the pocket as far to the outside of the pocket as possible but if you want to pull the knife out of the pocket without using the wave feature you cannot do this with the knife in that position. I know all I did was complain here but like I said, it really is a good and reliable knife. It just doesn't fit my needs or wants at this point.

Awesome Collaboration
Kenneth E. on Feb 1, 2018

This knife is great collab between a more budget friendly knife brand (kershaw) and i high-end tactical knife brand. The emerson wave has been featured on a lot of knives such as on the delica and other kershaw models and it works great. This knife is really awesome for edc, self-defense or even hard use jobs. However i took mine apart and accidentally messed with the lock bar and the detent and lock up is really soft. But that does not affect its performance that much. Really great budget and self-defence knife. highly recommended if you want to try out emerson as a brand.

Good for the Price
Robert O. on Jan 21, 2018

This is an okay budget knife. The emerson opener works good. The disc isn't my favorite opening mechanism. Opening with the disc isn't very smooth. A bit big in the pocket.
