A beautiful exclusive...
Eric B.
As a repeat customer of BladeHQ I am always on the look out for their numerous exclusive offerings. This one is a true beauty. IMO, the finest looking version of the Kwaiken folder so far.

For an in depth review please check out Baz on Blades at youtube.....

My example showcases beautiful fit/finish rivaling much more expensive knives. Centering is perfect and lock up is without any type of play. The action is a little gritty. But the detent is perfect and satisfying. Not the smoothest flipper out of the box but very acceptable.

Over all I think the price is more than acceptable for what you get in this exclusive offering. The combination of copper, marbled CF and blackwash finish is stunning. The fit and finish on my example is pretty much perfect. And the action, while not the best is very acceptable.
My Prettiest Knife
Shawn F.
This knife is absolutely gorgeous out of the box. My EDC's are all flippers so when I took it out, I was expecting decent action even after looking at reviews. Mine, like many others was a little tight and was a bit tough to deploy. A small loosening of the tension screw fixed that and now this thing flips almost as well as my ZT0450 Sinkevich. It's a gorgeous knife and the patina that the copper is developing already makes this thing really shine. The blade steel could be better for such a price point, but it is a very well built knife and VG10 is easy to put a very sharp edge on. I'm quite happy with it.
Hard to beat
Nathan S.
For a knife at this price point with copper and carbon fiber its hard to beat, the copper is more of a stone washed finish but looks great. Flipper shape isnt the best but if you are used to using a flipper regularly you'll have no problems. IKBS lets the blade fire out, solid lock up, and blade sits flush with the scales when closed.
Fairly dissapointed
Guy K.
I like the copper and carbon fiber, but there's a lot lacking at this price point. Blade steel could be better, finish on CF is milled and kinda dull, worst of all was the action. You would think ikbs would be smooth but it's not.The detent was also not crisp and too soft. Additionally the flipper tab only works with 'light switch' technique, pushing the tab in doesn't allow the blade to swing open as your finger is in the way.
Gorgeous knife with a few flaws.
Adam S.
This is a really good looking knife. I do like the knife, but much like the other reviews mention there are a few cons. First up the positive: very sharp looking and compact design. Overall feeling of quality in hand. Now the cons: action was overly tight out of box. This was easily resolved by backing out the pivot screw a hair. The blade centering is meh. Doesn't rub the liner but comes very close and favors the show side. This could partly be from me backing some tension off the pivot screw but seems more like an overall design flaw. My action isn't gritty but could be better. My expectation is it will improve with use. Overall there is only so much you can expect from a knife at this price point. If you're buying based on looks you won't be disappointed. Action on the other hand leaves something to be desired.
Good looking knife
Sam R.
This is a nice looking knife, i have been thinking of getting a boker kwaiken for awhile now and when this came up I picked one up.

Pros: looks great, compact design, copper bolster and back spacer, and it feels nice in the hand and has a good weight to it.

Cons: Flipping action isnt that smooth, will not fully deploy somtimes, flipper tab looks good but funtion isnt the greatest, blade is not flush when closed, for price blade steel could be better. Pocket clip could be better.

Overall a little expensive for the quality. There are a lot of better made knives around this price range.
Nice Knife
Wes D.
I received my knife a couple of days ago and I really like it. It's robust and weighs more than I thought it would. The knife came reasonably sharp and the action is smooth. I'm happy with my purchase and can recommend buying.
I want to love it, but...
Daryl Y.
First off, I want to say I'm absolutely in love with the looks of this knife. The copper and cf are gorgeous together!
And the blade came razor sharp, nice even bevels.
And that what earns it the stars it gets.
Beyond that though...

First thing I noticed out of the box was a pretty significant (0.011") gap under the cf on the "show side" on the end by the lanyard hole. Looking through the gap I saw something in there that I thought was just a burr or something, so I popped the scales off to fix the issue and found that the 3 screws under the scales, connecting the liners together between the backspacer were not properly countersunk to sit flush with the surface.
On a brand new $150 I probably should've returned it right then, but instead I ground the heads so they would sit flush figuring it would solve the issue.
The gap is smaller now, but not gone, the cf stayed slightly warped to that shape.

Then there was the action, pretty gritty feeling, so I continued dismantling to investigate that. Forewarning: if you take yours apart to clean it, be aware that these are NOT captive bearings.
The grease they were packed in was pretty gunky, but worse is that there appears to be a spot in one of the races where the bearings won't pass freely. They roll a little ways then get stuck.

I haven't solved the issue yet because when I reassembled to test with the new grease I found the final issue:
The heel of the blade sits almost flush with the opening at the spine of the handle.
So, when my finger slipped off what I consider to be a tab that's a little too smooth and too rounded, I sliced my finger wide open.
By the time I got it to stop bleeding I didn't feel like messing with it any more that day... But it's going to mean taking off a fair amount of steel, on an already narrow blade, before it's safe to use.

Oh, one last thing; despite the gritty action, and the rather high force required to overcome the detent with the flipper, the blade will still shake open pretty easily. So it's a no-go on legal carry in places that have strict gravity assist laws
George P.
Wow! what a beautiful knife! The materials are gorgeous and the fit and finish are spot on. Good detent and a sharp blade make this a near-perfect gentleman's carry.
The only gripe is that the action is stiff and gritty. I own other kwaiken versions and they are far smoother out of the box. Hopefully, the action improves with time and use.
Boker Kawiken marble carbon fiber / copper

This is my first Kawiken but it will not be my last. I was very impressed with this knife. Love the copper and the marble carbon fiber is out of this world . Great job Boker keep up the good work .
Well built beauty
Jeremy B.
This knife is nothing but the best and for an affordable price! Buy it. No regrets here!
"Only" as good as expected
Russ G.
This is the second of two kwaiken exclusives that BladeHQ has dropped in the past month or so, or I should say, the second of two manual action kwaikens, as BHQ also released a couple exclusive blue-colored autos (they're really pushing the kwaikens this year; no complaints from me).

In any case, it's natural to compare the two, and surprisingly, I find I actually like the first model, with the brass bolsters and micarta scales, a bit better. Don't get me wrong this one is BEAUTIFUL: copper and marbled carbon fiber are two of my favorite knife materials, so I'd been looking forward to this one since I first saw the pics, and it lives up to expectations all the way. But I wasnt so sure from the pics that I would like the brass/micarta model, and was blown away when I actually saw it; it's just as good looking as this one. And those expectations partly account for my present views: this model lived up to very high expectations, where as the first model greatly exceeded much more moderated expectations. And it's always nice to be pleasantly surprised.

There is one more concrete reason I like the brass and micarta kwaiken a bit better though, and it is actually related to the micarta scales. Compared to these carbon ones, they are a little thicker and a lot more rigid--you can see the carbon scales flex inward a bit when gripping the knife. When I first deployed the blade on this new model, I thought maybe I'd gotten one with a sticky action, which was a surprise considering the IKBS. It just didn't open smoothly all the way at first, and although it got smoother after a few dozen flips, it still wasnt as smooth as I'd have liked, and the blade failed to fully deploy about one out of four/five tires. I finally realized the problem was that I was gripping it to firmly and too close to the lock, which as squeezing the blade and preventing it from opening. This wasnt a problem with the micarta scaled kwaiken because those scales, being firmer, did not flex inward and put pressure on the frame.

So with a quick adjustment of the grip the issue was solved, and it was a minor one anyway. I unreservedly recommend this knife...unless you are only planning to buy one of the BHQ exclusive kwaikens. In that case--but only in that case--I'd say skip this one and go for the other with the brass and micarta. But at $139 and $149 (and free shipping if you're not lucky enough to pick them up in-person like me), you can afford both. And then you don't have to make that difficult choice, because both really are well-built, beautiful knives--truly functional pieces of art.
