Customer Reviews

slim, stylish, and fun to use
Adam W. on Aug 16, 2020

you kind of have to get this knife to like it. and I like that about it, it feels like the knife that somebody wanted to make, not a knife designed by an AI to be the most functional knife ever. it's not the bugout.

Love it
Gerardo G. on Apr 10, 2019

No blade play. Perfect centering. Smooth action out the box. Love the zippo flipper on it, fast like a flipper but doesn’t chip away at other stuff in your pocket

Kirk B. on Oct 31, 2020

I waited too long to buy this. It's my absolute favorite knife right now. Some things to note: it was significantly smaller than I expected, the detent was very still for the first ~200 opens (seems common issue on forums), the compression lock 'tab' is very very small, and it's even sexier in person. I tried adjusting the detent by disassembling and bending the lock bar slightly but this wasn't the solution, ended up bending it back. It will just take repetition to loosen it up. I found that the best way to open it (if it's stiff like mine) is to use the inside of my middle digit of my index finger, instead of the tip like virtually any other flipper. Fingertips are sensitive and this caused bruising and pain, instead use the meatier part of your finger and it's easy. I know it sounds like negatives but they are minor to me in comparison to the upsides of this wicked little thing. It's such a thin blade that it slices like nobody's business. It's so slender that it disappears in the pocked and it weighs nothing. I honestly mean it when I say that it's my favorite knife, it's that damn good.

Truly unique and special
Gabriel C. on Jul 4, 2019

In an industry where new, never before seen designs make appearances on the daily, the Ikuchi still manages to boldly stand out and deliver a refreshingly different experience that will likely justify its place in your collection even long after the honeymoon phase has gone and passed. It is also incredibly deceptive in its size as well as practicality. Folded it takes up about half the space of a Delica, but it wields a blade that is as long as the PM2, with even more cutting edge and about 0.5in. less handle. The needle like tip along with scalpel like blade can just about maneuver into any task at hand and the carry characteristics are top notch. You will want to bring this everywhere with you. Users who are not experienced in handling very slim knives will get cut, especially with the novel opening mechanism, just a part of the learning process is all it is.

Rudolph J. on Jan 13, 2020

The method of deployment can be rough on the thumb or index finger (tough skin recommended) and once mastered it has a lightning fast deployment. I cut through a few cardboard shipping boxes and it performed like a razor sharp filet knife, proceed with caution as the blade is a painless slicer. Yes I experienced a few nicks. Para 3 is still my EDC but it was cool to change it up with this sleek blade.

Love it!
Jenna E. on Dec 12, 2019

The issue with being able to touch the blade, well it exists but it's so minor. I'd have to press really hard to lightly scratch my finger. These are awesome

Wonderfully Unique Knife
Allen J. on Jan 26, 2020

Now that I have this knife in my possession, I really enjoy it's quirky looks and smooth operation. I didn't know how I would like the wheel flipper but find it very positive in use. Absolutely falls shut when the compression lock is released. Fit and finish are fantastic. The knife is light enough to not pull at my scrubs pockets. I highly recommend this knife.

Took a bit to break in
Robert E. on Nov 10, 2020

I agree with the general consensus for the difficulty with the detent opening at first. I stuck with it and it is breaking in well, getting better and smoother opening action. This is a very nice EDC knife. I must have received a newer one that does not have the problem with the blade tip exposure. I have a number of Spyderco knives and this is up there with the best of them.

I like it very much...
David H. on Apr 14, 2022

Got an Ikuchi, which turned out to be made in Feb. 2019. So, first generation ? Anyway, no matter, as it is in perfect condition...and obviously brand new. The action was a bit stiff, which is apparently the norm for these. However, it is breaking in very nicely...and now (after a few days of fidgeting with it) it drops shut beautifully. The stiffness upon opening has decreased lots...so the knife is now quite pleasant to use. The tip issue did exist with this one, but I fixed that in like 2 minutes. Other details, such as blade centering, sharpness right out of the box, fit and finish, etc....were/ are first rate. I must say, though, I am not a big fan of the "compression lock." Nothing whatever wrong with it...I just find it a bit awkward, when compared to a normal liner lock. Oh well, it's not a deal breaker, by any means and I am getting used to it. Overall, I gave the knife 5 stars...because I do really like it. I had my eye on one of these for some time, but balked at getting one. Now, I am glad I did. The Ikuchi may not be for everyone (personal preferences vary, of course), but I certainly can recommend one, for those so inclined. A beautiful knife, in my opinion.

Finger Saver: Open (CQI)
Peter N. on May 30, 2020

Instead of usingTIP of index finger place !st joint of finger on ball for leverage. Opens with ease. Almost returned till I discovered.

Drop-shut action
Charles F. on Sep 12, 2021

Contacted BHQ and they assured me they had the CQI model, which is what I received. It is impossible to catch yourself on the tip and only if you have long fingernails, like my gf, will the blade nick your nail when it swings closed. Your finger will NOT get cut in the compression lock. Action is excellent. The opening is easy and the lock-up is solid. Like other compression locks, this one drops shut too. But I'll echo others: If you fidget too much, your finger is gonna get sore. Also, might want to ditch the stock wire clip for a Lynch NW replacement wire clip. Before I replaced the clip, the stock clip and the smooth CF laminate sometimes caused the knife to "ride up" in some waistbands, like basketball shorts. Not worth taking a star off, though.

CQI Version
JP R. on Jan 28, 2020

Love this thing. After collecting quite a few spyderco's, my collection has developed a heavy M, PM2, Para3 theme. I wanted something new and different, and this knife's design is a departure from what I normally purchase. While the design of the Ikuchi is unlike anything in my collection, it still feels familiar in action as it retains features like the compression lock, carbon fiber laminate scales, and wire pocket clip. To top off such a compelling package, the price for the Ikuchi is extremely reasonable. This has been the best bang for buck addition to my collection in a while. 10/10, would recommend

Great EDC with class
Daniel R. on Apr 3, 2019

Fantastic EDC! Great balance. The opening mechanism is smooth and easy to use. The handle grip is excellent. Came out of the box sharp as a razor. Ergos are spot on. It has all of this AND it is just a classy looking knife. It has style. Sure a sedan can get you where you are driving to, but why not drive a sportscar???

Unique and well made
Owen K. on Aug 25, 2022

One of Spyderco’s best looking knives. The detent is really stiff out of the box, but mine broke in very well with a few days of fidgeting and practice. Perfect fit and finish. The edge does sit close to the lock when closed, but I don’t think it’s possible to cut yourself on it, as some have complained. I liked the carbon fiber/G-10 laminate more than I thought I would, and it feels better in the pocket than most other knives I’ve carried. A great buy whether you like Spydercos or not.

No Issues
tony o. on Jan 22, 2020

Just received from bladehq-initial examination showed none of the issues previously reported.You CANNOT cut yourself on the tip,it is now ressesed into the handke far enough to fix that,NO side to side,or up or down blade play-rock solid.Blade is perfectly centered.Literally razor sharp.The flipper requires some pressure,but once you clear the detent,it opens with authority-in fact,I would rate the opening as VERY good.The blade falls free,once you disengage the compression lock on closing.My first spydee from their Taiwan factory,and as far as I can see,their reputation is well deserved,(however,I have had no issues with the Golden Co,or the Japan knives either Update-after having this knife for about a year,I've actually edc'd it very little because if your finger has the least bit of moisture on it,it is impossible to open,and having to use that hand sanitizer all the time....I highly recomend this knife anyway,I uae it all the time around the house

Slim Profile Compression Lock
Clint Z. on Sep 6, 2019

The Ikuchi is a very slim knife, that utilizes the compression lock, a feat in itself, with a incredibly designed wheel flipper. The slim profile / wire clip combination is a home run. I am not a fan of the carbon fiber layered G10. I would much rather have the textured G10 or actual carbon fiber. Lastly, because of the slim profile, manipulating the compression lock closed, is slightly more difficult that you'd find on the Para series and Shaman.

Love this knife!
AARON V. on Sep 4, 2020

Very nice blade shape and action. Love the compression lock as it gives it it's fidget factor. I love hearing the blade when it closes. Gave it a 4 stars because my index finger hurt for a couple of days from opening it.

Very Sharp, Hard To Open
David C. on Jan 18, 2020

A little hard to get used to the opening operation, but once open its an extremely sharp and versatile blade.

Beautiful but a beta
Ron J. on May 7, 2019

As will become known, the owners will get pig-stuck by the tip of this blade as its point is exactly at the level of its retraction within the scales. By necessity the knife will be recalled by Spyderco, as they could not do otherwise. One Mersa exposure and it' s all over. In all other respects it is a champion. I re-profiled my tip by a millimeter or so and the problem is solved. CQI, mes frères. It is beautiful, though. Sublime: I adjusted mine and it is drop -shutty, borrowing a phrase.

Tough to open
Cooper P. on Jan 11, 2020

No issues with getting stuck with the knife like others, but it is difficult to get it open. The wheel was very tough and my finger was already thoroughly scratched by the time I had opened it properly for the first time. If I can manage to get it open consistently it will certainly be one of my favorites.

Peter M. on Dec 6, 2019

Positives. Fit and finish are excellent, it's unpolished CF scales give it a nice grip texture that doesn't feel like it will slip. The grind on the blade is something I've not seen from SpyderCo before and I like it. Compression lock is almost always a win in my book, it's elegant, unobtrusive and while not the strongest, more than sufficient. The knife is light, no extra weight here. Negatives. As with other reviews, SpyderCo left the top edge of the blade in direct line with the frame, this is typically a bad practice as it allows for any material or body-part that flows along that edge to be grabbed by the tip of the blade and get poked/cut. This is a serious concern and a tenured company like SpyderCo should know better. A slight change to the curve of the blade or the frame could have completely remedied this issue. Additionally, the knife is ridiculously hard to open "new". I haven't had a chance to break mine in yet, I'm hoping the lock softens up because as it stands I have to use my finger nail to grab the compression lock to release tension enough to get the knife to open. Not a bad, bad thing, but certainly tiresome. The wheel doesn't provide enough grip or purchase to actuate the knife and can leave one with a real pain in the finger. I'll probably keep the knife, but I'm not sure I want to given the negatives.

Wouldn't recommend
Sam c. on Jan 7, 2020

The deployment method isn't consistent. It was difficult for me to deploy the knife and the gear-like wheel would wear on my thumb. A short flipper or similar would've been much better. Otherwise, the scales and size were both great. I enjoy the grippy feeling of the CF and the shiny look. Having the blade flush with the handle when closed is a beautiful design, but too bad the tip could poke you if you rubbed it. BladeHQ helped me with the return after a quick phone call. Great company but can't say the same about the knife.

CQI Version improved but has problems
Alex C. on Dec 30, 2019

This is one sexy knife. Quality and blade is spot on as everyone has mentioned. However there are some design quirks which I believe could have been solved from the onset. 1- I have the CQI version where they fixed the problem of the blade tip catching/cutting when closed. They fixed this by recessing the blade deeper/angled it in more, so that if you run your finger across the liner part where the blade tip is when closed, you will not get cut. 2- As this new CQI version has angled the blade to sit deeper / recessed more, and as it is a compression lock, you actually cut yourself when pressing down the compression lock and doing a swing shut! Lovely looking knife, but tolerances need to be adjusted so you don't cut yourself. Overall a no recommendation from me.

Opening mechanism flawed
Keith N. on Aug 8, 2020

I love the overall design of the knife but the flipper device is too difficult to use. I did not return the knife only because I want it for my collection, if this was going to be my EDC it would rate a zero star for the ability to deploy the blade. I can easily open the knife around 1 out of 50 times IF I hit the sweet spot so it's often easier to press the compression lock to release the detent. I will take knife apart to see if I can make the knife easier to deploy.

If you dont own many high quality blades, you will love it
Christine L. on Apr 8, 2019

Great size, good texture on scales, fit and finish are great too. blade wont cut ur finger during closing compression lock which has good access. it fits really well in hand. Get a benchmade fact, ultratech, or 940-2. If your dead set on Spyderco then change your thinking. Makes a perfect knife for basketball shorts or second edc knife. I wouldnt rely on it solo to do much besides brag about it and impress women that do not know knives. My neice (4) called it cute. That should sum it up

CQI Version
Andrew F. on Dec 5, 2019

I got a chance to check out the newly released CQI version with a bushing pivot and a more recessed blade that won't catch your finger in the closed position. The blade does sit slightly lower in the frame so that issue was fixed. Out of the box the pivot was not fully tightened and the blade would free drop. Tighten the non clip side pivot screw all the way down and the action tightens but there is still a slight amount of side to side play detectable with blade open and lock disengaged. I may be nitpicking but I really don't like side to side blade play. The bushing pivot prevents the elimination of this play. I don't think the action is noticeably different than the original version. I wish they would have used a bearing pivot to achieve a really slick action. It's a wonderful design but let down by the action.

The flipper that does not flip
TAYLOR D. on Oct 10, 2020

I was so excited for this knife. And when I took it out of the box it seemed by excitement was justified. While it does not look ergonomic, it was more ergonomic in my hand than my para 3 LW or 940-1. As far as a locking device, I love a compression lock. Blade was perfectly centered and extremely slicey. However, I went to flip it using the wheel flipper and the detent was so strong I could not get the blade to budge. I nearly tore my finger open trying to get it to open. The only way I could get the blade out was to use the compression lock or put on leather gloves to flip it which actually scarred the leather. It was a $140 flipper that did not flip. Anyway, I decided to give it another chance because everything else was perfect and I have sent it back and purchased another one. BladeHQ was great and gave me store credit so I used it for a replacement. I will update the review once I have the second knife and let you know how it goes. For now, the only reason it is not 1 star is the ergos, fit and finish, quality construction and customer service. Edit: The second knife had the same issue as the first. Extremely stiff detent that would tear skin off your finger if you open more than once or twice. This second one was a little less stiff, so it could be opened without gloves, but it remained problematic. Apparently, this is a generalized issue. The Ikuchi is unfortunately the first Spyderco I would not be able to recommend. Extremely disappointing, because otherwise this would probably have been my favorite knife in my EDC collection.

Watch your fingers!
Lee D. on May 29, 2019

I have to agree with reviewer Ron on this one. I sent mine back the day after I received it because the blade tip took a nip at me when it was fully closed! How an experienced company like Spyderco can produce a product without noticing a major safety issue is beyond me. Very disappointing because I really liked the knife.
