The Ikushi is a very strange Taichung made spyderco and his father, Paul Alexander is a perfectionniste-engineer who got radical new ideas on portable cutlery. Remember the Sliverax ?
My first impression after opening the Knifecenter’s parcel (thank you Howard and Tom for the fast shipment!): wow so slim ! So easy to pocket ! What a great handle to blade ratio !
My friend JD and Pascal introduced me to front flipper with both owning Des Horn and I even was a proud owner of one of them.
The Ikushi is an eye candy. The knife is unique in many ways. It is a tour de force. So let’s quote Spyderco:
“The ultra-slim Spyderco Ikuchi is a radically different approach to pocketknife form and function. Designed by Paul Alexander, a Ph.D. in Mechanical Engineering and a lifelong knife enthusiast, the Ikuchi (pronounced ee-koo-chee and named after a mythical Japanese sea monster) has an elegantly curved handle crafted with full, skeletonized stainless steel liners and stunning carbon fiber/G-10 laminate scales.
In the closed position, the handle’s narrow, open-backed profile completely contains the knife’s blade—except for a small textured section of the tang that serves as a flipper opener. Stroking this section of the blade with an index finger or thumb provides leverage to swiftly pivot it into the open position, where locks securely via Spyderco’s patented Compression Lock™ mechanism. The satin-finished CPM® S30V® stainless steel blade is full-flat ground for exceptional edge geometry and cutting performance and has an acute, scalpel-like point for detailed work.
To ensure discreet carry while keeping the Ikuchi instantly accessible, its handle includes a low-profile, deep-pocket wire clip that is reversible for left or right-side tip-up carry.”
Some user has argued about the point of the blade being able to catch their finger. If clipped to the right pocket, the seam will be against the handle and it is impossible to catch that tip. I can feel that sharp tip with the meat of my finger and I can understand how I could cut myself too. We will see that in future reports.
But first I have asked to Paul Alexander what was is thoughts behind that design.
“I’ve had a version of the Ikuchi in the works for 4-5 years, but only got around to submitting it to Spyderco at the end of 2016. Part of the reason was the non-functional Spydie-hole, which I thought would stop Spyderco from producing it. The release of the Positron and Mantra 2 made me rethink that, and I started to seriously prep it for submission.
The whole design started around the blade shape. My dad has always preferred a narrow blade because it’s easier to turn the blade in the middle of a cut if you are paring, whittling, etc. Most of my designs have had a fairly wide blade, and I wanted to do something that would fit his preferences a bit more. He’s also been partial to the narrow clip blade found on the American traditional muskrat knives, and the Ikuchi blade shape is my version of that. Sticking with the traditional inspiration, I used the toothpick handle pattern as the inspiration, which also kept the entire knife nice and slim. In the end, I suppose the whole thing came out looking like a modernized Laguiole… which is likely the design which originally inspired the American toothpick pattern.
The wheel flipper was a slower evolutionary process that was a collaborative effort with the Spyderco team. Eric had sort of mentioned that he was curious about adapting the compression lock to a flipper opening mechanism when I first started working with Spyderco, and I tried coming up with a handful of options, with this being one of them. I originally had more of a tab-like interface on the flipper surface on the Ikuchi design, and that morphed into the final wheel configuration through iterations and refinement with input and prototypes from Spyderco.
The early phases of that development process got me so excited for the Ikuchi, I adapted the locking and flipper geometry to three other traditional knife patterns and blade shapes I liked, and created a series of knives. I called the series by the working title of the ‘Four Horsemen’, and tried to tap into that theme for the look and style of all four pieces in the series. The Ikuchi was initially code named ‘Famine’, which fit the inspirational traditional pattern’s name and the overall aesthetic of the design. The other horsemen designs are ‘Pestilence’, ‘War’, and ‘Death’, but that seemed too dark of a theme to use for the marketing of the designs, so I officially named them all after different mythological beasts… and that’s how the Ikuchi became the Ikuchi.”
Mine is not as easy to open/fire as I thought.
The detent is quite strong and it can be a hit and miss. I have hurt my index finger and failed attempt to fire open the knife. Not fun.
I wonder if it will get better but not being able to trust the fact to simply open it…
I have asked Paul.
Some beautiful Tour de Force but not flawless. I would be need to be certain the tip of the blade once closed won’t catch anything in my pocket and to be certain I can open the knife easily and not only half of the time. Unless I need to strenghten the tip of my index ?As you can notice this is the first design which can be easily locked to prevent children to play with it.
Also the flipper once open acts as a guard for your finger but not on a design like the Ikushi. I have never trusted a locking system even on balisongs so it is a knife which is intended to be used as a gentle tool: beautiful to admire as an engineer’s dream.
How will it perform in day to day basis ? We will see.

Great review I have been enjoying mine! Do you think your blade is straight? Mine favors one liner over the other. Also I thought people were making too big of a deal about the tip being exposed until I cut myself on it while it was in my pocket. Be careful!
Thank you !
Mine is straight but is not firing as easy as I thought. It is a major issue for me.
That is a problem, does it not fully deploy?
The detente seems to strong but the action is smooth and it fully deploys. But half of the time I’m stuck in closed position.
I think that’s one of the main hangups I have about all the flipper mechanism types. In my hands at least, they aren’t reliable enough for me to want to carry them as an EDC.
I wonder if a couple passes on some sandpaper would be enough to lower the point to where it won’t be able to snag you any longer. Seems like they could have made the handle just a tad bit taller, without sacrificing the handling characteristics.

I got very nice experience with most of my flippers but I do believe it can be regarded as very “aggressive” by non knife people.
I like the Sliverax better as it offers both option of opening.
This review led me to buy one! I like it a lot so far. My tip is buried far enough to be safe. This is a pet peeve of mine, and I am glad to see it is not a problem on this Ikuchi. The flipping action is pretty cool, but I agree that it is not the easiest. For my purposes it is not an issue as I don’t mind opening two-handed. Really cool and unique knife. I like toothpicks and muskrat clip blades and this is a really nice modern version. The blade came very sharp and pleasantly thin at the edge; a very good slicer!
