CR2906: 2906 Otanashi noh Ken - James Williams Design


As a veteran and current martial arts practitioner/instructor, James Williams knows cutlery—especially the tactical variety. So, it's no surprise that his Hissatsu™ knife designs have quickly become mainstays within the military Special Forces and tactical Law Enforcement communities across the globe.

Whether a folding or fixed blade knife variation, these are focused, single-purpose knives, for use in close quarters battle (CQB) environments, either as a primary or a secondary weapon to augment the handgun in the hands of well-trained professionals.

The Otanashi noh Ken™ was designed by James Williams per a request from SOCOM for a larger, thinner, folding combat knife that was easy to carry and conceal.

The Osoraku style blade, made famous by the 16th century Samurai warlord Takeda Shingen, is efficient and effective. This knife has a longer blade than the Hissatsu™ Folder and yet is slimmer to carry than the popular Heiho folding knife.

The Otanashi noh Ken™ and Hissatsu™ knife designs were developed for exceptional penetrating ability in tactical use situations.

The clip allows deep, inconspicuous, carry and the frame lock design is for strength and simplicity in operations.

James Williams' work with worldwide military Special Operations and his extensive classical Samurai training means that this knife is designed to perform at the highest level, when you need it most.

Long term review
My experience with this knife hasn't been perfect. It was great when new but as it wore in a glaring defect became apparent. Namely, the frame lock leaf spring was not bent properly. With the blade removed from the handle, it didn't even flex over to the mid point between The scales. This left the knife with a loose blade when locked open. The solution was to disassemble it and carefully bend it in more. Once I did that it was restored to function. Once I did this, the knife has been flawless. I shouldn't have had to do it though!People complain about the weight. Those people are morons. Weight gives this knife a lot of authority when used as a yawara stick as well as impeccable follow through on slashes and thrusts. I use a hand lanyard due to tendon damage in my wrist & thumb from an industrial accident. Over several decades, I've developed a fighting style based on lanyard use. The weight of this knife makes for absolutely frightening cuts when flipping my wrist with the knife braced against the lanyard holding on to the lower third of the handle. I also use the lanyard to transition from saber grip to ice pick and this this knife penetrates like no other folder I've seen in that grip. Some people say the tip is fragile. (Also morons) they obviously haven't tested it for themselves. My testing has shown the tip to be strong enough for thumb and lanyard reinforced ice pick grip thrusting even when it hits bone. That being said, I wouldn't pry with it. That would be gross abuse of any folder, though.Aside from CRKT charlie foxtroting the spring, my other minor complaints are that the finish on blade and steel handle scale wears easily, and there's not enough texture on the steel handle scale. I doubt CRKT reads these reviews, but just in case: Cerakote is a thing. DLC is a thing, checking and stippling to add texture to metal are things.

Excellent Value - Solid Defensive Weapon
I am not a collector. I have a ZT0300 that is too heavy at over 8oz, and too thick to carry sometimes. I wanted a lighter, slimmer knife for self defense, in the $100 range. This fits the bill. Its a purpose designed knife. Obvious slashing and stabbing capability. The lock is very tight when you first get it, but keep playing with it, it loosens up great. I've had it a few weeks and its very easy to open and close. The blade was not as sharp as I like when it arrived. I sharpened it on a stone and its great now; it shaves hair very readily. The LAWKS, feature was tight when it first arrived, but it has loosened up well and is easy to enable and disable, although, I cannot imagine having the time to activate it in a defensive situation unless you constantly practice enabling it when you draw the knife and make that part of your muscle memory similar to deactivating a safety on a hand gun. The pocket clip sits on the end and the knife rides very deep. I carry it in my waistband and sometimes its difficult to present rapidly. Practice this maneuver a lot; this is the most important technique to master in a defensive scenario when you're reacting to someone else. The design and handle allows for a wide variety of grips. The knife is long enough to be used as an impact weapon if closed.

The BEST self-defence Blade
I have been looking for years for a self-defence folding blade that didn't look or feel like an EDC pocket folder. While reading a book by one of my favorite authors, Brad Thor, he mentions a knife used by a CIA operative. His description of the CRKT Otanashi Noh Ken made me investigate the knife. I ordered one, and On arrival, I knew it was the blade I had been seeking. Lightweight for the blade length, strong lockup, black. Perfect. Read ACT OF WAR. Great book, and you will buy one for the same reasons I and Brad Thor consider it one of the most deadly pocket weapons available.
