A large folding tactical knife with our manual safety innovation, it's specifically designed for one reason: to say sayonara to any evil that comes your way in close quarter battle environments. The Otanashi noh Ken(TM) is designed by the venerable James Williams of Encinitas, CA. A veteran and martial arts practitioner/instructor, he knows cutlery-especially the tactical variety. In fact, his knife designs have quickly become mainstays within the military Special Forces and tactical Law Enforcement communities across the globe. So when SOCOM needed a larger, thinner, folding combat knife that was easy to carry and conceal, Williams answered the call.
