More than a knife, it is a threat extinguisher.

A large resealable tactical knife with the innovative liner locking system, is specifically designed for one reason: to say sayonara to every evil that arises on your path in close combat situations.
Otanashi noh Ken is designed by the venerable James Williams of Encinitas, CA. Being a veteran besides being a martial arts practitioner and instructor, he knows the cutlery, especially the tactical one. In fact, his knife designs quickly became known in special forces and security forces around the world. So when SOCOM asked for a bigger, thinner, reclosable combat flap that was easy to transport and hide, Williams answered the call.
