Having a martial arts background, Joshua Swanagon has done some training with the karambit and is a fan of ring style knives and their prowess in combative applications. However, also being an avid outdoorsman, he has found them to be less than ideal as field utility blades. So he set out to make a knife that could combine those disciplines and decided to call it the C.U.T. 4.0 (Combat Utility Tool). It is a combative, ring-knife with a utility style blade for field use. The curved handle and ring of a karambit provide superior comfort during combative use, and a traditional drop point blade profile is ideal in the field. The aggressive tip provides for maximum penetration during combat, allowing the C.U.T. 4.0 to penetrate body armor and heavy clothing much easier, while also being useful for drilling chores during fieldcraft tasks. The C.U.T. 4.0 was designed with professional personnel in mind, but will also make a great EDC for civilians and martial artists who like the diversity of a dual purpose knife. Bio: Joshua Swanagon has studied survival in both urban and wilderness environments in Colorado and Michigan for most of his life, while also adding experience in harsher terrains abroad. He utilizes his experience and years of diverse martial arts and combatives training and real world application as a self-defense/combatives instructor, published freelance writer and Field Editor for various magazines in the fields of knives, survival, self-defense and tactical subject matters.
