James Williams, the designer of the Hissatsu�, is a former Army officer and martial arts practitioner/instructor with over 45 years of experience. He knows cutlery as President of Bugei Trading Company, producer of fine Samurai swords. As one who has trained tactical law enforcement and military forces for the SureFire Institute, he has developed a unique and powerful approach to unarmed combatives. His system of defensive tactics, known as The System of Tactical Strategy, has its origins in the ancient Samurai military systems as well as the Russian military art of Systema. A key part of this system is the Hissatsu based on an old Japanese design. The unique shape of the blade, made famous by the legendary Samurai warlord Takeda Shingen, provides enormous penetrating power and superior slashing capability in one blade, which works with the natural motion of the body. James arrived at this modern version as a backup weapon for close-quarters combat. This is a focused single-purpose knife for use in anti-terrorist/close-quarters battle (CQB) environments, either as a primary or a secondary weapon to augment the handgun in the hands of trained professionals. The Hissatsu's dual grind Tanto blade is 440A stainless steel, high satin finished. For those who prefer a non-reflective finish, the Hissatsu is available with a black EDP blade or in Desert Tan dress with titanium nitride blade coating.
