James Williams is actively involved in teaching Military special operations and government security professionals who must at times perform their daily high risk duties in environments where carry of firearms or larger knives is impermissible. It was at their professional request that these close quarter knife designs were developed. The result of this request is the CRKT Heiho. The distinctive blade shape is classical Samurai which gives outstanding penetrating power as well as slashing performance. A stainless steel Inter- Frame build with a liner lock, polished G10 scales, ambidextrous thumb-disk opener, and stainless steel carry-clip round out the make up of this defensive folder. The Heiho makes full use of our patented OutBurst® assisted opening mechanism, and if required, can be quickly disabled easily. The Heiho also incorporates our patented LAWKS safety. This locks the blade in the fully open position making this folding knife a virtual fixed blade. The innovative and patented Veff Serrations are a welcome new addition to the Heiho. Veff Serrations superior rope, fiber, and technical cutting ability is well documented and exclusively offered by CRKT. The Heiho professional folding knife is overbuilt to last. This is arguably as much defensive security as you can find in a small, easily concealed, tactical folder.
