Just by looking at this knife for the first time, you know it's a professional tactical tool to defend yourself. After world-famous knife fighting expert Jim Wagner trained Germany's top counterterrorist team, GSG9, in knife tactics, we at Boker asked him if he would design the ultimate tactical folding knife for police, military and security personnel, and this is the result - the Jim Wagner Reality-Based Blade. This knife has tactical features that no other folder has - a gladius penetrating tip, a cutting kriss curve, two blood grooves in the blade, ergonomic finger grooves with anti-slip texturing, and a Thumb Guide Slide that guides the operator's thumb to the thumb stud for immediate deployment. Also featured is a clip kit that allows the operator to choose between a standard heavy-duty window-breaker or one that looks like an ordinary writing pen clip for undercover operations where conceiling the knife, and yet having instant access, is crucial. It has two lanyard holes for air, water and wilderness operations, and it comes in tactical subdued black. When the blade is retracted, the handle and exposed blade back is designed to be a tight impact weapon. To absorb the tremendous forces you can put to the knife, there is a solid lock back mechanism. Under the fiberglass-reinforced plastic, there are two 1 mm stainless steel liners to strengthen the construction and to give the right weight to the hand. The blade is made of 440C high performance stainless steel, which guarantees superior edge-holding ability and corrosion resistance. Not only does this weapon bear the name of the designer, but the blade is also emlazoned with the name of the fastest growing and most complete martial arts system in the world, Reality-Based Personal Protection. Jim Wagner's system has been taught to the American FBI, Brazilian GATE, Argentinean GOE, Israeli Special Forces, German Federal Police, Canadian Royal Mounted Police, and the list goes on. All the experiences the designer had during his several police and military missions were put into the concept of this knife. Overall length 9 1/16". Blade length 3 7/8". Weight 6.2 oz. Partially serrated blade.
