The CRKT Vertex Knife is the result of the company's efforts toward innovative design and exotic materials. CRKT has combined these two thrusts in the Vertex knife line, named for the geometric point where two lines intersect. The Columbia River Vertex Knife features a striking shape submitted by one of the firm's many outstanding designers, that places a symmetrical scale precisely at the palm swell, resulting in a secure and comfortable grip. This CRKT Knife line is built using the same materials a custom knifemaker would: premium blade steel, stainless steel liners, black hard anodized 6061 aluminum scales, and hand-shaped scale inserts of cocobolo wood or resin impregnated fiber. For instant one-hand opening, the CRKT Vertex Folding Knife features the OutBurst assisted opening system with the patent-pending Fire Safe mechanism. When closed, the knife blade is safely locked by the Fire Safe pin and cannot be opened until the safety button on the end of the thumb stud is firmly depressed and the thumb stud is nudged outward. The CRKT Outburst system is both very fast, and very safe, because simply pressing the Fire Safe button does not open the knife. You must both press down and nudge the blade outward deliberately. CRKT Vertex Knives feature custom removable stainless steel clips in a black oxide finish.
