Description
The Spyderco C63GP4 Chinook 4 Pln Edge Blk is a master at arms knife designed by James A. Keating. It is a Bowie-style knife with a thick, clip-point blade, a stout back lock mechanism, and a single-position pocket clip configured for right-side tip-down carry. The original Chinook attracted a devoted following among martial artists, self-defense practitioners, and other knife users who valued extreme strength in their cutting tools. The Chinook 4 retains the signature handle shape of the original design, but its leaner, narrower profile offers improved ergonomics, maneuverability, and reach. The Chinook 4 is constructed with skeletonized full stainless steel and is available in black.
Master at Arms James A. Keating was one of the pioneers of modern defensive knife training. A lifelong martial artist with high-level instructor certification in many different disciplines, as an author, videographer, and contributing editor to Fighting Knives and Full Contact magazines in the 1990s, he was one of the first instructors to demystify knife-based personal-defense and offer sound, logical instruction to the public.In addition to his exceptional skills as a practitioner and instructor, Keating also has a keen insight into the nuances of martial knife design and has personally designed a number of highly acclaimed fixed blades and folding knives. After one of Spyderco's founders, Sal Glesser, attended Keating's legendary Riddle of Steel training camp in the late 1990s, he was so impressed that he invited Keating to design a knife for Spyderco. Released in 2000, that knife?the original Chinook folder?was a groundbreaking achievement in tactical folding knife design.As one of the foremost modern authorities on the martial use of the Bowie Knife, Keating wanted to distill the quintessential qualities of the classic American Bowie into an all-purpose cutting tool suitable for everyday carry. The first-generation Chinook did exactly that, boasting a thick, clip-point Bowie blade, an extremely stout back lock mechanism, and a single-position pocket clip configured for right-side tip-down carry. Early production of this distinctive design had blades crafted from CPM 440V stainless steel, while later knives featured CPM S30V blades. All were hollow ground with thick spines for an impressive balance of edge geometry and strength.The original Chinook attracted a devoted following among martial artists, self-defense practitioners, and other knife users who valued extreme strength in their cutting tools. Although impressively strong, the first-generation design was also somewhat heavy, so in 2003 Spyderco refined it to yield the Chinook II. Its hollow ground blade had an even longer concave clip point and was paired with a narrower handle that accommodated a four-position pocket clip. Three years later, the Chinook was once again revamped to yield the Chinook 3, which featured a full-flat-ground blade with a distal taper to further reduce its weight and enhance its deft balance.Despite their improvements, the Chinook 2 and 3 were still heavy for folding knives and did not fully realize Keating's dreams of a light, exceedingly fast folding Bowie. The reason for their weight was to support the back cuts?inverted, clawing strokes with the tip of the blade?that Keating used in his Bowie Knife system. To withstand the rigors of these tactics, the knife needed an exceedingly strong lock. While the stout back lock used in the original versions definitely met this challenge, it also required the knife to be rather heavy.In 2014, Spyderco introduced the PowerLock in the impressive Tatanka model. The extreme strength of that lock immediately inspired thoughts of incorporating it into other designs?including the venerable Chinook. That powerful combination proved to be the key to realizing Keating's original visions for the Chinook design and inspired the Chinook 4. Leaner, sleeker, and quicker than its predecessors, the Chinook 4 truly realizes the original intent of Keating's landmark design. Its sinuous lines are highlighted by its dramatically swept clip point blade, which is crafted from American-made CPM S30V stainless steel. Its full-flat grind creates a distal taper and impressive edge geometry while enhancing the knife's quick, lively balance. Although the concave clip is not sharpened, when supported by the high-strength PowerLock, it is still capable of the cat-like back-cut tactics that are characteristic of Keating's Bowie method.Although the Chinook 4 maintains the signature handle shape of the original design, which brackets the hand for a rock-solid grip, its leaner, narrower profile offers improved ergonomics, maneuverability, and reach.
