Designed by acclaimed personal-defense expert Master at Arms James Keating, the original Spyderco Chinook distilled the quintessential qualities of the classic American Bowie Knife into an amazingly capable all-purpose folding knife. The revolutionary fourth-generation Chinook 4 not only revives that groundbreaking design, but elevates it to all-new levels of perfection. Leaner, sleeker, and faster than its predecessors, the Chinook 4’s sinuous lines feature a dramatically swept full-flat-ground clip-point blade crafted from CPM® S30V® stainless steel. Its signature handle, which “brackets” the hand for a rock-solid grip, is built with skeletonized full stainless steel liners, a stainless back spacer, and high-traction textured G-10 scales. Longer and narrower than the original handle design, it is also home to a patented PowerLock™—an advanced lock mechanism that combines extreme strength with ultra-smooth operation. A reversible hourglass clip provides convenient left or right-side tip-up carry and a lines lanyard hole allows the easy attachment of lanyards and fobs. They also complement the symmetrical lines and fully accessible Trademark Round Hole™ in the blade to make every aspect of the carry and operation of the Chinook 4 completely ambidextrous.
