Master at Arms James A. Keating is known worldwide for his Filipino influenced martial arts style and his tactical equipment and training company jamesakeating.com. James introduced Spyderco to a folding knife design he blueprinted to complement his MBC style which he called the Chinook.

The folder has a modified-Bowie-shaped blade and an MBC rated locking system so the knife could be used for cutting as well as passing or blocking. These combined features have since taken root with the MBC crowd and additionally found favor with the hard-use camp/hunting/outdoor knife industry.

The Chinook's 3-3/8 inch blade is hollow-ground CPM S30V with an upward sweeping tip and full belly. Inserted between G-10 scales, dual steel liners make a thicker than customary back lock constructing one of the strongest locking systems found on any Spyderco model. There is no sliding forward or backward on the handle because swells on both ends expand making a combination choil/handguard in the front and a pinky shelf at the butt. These expansions work to hold the hand on the handle in either forward or reverse grip. A three-screwed black metal clip is tapped for tip up/down and left/right carry. Made in Golden, Colorado.
