Spyderco’s Sage Series™ is a unique family of knives that showcases the innovative lock mechanisms that have helped define modern folding knife technology. Featuring the same basic design parameters for every knife in this series—a full-flat-ground, leaf-shaped CPM® S30V® blade, an ergonomic handle design with textured forefinger choil and thumb ramp, and a reversible tip-up wire clip. However, each knife is distinct in that it highlights a specific lock mechanism and acknowledges the trendsetting knifemaker or designer who invented it.
The Sage™ 5 highlights Spyderco’s own Compression Lock mechanism. Although often mistaken as a “LinerLock on the back of the handle,” the Compression Lock is actually radically different. In a Compression Lock, the blade’s tang ramp faces upward toward the handle’s spine, rather than toward the butt of the handle as in a LinerLock. When the blade is opened, the lock bar is sandwiched between the ramp and the knife’s stop pin. Pressure that challenges the lock is transferred to the width of the bar—not its length—and literally tries to crush it between the blade ramp and the stop pin. This patented mechanism is substantially stronger than most LinerLocks and its location allows the knife to be safely closed with only one hand without placing your fingers in the path of the edge.
