Spyderco’s Sage Series is a unique family of knives that showcases the innovative lock mechanisms that have helped define modern folding knife technology. Every knife in the series features the same basic design parameters—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. A portion of the sale of every Sage Series folder is also donated to the National Alzheimer’s Association of Denver, Colorado.
