Spyderco’s popular Sage™ Series has traditionally expressed the same iconic design with different lock mechanisms, paying homage to the innovative designers who created them. The Sage 5 Lightweight highlights Sal Glesser’s Compression Lock® in a user-oriented format that features a full-flat-ground CPM® S30V® blade, nested stainless steel liners, and lightweight, fiberglass-reinforced-nylon (FRN) scales. The injection molded scales include our signature Bi-Directional Texture™ pattern for an enhanced, non-slip grip and are home to a reversible deep-pocket wire clip that provides discreet tip-up carry on either side of the body. Crucible® Industries’ CPM® REX® 121® is a high-vanadium, cobalt-bearing tool steel designed to offer the greatest wear resistance, attainable hardness, and red hardness available in a high speed steel. Created to bridge the performance gap between high-alloy tool steels and carbide materials in demanding industrial applications, when applied to knife blades, it offers extreme hardness and unequalled edge retention. This unique expression of the popular Sage 5 showcases REX 121’s remarkable properties in its full-flat-ground, satin-finished blade. To further distinguish its elite status, it also features distinctive burnt-orange-colored peel ply-textured G-10 scales. All other features of this knife are consistent with the proven Sage 5 platform, including nested, skeletonized stainless steel liners, a high-strength Compression Lock® mechanism, and a reversible wire clip that supports ambidextrous tip-up carry. This unique expression of the Sage 5 takes that proprietary theme to the next level with a blade crafted from CPM® SPY27®. Developed exclusively for Spyderco, this American-made stainless steel offers an outstanding balance of toughness, edge retention, and corrosion resistance. The full-flat-ground blade of this knife takes full advantage of these properties and faithfully maintains all the key features of the Sage 5 platform, including a high-strength Compression Lock, nested, skeletonized stainless steel liners, and a reversible deep-pocket wire clip. Its peel-ply-textured G-10 scales also boast a distinctive cobalt-blue color— one of the signature hues of our CPM SPY27 family. Spyderco will donate approximately 5% of sales of the Sage line to the National Alzheimer's Association Denver, Colorado Chapter.
