Spyderco's Sage Series was created to showcase folding-knife lock mechanisms and their inventors. One of its most successful members, the Sage 5, highlights our own innovative Compression Lock. 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. Founded in 1976, Spyderco is a leading innovator in high-performance knives, known for their signature round hole and ergonomic designs. Trusted by outdoor enthusiasts, first responders, and professionals, Spyderco uses advanced materials like CPM S30V and SPY27 steel to create durable, reliable tools. With a focus on precision and innovation, Spyderco continues to set the standard for quality in the knife industry.
