Based on Kevin Smock's acclaimed custom design, this limited-edition Spyderco Smock Sprint Run supercharges a fan-favorite flipper with CPM REX 121—a legendary tool steel engineered for unparalleled sharpness and industry-leading edge retention. The deep hollow-ground blade sports a sleek bi-directional satin finish and deploys effortlessly via the flipper tab or signature Round Hole, all riding on Spyderco’s highly fidgety Button-Release Compression Lock®. Outfitted with striking burnt orange peel-ply G-10 scales, skeletonized stainless steel liners, and a reversible pocket clip, this rare, high-performance collector's piece is the ultimate fusion of custom engineering and extreme edge performance.
