Product Description

The Spyderco Smock Sprint Run in Burnt Orange G-10 is one of the most steel-forward limited releases Spyderco has produced — a 3.39-inch hollow-ground blade in CPM REX 121, a cobalt-bearing, high-vanadium tool steel engineered to deliver edge retention beyond what conventional high-alloy stainless steels are capable of, housed in Kevin Smock's signature Button-Release Compression Lock design.

CPM REX 121 occupies rare territory in production knife blades. Formulated by Crucible Industries, it is a high-vanadium, cobalt-bearing tool steel designed to bridge the performance gap between high-alloy steels and carbide materials — delivering exceptional sharpness and edge retention that outlasts CPM-S90V, M390, and virtually every other production blade steel available today. The cobalt content stabilizes the steel's structure at high hardness without sacrificing toughness, and the deep hollow grind on this blade maximizes the steel's slicing geometry — producing a fine, acute edge that cuts with the efficiency the steel's hardness enables. The bi-directional satin finish adds visual contrast and reduces drag through cuts. At just 3.8 oz and 0.118" blade thickness, this is a remarkably light carry for the cutting performance it delivers.

• Blade: CPM REX 121, deep hollow grind, drop point profile, bi-directional satin finish, plain edge — 3.39 inches of cobalt-bearing tool steel with edge retention beyond conventional high-alloy stainless
• Handle: Burnt orange peel-ply-textured G-10 scales on skeletonized full stainless steel liners — distinctive color, aggressive texture retention, reduced weight without sacrificing rigidity
• Deployment / Lock: Spyderco Trademark Round Hole plus understated flipper opener, Button-Release Compression Lock — Spyderco's first Button-Release Compression Lock model, enabling one-handed opening and closing simpler than any standard Compression Lock; fully ambidextrous
• Carry: 3.8 oz, reversible hourglass clip for tip-up left or right-side carry, 4.53" closed length — Sprint Run limited availability

Ideal For

Steel enthusiasts and advanced collectors who have worked through CPM-S90V and M390 and want to experience what a cobalt-bearing tool steel feels like in daily carry — CPM REX 121 is not available in any standard production Spyderco lineup. Buyers who want the Smock platform's Button-Release Compression Lock in a limited Sprint Run expression that won't be restocked. Left- and right-handed carriers who need a reversible clip setup out of the box with no aftermarket modification.

CPM REX 121 in a production folder is a rare thing — in a Sprint Run with Kevin Smock's Button-Release Compression Lock design, it's a carry piece that belongs in any serious collection.
