The Caly™ 3 is a highly refined, all-purpose gentleman’s folder that enjoys a near cult following among seasoned Spyderco fans. To celebrate this classic design and give its devoted audience something truly special, we decided to spice it up with a unique, one-of-a-kind Sprint Run edition. This elite expression of the Caly 3 proudly showcases a three-layer laminated blade featuring a high-performance HAP40 tool steel core and SUS410 stainless steel outer layers.

HAP40 is a high-speed tool steel produced by the powder metallurgy process. Containing generous amounts of tungsten, molybdenum, vanadium, and cobalt, it possesses exceptional toughness and high abrasion resistance—key qualities of a superior blade steel. To provide increased strength and corrosion resistance, the high-performance HAP40 core of this knife’s blade is flanked by layers of SUS410 martensitic stainless steel. This unique three-layer construction is evident when the full-flat-ground blade is examined closely, as the transition between the core and outer layers is visible just above the cutting edge.

Like the standard version of the Caly 3, this Sprint Run features a handle constructed with full stainless steel liners, a stainless backspacer, a sturdy back lock mechanism, and a reversible deep-pocket wire clip for ambidextrous tip-up carry. However, to further differentiate it from other versions, this elite Caly 3 Sprint Run features textured green G-10 scales.
