Specially manufactured for the Fradon Lock Company, this limited-edition Exclusive version of the Spyderco Delica® 4 features a three-layer laminate blade comprised of a HAP40 core and SUS410 outer layers. HAP40 is a high-speed tool steel produced by the powder metallurgy process—an advanced manufacturing method that reduces alloy migration to yield an extremely fine and uniform carbide structure. Generous amounts of tungsten, molybdenum, vanadium, and cobalt in HAP40's alloy mix give it exceptional toughness and high abrasion resistance—key qualities of a superior blade steel. The blade's high-performance HAP40 core is supported by layers of SUS410 martensitic stainless steel, which increase its structural strength and reduce its vulnerability to corrosion. The boundary between these layers is clearly visible just above the cutting edge and is highlighted by the blade’s full-flat grind.

The other remarkable feature of this Delica 4 Exclusive is its handle, which is constructed with full skeletonized stainless steel liners and carbon fiber scales. The smooth finish of the scales reveals the stunning pattern of the solid carbon fiber and is complemented by the expertly blended finish of the handle's perimeter. All other features of this knife are consistent with the best-selling standard version of the Delica 4, including a sturdy back lock mechanism and a polished four-position pocket clip.
