Spyderco Endura 4 Lightweight Folding Knife CPM SPY27 Blade, Cobalt Blue FRN Handle

The Spyderco Endura® 4 Lightweight CPM SPY27 takes one of Spyderco’s most iconic folders and elevates it with their exclusive, American-made CPM SPY27® stainless steel. Developed through powder metallurgy, SPY27 enhances cobalt-enriched VG-10 by adding niobium, nitrogen, vanadium, carbon, and molybdenum, resulting in outstanding edge retention, toughness, corrosion resistance, and ease of sharpening.

The full-flat-ground satin-finished PlainEdge™ blade delivers clean slicing performance and fine control. Complementing the blade is a lightweight FRN handle in Spyderco’s signature cobalt blue, textured with the brand’s Bi-Directional Texture™ pattern for secure grip. A reliable back lock mechanism and skeletonized stainless liners ensure strength without excess weight.

Like all Endura 4 models, this knife offers versatile carry with a four-position pocket clip, allowing tip-up or tip-down, left- or right-side carry. Compact, durable, and versatile, the Endura 4 SPY27 is a true everyday carry workhorse with premium performance.
