The Spyderco Mantra 4 C274CFP is a slim, lightweight everyday carry folding knife with refined carbon fiber styling and an exceptionally smooth front-flipper opener. Built with a 3.34" satin-finished 8Cr13MoV PlainEdge blade, the fourth-generation Mantra is designed for daily utility work, package opening, light outdoor tasks, and general EDC use.
In the closed position, a tiny sliver of the blade's tang stands proud above the spine of the handle — a stroke of the index finger against its textured surface propels the blade swiftly into the open position. The blade rides on low-friction ball bearing washers and includes Spyderco's signature Trademark Round Hole for additional opening options. The full-flat grind slices cleanly and efficiently, and at only 1.9 oz the Spyderco Mantra 4 C274CFP nearly disappears in the pocket.
The open-backed handle wears two peel-ply-textured carbon fiber/G-10 laminate scales, one machined to accept a nested, skeletonized stainless steel liner that forms the heart of the sturdy LinerLock mechanism. A low-profile deep-pocket wire clip is reversible for left- or right-side tip-up carry.
