Spyderco Mantra 4 Carbon Fiber Folding Knife – 3.34″ Black Blade with Front-Flipper & Liner Lock

The Spyderco Mantra 4 (C274CFP) is a precision-engineered folding knife that elevates everyday carry to an art form. Building on three generations of refinement, the Mantra 4 delivers a sleek, low-profile design powered by one of the smoothest front-flipper opening mechanisms on the market. A subtly exposed tang tab at the spine lets a single stroke of the index finger send the blade flying open with speed and consistency.

The 3.34″ blade is crafted from 8Cr13MoV stainless steel with a full-flat grind and satin finish, offering an excellent balance of sharpness, edge retention, and ease of sharpening. Low-friction ball bearing washers ensure a buttery-smooth deployment every time, while Spyderco’s iconic Trademark Round Hole provides an additional one-handed opening option.

The open-backed handle features premium carbon fiber/G-10 laminate scales finished with a peel-ply texture for a confident, lightweight grip. One scale is precisely machined to house a nested stainless steel skeletonized liner, which also serves as the heart of the reliable Liner Lock mechanism. The liner’s textured surface makes lock release intuitive and secure.

For carry, the Mantra 4 includes a low-profile deep-pocket wire clip reversible for left- or right-side tip-up carry — keeping the knife discreet yet instantly accessible when you need it.

Whether you’re a discerning EDC enthusiast, a collector, or a competitive edge user, the Spyderco Mantra 4 is a sophisticated tool that pairs function with finesse. Order online at Deep Roots Rifle Co for fast shipping nationwide, or stop by our Eustis, Florida store to see it in person.
