Spyderco® Mantra™ 4 Front Flipper Folder – 3.15" 8Cr13MoV Satin Leaf-Shaped – Carbon Fiber/G-10 Laminate – C274CFP
The Spyderco® Mantra™ 4 Manual Front Flipper Liner Lock Folding Knife (C274CFP) is a highly streamlined, precision-engineered everyday carry (EDC) cutting tool masterfully optimized to combine advanced deployment dynamics with an ultra-lightweight, low-drag pocket footprint. While traditional flipper knives rely on a large, protruding rear tab that catches on pocket hems, creates external clutter, and ruins the clean lines of the handle layout—the Mantra series completely overhauls front-flipper logic. This high-efficiency folder (716104019779) places a low-profile, subtly jimped front tang index extension perfectly inline with an internal ball-bearing pivot, delivering an exceptional, lightning-fast deployment experience for modern gear minimalists and tactical practitioners.
The structural foundation of this Eric Glesser design is built around a beautifully balanced, full-flat ground 8Cr13MoV high-chromium stainless steel blade. Meticulously heat-treated to optimize edge stability, structural toughness, and corrosion resistance, this reliable working alloy responds beautifully to field sharpening tools. The defining technical edge of the C274CFP profile is its specialized **3.15-inch physical cutting edge length nested into a 3.34-inch classic leaf-shaped blade geometry**. Graced with a broad, slicing-optimized full-flat cross-section and an acute utility point, it glides through heavy cardboard, cordage, and fibrous materials without binding. The blade surface is treated with a pristine **satin finish** and incorporates the signature Trademark Round Hole™ for intuitive backup thumb-flicking options.
The true functional highlight of this fourth-generation platform is its structural composite frame and discreet carry weight metrics. The handle features two slim, open-backed peel-ply textured Carbon Fiber/G-10 laminate scales, merging the executive visual prestige of real carbon fiber weave with the absolute chemical resilience and impact defense of G-10. Hidden underneath the face panel is a single skeletonized, nested stainless steel liner that forms the core of a rock-solid **LinerLock mechanism**, textured cleanly for immediate, low-effort thumb closing loops. Outfitted with a reversible deep-pocket wire clip for ambidextrous tip-up carry and weighing a featherlight 1.90 ounces, this refined front flipper delivers absolute mechanical authority for users demanding top-tier utility speed.
Includes: (1) Spyderco Mantra 4 Folding Knife (8Cr13MoV Satin PlainEdge Blade / Carbon Fiber G-10 Handles), Ambidextrous Reversible Wire Pocket Clip, Factory Information Sheet, and Original Spyderco Presentation Box.
*Front-Flipper Pivot Action & Index Guidance: To execute the front-flipper deployment loop with perfect hydraulic momentum, rest your index finger naturally over the textured tang sliver extending slightly above the handle spine when closed. Rather than pushing straight down into the handle core, apply a swift, sweeping thumb-style "pull-back" stroke toward the rear clip line; the low-friction internal ball bearings will instantly translate this rotational force into a snappy lockup.
Key Features
- Refined Front-Flipper Deployment: Subtle, low-profile jimped index tang replaces conventional rear flipper tabs to keep the closed frame completely smooth and snag-free.
- Precision Ball Bearing Washers: Blade pivot core rides on premium low-friction bearing assemblies, ensuring a fluid, glass-smooth flip action right out of the box.
- Slicing Leaf-Shaped Geometry: Timeless 3.15" leaf profile combines an expansive flat-ground cutting belly with a highly control-focused tip for detailed piercing work.
- Featherlight Composite Scales: Rigid peel-ply carbon fiber over G-10 laminate panels establish superb grip traction while dropping total pocket mass down to just 1.9 ounces.
- Discreet Nested LinerLock: Stainless steel lock liner is carved directly into the inner scale wall, cutting down frame width while ensuring stable, zero-wobble engagement.
- Ambidextrous Deep-Pocket Wire Clip: Low-profile wire clip easily swaps between left and right sides, seating the knife deeply and inconspicuously inside your pocket lines.
