Product Description

Spyderco's fourth-generation Mantra delivers the most refined front-flipper action in the series — carbon fiber/G-10 laminate scales, a full-flat-ground blade on ball bearing washers, and a 1.9 oz carry weight that makes most competitors feel like bricks.

The 3.34" blade is ground from 8Cr13MoV — a high-chromium stainless steel widely used in production knives at this price tier for its reliable corrosion resistance, ease of sharpening on basic equipment, and consistent behavior across the full-flat grind geometry. The full-flat grind here is not incidental: it gives the blade a thin, slicing-optimized cross-section that outperforms thicker hollow grinds on fibrous material and produces the clean push cuts that make this knife feel more capable than its steel tier suggests. The blade rides on low-friction ball bearing washers — the same bearing philosophy Spyderco applies across their premium flipper lineup — which is why the front-flipper deployment feels dialed in from the first use. A satin finish keeps maintenance simple and reflectivity low. The Trademark Round Hole™ is present for thumb-deployment as a backup to the front-flipper tang, giving the Mantra 4 two independent opening methods in one blade.

• Blade: 3.34" 8Cr13MoV stainless steel, full-flat grind, satin finish, plain edge — 0.089" stock; 3.15" edge length; Trademark Round Hole™ for secondary thumb-deployment option alongside primary front-flipper tang
• Handle: Carbon fiber/G-10 laminate scales, open-backed construction, peel-ply texture — one scale machined to accept a nested stainless steel liner; skeletonized liner forms the Liner Lock mechanism and is textured for easy lock release
• Deployment / Lock: Front-flipper tang deployment on ball bearing washers — index finger stroke against the textured tang propels the blade open; Liner Lock secures blade fully open with skeletonized, textured lockbar
• Carry: 1.9 oz; 7.5" overall; 4.27" closed; low-profile deep-pocket wire clip, reversible for ambidextrous tip-up carry (left or right side) — Made in China

Ideal For

• Front-flipper enthusiasts — the Mantra series is Spyderco's dedicated front-flipper platform; the fourth generation refines the tang geometry and bearing system to deliver a deployment stroke that is consistently smooth and fast without requiring the aggressive flick of lesser front-flipper designs
• Lightweight everyday carry buyers — at 1.9 oz with carbon fiber/G-10 laminate scales and an open-backed handle, the Mantra 4 is among the lightest capable folders in Spyderco's production lineup; buyers who have been frustrated by the pocket weight of more substantial EDC knives will find this one disappears

The Spyderco Mantra 4 Carbon Fiber (C274CFP) makes the front-flipper format genuinely accessible — refined tang geometry, ball bearing washers, carbon fiber scales, and a Liner Lock that releases cleanly without aggressive thumb placement.
