Product Description

Front-flipper folders live and die by one thing: the action. The Spyderco Mantra 4 gets it exactly right — a razor-thin sliver of textured tang standing proud above the spine, one stroke of the index finger, and the blade is open. Fast, repeatable, and refined enough to carry daily without second-guessing it.

The blade is ground from 8Cr13MoV stainless steel — a proven mid-tier Chinese stainless with solid corrosion resistance and enough carbon to take and hold a working edge with regular stropping. The full-flat grind opens the geometry up entirely, making the Mantra 4 an exceptional slicer at any thickness. On the all-black C274GBBKP, the blade wears a black oxide coating for low-reflectivity carry and an additional layer of surface protection. Ball bearing washers deliver a silky, nearly frictionless deployment, and the Trademark Round Hole™ is fully functional as a backup opener for those who prefer thumb deployment.

Key features:

• Blade Steel: 8Cr13MoV stainless — solid corrosion resistance and reliable edge retention for daily carry use
• Blade Grind: Full-flat — opens blade geometry for exceptional slicing performance across the full length
• Blade Finish: Black oxide coating — low-reflectivity carry with added surface protection
• Deployment: Front-flipper primary + Trademark Round Hole™ backup — ball bearing washers for ultra-smooth, fast action
• Lock: Liner Lock — single stainless liner in reverse-side scale, slim profile without sacrificing strength
• Handle: Contoured black G-10, black-coated hardware — 1.9 oz, exceptionally slim and pocket-friendly
• Carry: Reversible deep-pocket wire clip, ambi tip-up — left- or right-side carry, lanyard hole included
• Dimensions: 3.34" blade, 7.5" OAL, 4.27" closed — fourth-generation Mantra refined front-flipper platform

EDC carriers who want a front-flipper that's actually fast and not just a gimmick; minimalist carry buyers who need a 1.9 oz folder that disappears in the pocket; collectors who appreciate Spyderco's fourth-generation refinement of a sleek design that keeps getting better.

Spyderco Mantra 4 C274GBBKP: Frequently Asked Questions

Common questions about the Spyderco Mantra 4, answered by the Knifeworks team.

What steel is the Spyderco Mantra 4 blade made from?

The Mantra 4 blade is made from 8Cr13MoV stainless steel — a mid-tier Chinese stainless with good corrosion resistance and enough carbon to take and hold a working edge. It’s a practical choice for a daily carry folder at this price point, and with regular stropping it performs well for everyday cutting tasks. The C274GBBKP version adds a black oxide coating for surface protection and low-reflectivity carry.

How does the front-flipper work on the Mantra 4?

In the closed position, a small textured tang protrudes just above the spine of the handle. A single stroke of the index finger against that tang — combined with the knife’s ball bearing washers — propels the blade open quickly and reliably. The Trademark Round Hole is also fully functional as a backup thumb opener for users who prefer that method of deployment.

What does the full-flat grind mean for cutting performance?

Full-flat grinding removes material across the entire blade face from spine to edge, creating thin geometry that excels at slicing and push-cutting. It makes the Mantra 4 a noticeably better slicer than hollow-ground or saber-ground folders in the same class — ideal for food prep, packaging, and general daily tasks where cutting efficiency matters more than blade durability under lateral stress.

Does the Spyderco Mantra 4 work for left-handed carry?

Yes. The Mantra 4 features a reversible deep-pocket wire clip that supports both left- and right-side tip-up carry. The Liner Lock is positioned on the reverse-side scale, and the Trademark Round Hole functions as the thumb opener regardless of which side you carry on.

How light and slim is the Mantra 4 for everyday carry?

At 1.9 oz and 4.27 inches closed, the Mantra 4 is one of the slimmer, lighter folders in Spyderco’s lineup. The single-liner construction — just one stainless liner nested in the reverse-side scale — keeps the handle profile exceptionally thin without sacrificing lock integrity. The deep-pocket wire clip ensures it stays out of sight in the pocket.

Is the Spyderco Mantra 4 covered by warranty?

Yes. Spyderco warrants all genuine products to be free from defects in material and workmanship for the life of the product. If a covered defect is found, Spyderco will repair or replace the item. The warranty does not cover damage from abuse, misuse, accidents, neglect, or improper sharpening. Because Knifeworks is an authorized Spyderco dealer, every Mantra 4 purchased here qualifies for full manufacturer warranty coverage. Details at spyderco.com/pages/warranty-repair.
