Product Description
The Mantra 4 C274GBBKP is a slim, lightweight Spyderco front-flipper folder built for fast, smooth one-handed opening. This all-black version pairs a black oxide 8Cr13MoV blade with contoured black G-10 scales and black-coated hardware, at just 1.9 ounces.
8Cr13MoV is a stainless steel known for good corrosion resistance and easy sharpening, which makes it simple to keep a working edge with regular touch-ups. The 3.34" blade is full-flat ground for clean slicing and finished in black oxide for a low-glare look. A small textured tab of the blade tang sits above the spine when closed: press it with your index finger and the blade swings open on ball bearing pivot washers.
- Blade: 3.34" 8Cr13MoV blade with a 3.15" PlainEdge, full-flat grind, black oxide finish.
- Handle: Contoured black G-10 scales with black-coated hardware; 4.27" closed, 1.9 oz.
- Deployment + Lock: Front flipper with the Spyderco Trademark Round Hole as a backup opener, on ball bearing pivot washers; a Liner Lock holds the blade open.
- Carry: Reversible deep-pocket wire clip for tip-up carry on the right or left side, plus a lanyard hole; 7.50" overall.
Ideal for: EDC carriers who want a fast, smooth front-flipper; minimalist carriers who want a slim folder under 2 ounces; and Spyderco fans who prefer a low-glare, all-black knife.

Spyderco Mantra 4: Frequently Asked Questions
Answers to the most common questions about the Spyderco Mantra 4 (C274GBBKP).
What lock does the Spyderco Mantra 4 C274GBBKP use?＋
The Mantra 4 uses a Liner Lock. When the blade opens, a spring section of the stainless steel liner moves across behind the blade tang and holds it open. To close, push the liner aside with your thumb and fold the blade, keeping your fingers clear of the edge as it closes.
What is a front flipper, and how do I open the Mantra 4?＋
A front flipper is a small textured tab of the blade tang that sits above the spine of the handle when the knife is closed. Press it down and forward with your index finger, and the blade swings open on ball bearing pivot washers. The Spyderco Trademark Round Hole in the blade also works as a backup opener with your thumb.
What is 8Cr13MoV steel, and how do I care for the black oxide finish?＋
8Cr13MoV is a stainless steel with good corrosion resistance that sharpens easily, so it is simple to maintain at home. The black oxide finish is a thin surface treatment that can wear at the edge and high points with use. Wipe the blade clean and dry after use, and a light coat of oil helps protect the finish.
What is the Mantra 4 blade good for?＋
The C274GBBKP has a 3.34-inch blade with a 3.15-inch PlainEdge and a full-flat grind, so it slices cleanly for opening packages, breaking down boxes, cutting cord, and food prep. At 1.9 ounces, it carries easily in a pocket all day.

The C274GBBKP ships as a knife with its reversible deep-pocket wire clip installed. It is knife only, with no sheath or lanyard included. Packaging and included items are set by Spyderco and are subject to change.
