Spyderco Mantra 4 C274GBBKP is a lightweight folding knife designed by Eric Glesser. The model features a Leaf-Shaped blade, 8Cr13MoV stainless steel, and a slim black G10 handle. Weighing just 54 g, the knife is comfortable for everyday carry.
The blade can be opened using a minimalist Front Flipper or via a Thumb Hole. Ball bearings ensure smooth operation of the mechanism, and the Liner Lock stabilizes the blade when open. The open-back design, single recessed liner, and wire deep-carry clip help maintain a slim, lightweight construction.
8Cr13MoV – practical stainless steel for everyday tasks
The blade is made of 8Cr13MoV stainless steel. This material is relatively easy to sharpen, corrosion-resistant, and easy to maintain. It works well for opening packages, cutting cardboard, tape, string, and other lightweight materials.
Leaf-Shaped, Full Flat Grind, and Black Oxide
The Leaf-Shaped profile combines a gently curved cutting edge with a functional tip. Full Flat Grind facilitates smooth gliding of the blade through the material, while the Black Oxide coating gives the blade a subdued, technical look.
Black G10, Liner Lock, and deep-carry wire clip
The handle is made of black G10 with a smooth finish. A single, recessed stainless steel liner reinforces the construction around the pivot and lock without adding excessive weight. The reversible deep-carry clip allows you to carry the knife on the right or left side in a tip-up configuration.

Frequently Asked Questions
How do I care for and sharpen 8Cr13MoV steel?
After use, clean the blade and dry it thoroughly. 8Cr13MoV steel can be sharpened using water stones, ceramic stones, diamond sharpeners, or a sharpening guide system.
How does the Liner Lock work?
The Liner Lock uses a spring-loaded steel inlay that, when the knife is opened, slides under the base of the blade and stabilizes the blade. To close the knife, you must slide the inlay to the side.
What are the Front Flipper and Thumb Hole for?
The Front Flipper allows you to initiate opening from the top of the Handle, while the Thumb Hole lets you open the blade with your thumb through a hole in the blade.
What makes a full flat grind unique?
A Full Flat Grind extends from the cutting edge high up toward the spine of the blade. This geometry reduces resistance during cutting and works well for everyday tasks.
What does “tip-up clip” mean?
A tip-up configuration means that when the knife is closed, the tip of the blade points upward. On this model, the clip can be moved to either the right or left side of the Handle.
