Extrema Ratio Folgore Nitrogen Fixed Blade Knife, Nitrogen SW, Kydex Sheath

FOLGORE Nitrogen is for those who understand that space and weight are never optional. When you carry it, you don’t feel it.

When you need it, it’s there.

Developed through a long-standing collaboration with the Italian Army Paratroopers Brigade “Folgore,” and refined through field testing alongside qualified operational personnel.

FOLGORE Nitrogen is a compact fixed blade designed for continuous operational use, where reliability and durability are not negotiable.

The result is a tool built for real integration into your gear: in your pack, on your kit, always ready without ever becoming a burden.

It’s designed to be carried for hours, used often, and never questioned.

The blade, in NITROGEN steel, is compact yet structurally solid, maintaining a reduced thickness without compromising strength.

The drop point ensures precision and control in practical tasks, where reliability must be immediate and absolute.

The handle is optimized in thickness to provide ergonomics, grip, and control even in dynamic conditions.

Completing the system is a sheath with an adjustable textile extension for belt carry and paracord for thigh carry configuration, compatible with multiple accessories for various carry setups:

MOLLE ready: direct attachment via paracord to tactical vests, plate carriers, and modular packs.
Clip: fast and discreet carry-on belt or pocket.
Ulticlip: secure attachment without the need for a belt, ideal for technical clothing.
Malice Clip: solid anchoring to MOLLE systems for extended operational use.
Belt Clip: traditional, stable belt carry.
Shoulder harness: concealed and balanced under-garment carry

A modular platform designed to adapt to the mission, the operational environment, and the user’s preferences.
