Knife - Essential Tool for Camping, Outdoor Adventure and collection

Extrema Ratio Requiem M390 is an extremely compact, lightweight and effective tactical knife designed for professional use in real-world operational settings. Weighing only 93 grams, it can be used both as a main blade and as a reliable backup knife.

Thanks to a powder metallurgical process, this material ensures high cutting efficiency, excellent wear resistance and remarkable protection from oxidation. The profile is spear point type, with a fuller fuller that further lightens the blade and a false counterbore extended three-quarters of the length. The flat edge sharpening ensures precise and efficient cuts.

The forprene handle, featuring Extrema Ratio's classic ergonomic recesses, ensures a firm grip even under extreme operating conditions.

Requiem M390 comes with an ASPIS hard scabbard, compatible with the M.O.L.L.E. The two adjustable loops allow for secure and customizable installation.

Extrema Ratio Misericordia Desert, which preserves intact all the features of the famous Misericordia model adopted by the 4th Alpine Parachute Regiment, derives from the commemorative dagger made on the occasion of the 140th anniversary of the 4th Alpine Regiment and the 70th since the founding of the Alpine Paratroopers.

It is a tactical-type fixed-blade knife designed for those instances when the knife must be extremely light and compact. The new desert coloring also makes this model available in a shade in line with the most common needs of modern operational departments.

The blade is milled from Böhler N690 steel, hardened to 58 HRC for the best balance of edge retention and strength, is 118 mm long, 4mm thick, and has a flat edge. The weight of the knife is just 87g. The profile is a spear point type, with a full-length shank that makes it even lighter and with a ¾-length false counterblade. The finish is a stone washed type.

The knife's polymer handle features classic Extrema Ratio shells that make for a more secure grip and is attached to the tang by a through-screw. On the rear end the handle flows connecting with a wide ring equipped with a "skull crusher" appendage: a ring that allows the use of martial arts techniques and ensures the hand a very solid grip. In this version the handle is in Desert coloring.

Since this is a knife designed for professional use, much attention has been paid to ease of carrying, accessibility and extraction in case of need. The knife is secured to the sheath by a quick-release safety that can be easily reversed for left-handed use. The sheath is also in Desert coloring, made of high-strength Nylon, very versatile and equipped with 2 adjustable loops that allow it to be attached to M.O.L.L.E systems, facilitating quick extraction in various tactical scenarios.
