After the great success of the first LKU01 LP “La Prima” and LKU01 models, Extrema Ratio in collaboration with the Master of Arms Danilo Rossi Lajolo of Cossano presents: LKU01 URBAN
available in two color variants:
DARK, burnished blade MIL-C-13924
SIDERAL, blade with Sandblast finish
This model is a perfect combination of refined design and Italian tradition. Characterized by elegant lines that recall the traditional styles of short fencing, LKU01 URBAN is designed to be easily concealable and quick to extract.
The blade in Böhler N690 steel tempered to 58 HRC guarantees a perfect balance between hardness, resistance and resilience.
The quick release mechanism allows immediate opening with a simple movement of the wrist.
The particular characteristic of the LKU01 URBAN is the absence of traditional guards that, in emergency situations, could get caught in the fabric of clothing. In their place, a reverse guard has been designed that sits directly on the blade.
Its characteristic shape guarantees a safety space for the hand in the event of a strong impact and/or accidental closure.
But above all, it transforms LKU01 URBAN into the most compact and concealable “Push Dagger”.
Extremely versatile and functional, it is unmatched in the pointed, controlled cut and short-range combat modes.
The pin, inspired by the bottom of the bullet case, is mounted in a strategic area to allow a quick opening of the knife.
The anticorodal aluminum scales feature a pinstripe pattern that enhances the aesthetics, paying homage to Italian sartorial design. These grooves do not have a merely decorative function. In fact, they allow for an excellent grip and consequently greater safety in extreme use.
The clip, made of stainless steel, is removable and reversible to ensure ambidextrous use.
Its shape recalls a horseshoe in honor of the Italian fighters of the 19th and 20th centuries, who used various lucky objects, including this symbol.
LKU01 URBAN is a folding knife that combines Italian elegance and combat strategy, perfect for those who want to have with them a piece of tradition and modernity, always ready to respond to every challenge with style and reliability.

The CORVO is a traditional Chilean Army combat knife. Its origins are misterious: it did probably arrive in the New World with the Spanish Conquistadores, who had already appreciated it during the war against the Moors. It shows undoubted affinities with Jambiya, the traditional Arab knife still used nowadays as a Yemen male clothing accessory. CORVO has been used during the War of the Pacific. It was produced in several versions such as: the Curved Corvo with the blade bending at almost 90° and the Corvo Atacameño combat knife which is longer but with a gentler bending of the blade for a higher flexibility during use. Extrema Ratio has been inspired by this second version.

Dagger Herring is one of the most loved military knives by the fans. Its original name is Fairbairn-Sykes or Commando Dagger and it was presented in the combat set of the British Commandos.A dagger that enters the history of our country in the Second World War, thanks to the young soldiers exploits of the 1st Reconnaissance Squadron “Folgore”, which were equipped with this weapon during Operation Herring.A dagger that has behind it an heroic piece of history about which little is said, despite the devotion to the cause and the courage of these young boys have written an important page of Italian history.Extrema Ratio wanted to pay homage to this dagger keeping the original design using the most modern production techniques.The unique handmade finish of the handle imitates the ageing of the brass and it gives the dagger a dated look, similar to the original one.The dagger was developed in collaboration with 185th RRAO and adopted as a ceremonial commemorative dagger for the 20 years since the regiment's constitution and 75 years since the Herring mission.Both versions (Herring and Herring NE) are equipped with a polymer case with historical frieze of the Squadrone F, leather / kydex sheath with brass tip and two commemorative scrolls.

MF stands for Medium Folder: a product line positioning itself between the BF (Basic Folder) and the Heavy Folder lines. MF knives employ the LINER-LOCK mechanism and are distinguished for their sturdiness; all are equipped with a glass-breaker. An innovative supplementary screw can be unlocked to enable fine-tuning of the main screw, adjusting opening speed to taste. Hemispheric milling marks on handles make it easier to change from saber-style to reverse grip. Clips are reversible. Model MF0 is “the little one” amongst MF knives – basically a compact version of the MF1. It retains all the characteristics of MF1 but has a downsized handle and shortened blade, similar to our SHRAPNEL “back-up” knife.

Following on from our very successful FULCRUM knife, we at Extrema Ratio developed a bayonet version of that design. Like the original FULCRUM, this bayonet is extremely versatile and strong, capable of sustaining loads of over 150 kilograms. The tanto-shaped blade allows for large amounts of work and wear while still keeping a sharp edge at its exceedingly sturdy tip. This feature, combined with a sharp false edge (in the military versions only), makes the knife retain sufficient combat penetration capability to engage targets covered in heavy clothing, paddings or soft ballistic protections. Thanks to its weight and top-heavy balancing, the FULCRUM BAYONET blade is suitable for hard work on the field.

Extrema Ratio developed the first knife of a new production line, called CONTACT.It has a blade with a lance-shaped profile, a flat grinding and a diamond-shaped geometry. It has got a lower guard branch to protect the hand from accidental cuts, upper jumping to improve grip, a concave fuller along the entire length of the blade and a generous thickness blade (6.30mm) All these details make the Contact the elder brother of the now famous Requiem, revisited in proportions and in some technical features. The first of a new line of multipurpose knives.The blade is made in Böhler N690 steel with a hardness of 58 HRC and a chemical burnishing coating for the Black version. All other colours in production have got a blade with Stone Washed finishing. The handle is still in forprene . It is no more assembled by the side screws but thanks to the shank in truncated cone-shaped stainless steel that is screwed to the bottom and goes to fit inside a special seat, which makes it solid. In this way the knife is well balanced. The sheath is minimalist; most of the fabric has been cut off; it has got a 2nd level retention system, remembering the style of the model it was inspired by.The main shell is injection-molded in shockproof nylon. The secondary retention system is reversible for ambidextrous users. The blade is guided into the sheath thanks to its cone shape that lends itself well to the rapid insertion and extraction of the blade. To extract the blade, a pressure on the trigger will be sufficient, thus releasing the safety that holds it securely in the sheath. In the horizontal slits of the sheath a system is added, which fixes the blade to avoid shaking noises when it is stored inside. The back side of the nylon sheath is M.O.L.L.E. compatible.The textile part is reduced to its minimum and has got the classic two-button safety strap with a belt loop and a thigh band with rubber reinforcement for anti-rotation. Extrema Ratio aims at this new line by minimizing thickness and size of the knife, but not saving on structural strength and safety accessories.

A well-motivated classic. The “kukri”, the Nepalese multipurpose tool made famous by the Gurka Regiment, in service of Her Britannic Majesty and derived from the ancient Greek falcate swords, is nothing more than a machete with an advanced cutting edge. This cutting advancement allows it to replicate the functionality of an axe, while maintaining the versatility of the long blade. Extrema Ratio, managing to blend ancient and modern concepts, has created several tools belonging to this category, among which the KH.
The blade of this machete has differentiated sharpening. Near the handle the blade is razor sharpened, so as to allow the achievement of a narrow sharpening angle without excessively affecting the thickness of the back material which must remain solid. The sharpening at the end of the blade is flat and well angled so as to penetrate wood and vegetation without difficulty.
Usually this type of tool is made of soft steel to be more elastic and easier to sharpen. Extrema Ratio has managed to obtain an elastic tool with a decidedly long-lasting and resistant sharpening by using a hard steel like BÖHLER N690. This machete is equipped with a thigh sheath with a black cordura pocket and a strap for carrying it safely.
KH is available in two variants: BLACK (blade with burnished finish) and SATIN (satin blade).

This project, sponsored by the Italian C.O.F.S. (Comando Operativo Forze Speciali) and its Commander: Gen.Bertolini, was also previously suggested by many international knife collectors.
A restyling of the famous "Pugnale da paracadutista assaltatore mod.1939", a masterpiece of the Italian Military History.
Even if preserving the shape, structure and proportions of the original model, the knife has become stronger and more functional.
New Military Spec materials and processes have been followed in the production phases. Thanks to these few modifications, the 39-09 has unexpectedly become competitive against the best modern tactical knives.
The Ordinan.COFS will be delivered burnished with C.O.F.S. logo and motto with both a hard sheath that is to be dressed at the calf, in the Italian Paratrooper characteristic fashion and ceremonial belt sheat.

The restyling of a classical, a tribute to a veteran, one of the most distributed and used knives during World War II: MARK 2.
It was produced in many versions by historical US knives manufacturers but always following the original specs given by the U.S. NAVY. It is the preferred tool among traditionalists who only trust “battle tested" knives. Throughout the years several manufacturers have tried to restyle this knife with little success. It is in fact the original model which is still favoured in the main catalogues.
Extrema Ratio’s aim, in this ambitious project, is to keep the original characteristics while developing only functional changes to increase performance.
Cobalt reinforced stainless steel is used for the blade, AISI 303 and AISI 304 are used for the other components. The rounded leather handle has been replaced with a fibre glass reinforced nylon handle. The ergonomics of the original knife has been left intact while all structural parts have been oversized to obtain a sturdy versatile knife. The most important changes have been made to solve the so called “weak spots” of the original version.
1. it is now possible to disassemble the knife in the field without the need of tools;
2. the Bowie shape was straightened for easy sharpening;
3. the grooves in the “barrel” shaped handle help to find proper blade direction even in dark conditions
4. the same grooves improve the grip during twisting movements
Other small modifications were to add holes on the back tang to add a lanyard
and on the front guard to tie the blade on a pole to be used as a spear. For purely aesthetical reasons the traditional blood groove has been replaced with the typical Extrema Ratio “side groove”. The original knife was perfect and no other modifications were needed.
The new Desert Warfare version comes with a special HCS coyote sheath specifically developed for SOF units.
