Thanks to its structure, RAO C is a tool that despite its small size, manages to guarantee the same qualities of robustness and reliability as its big brother while offering better portability and manageability.

The locking mechanism on opening is particularly strong as it is assisted by a safety system that turns it into a true fixed blade. The primary safety on the blade is activated by raising and lowering the locking pin. To provide the user with maximum safety in use, a practical and quick secondary safety has been applied, which can be activated simply by moving the locking pin horizontally.

For the purpose of lightening the steel frames, a template was laser-cut from the profile of the RAO C, which was then used to make a gadget that is delivered with the knife.

Sethlans Expeditions, as well as the Sethlans model from which it derives, is a fixed blade work knife designed to deal with a wide range of situations, but also as a backup blade. The Sethlans Expeditions has been designed in collaboration with Daniele Dal Canto, Master Advanced F.I.S.S. (Federazione italiana survival sportivo e sperimentale) instructor.

Sethlans Expeditions has a Böhler N690 steel blade heat treated to 58 HRC with MIL-C-13924 burnishing and stone washed surface treatment (Dark Stone finish). The knife comes with desert colored G10 grips that feature the ergonomic design characteristic of Extrema Ratio handles. They can be removed to free the skeleton structure of the knife, allowing maximum lightness with minimum thickness.

For lovers of extreme customization, the full-tang structure allows the handle to be covered with paracord. The sheath is composed of a very light and minimalist Kydex part. It can be disassembled and can be adapted to both left- and right-handed people. The addition of an optional belt clip allows both vertical and horizontal positioning of the knife and makes the sheath much more versatile than the textile version. It is equipped with a mini pouch with M.O.L.L.E. system containing paracord with flammable filament to be used in case of emergency and/or critical weather conditions and a Firesteel for lighting fires.

Based on the well-known MK-9, designer Dietmar Pohl has developed the new Tactical Nine. Reduced in weight and more compact in size, the Tactical Nine Black is still a full-fledged knife.

The sturdy 20cm long and 6mm thick spear point blade is suitable for a wide range of applications. For high edge retention and blade resilience, the choice fell on the well-known D2 tool steel.

The stonewashed finish creates a scratch-resistant surface and also increases the blade's resistance to corrosion. The step-shaped grip design offers an excellent and secure grip. For powerful or delicate work, the pronounced and also rounded finger recess in front of the guard allows the knife to lean forward. A hidden hole in the end of the handle offers the possibility to mount a lanyard (included).

The Kydex sheath of the Tactical Nine Black has a material thickness of 2.5mm which provides the basis for a well thought out and durable carrying system which fully meets the high demands placed in practice on a tactical knife. A leg strap, infinitely adjustable in size, with snap closure allows it to be fixed to the thigh of the wearer.

Basato sul noto MK-9, il designer Dietmar Pohl ha sviluppato il nuovo Tactical Nine. Ridotto nel peso e più compatto nelle dimensioni, il Tactical Nine è comunque un coltello a tutti gli effetti.

La robusta lama spear point lunga 20 centimetri e spessa 6 millimetri è adatta per un'ampia gamma di applicazioni. Per un'elevata ritenzione del filo e resilienza della lama, la scelta è ricaduta sul noto acciaio per utensili D2.

La finitura stonewashed crea una superficie antigraffio e aumenta anche la resistenza della lama alla corrosione. Il design delle guancette a forma di gradino offorno una presa eccellente e sicura. Per lavori potenti o delicati, l'incavo delle dita pronunciato e anche arrotondato davanti alla protezione consente al coltello di protendersi in avanti. Un foro nascosto all'estremità della maniglia offre la possibilità di montare un cordino (incluso).

Il fodero in Kydex del Tactical Nine ha uno spessore del materiale di 2,5 millimetri che fornisce la base per un sistema di trasporto ben congegnato e resistente e che soddisfa pienamente le elevate esigenze poste in pratica su un coltello tattico. Un cosciale, regolabile all'infinito nelle dimensioni, con chiusura a scatto consente di fissarlo alla coscia di chi lo indossa.

The Extreme Ratio E.C.M. (Einsatzkommando Cobra Messer) is a fixed blade multipurpose knife, designed for operational uses for the famous Einsatzkommando "Cobra" special unit of the Austrian police, whose logo is laser engraved on the heel of the blade. The Extreme Ratio E.C.M. it combines the characteristics of a practical tool and those of a reliable weapon, in a compact configuration with a total weight of 240g.

The blade is made of Böhler N690 steel, hardened to 58 HRC and is 116 mm long, 5 mm thick and equipped with a flat edge. The profile of the blade is of the modified spear point type, with a false counter-thread ¾ in length on the back and a lower guard to protect the hand during use.

Both the guard and the knob have holes to facilitate the attachment of the knife to various tools or for the passage of laces. The blade has a Carbon-based DLC (Diamond-Like Carbon) surface coating making it hyper-resistant to abrasion and chemical aggression.

Given the heavy use of the tool, for the handle, instead of the usual Forprene, the more performing high-strength G10 is used.

It is fixed to the FULL TANG profile by two through screws and maintains all the known ergonomic characteristics of the Extrema Ratio handles. Being a knife designed for professional use, great importance was given to ease of port, accessibility and rapid extraction.

The polymer sheath is versatile and can be carried on a service belt or mounted on M.O.L.L.E. of tactical vests, backpacks or other equipment.

TACTICAL KNIVES MEET THE KITCHEN!
Extrema Ratio is delighted to apply the strict military standards to a range of professional kitchen knives.

The steel blade is the proven BOHLER N690, a steel enriched with chrome, vanadium, molybdenum and cobalt, hardened to the hardness of 58HRC. The handle is made of Forprene, an elastomer that is in the "NATO standard" for resistance to extreme conditions, and is completely removable from the blade; this makes possible a thorough cleaning and maintenance of the knife.

Each knife comes with its own sheath, also of military origin, which does not take into account the rules of hygiene but ensures safe transport dell'affilatissima blade and protection from shocks that could reduce efficiency. We recommend to use it only for the transport and in the event of long periods of inactivity.

Extrema Ratio is proud to present the Culter Venatorius that, so as not to contradict the current address is a technical knife, practical, perhaps a bit 'specialized and that gives a nod to tradition and to the tastes of the most traditionalist hunters who like to do everything yourself.

The Latin motto engraved on the blade reads:

"I am the hunting knife, I am the claw beak and fang of my master. My job is as old as the flesh and blood.", We find that describes significantly the pure essence of the instrument.

We feel to say that if a tool could be capable of humor probably would have added: "It 'a dirty job ... but someone has to do it ...".

The Culter Venatorius, more than a knife, is a complete equipment for slaughtering and skinning of medium and medium-large sized prey, suitable for ungulate hunters.

The kit includes: a knife to slaughter and general use, one skinner provided with cross handle to skin and clean the internal organs the animal, a carver to skin head and snout and a stone with two grains for regrinding of all instruments.

These accessories are contained in the sleeve pocket leather fat-crafted.

The sheath while maintaining the traditional lines, is completely reversible (both the pocket that the passer can be disassembled and applied on the other face of the sheath) and to secure the side which holds the knife has the ambidextrous release. The sheath is handmade by a master saddler leather first-aged choice.

And 'possible to bring the sheath is vertical to the belt connected to the leg, which in a comfortable horizontal position, the shoulder or stopped at the waist with a long belt kit with buckle and snap hooks.

The handle in cocobolo oiled is long enough to allow the use of the knife as a little machete or chopper and thin enough to allow precision cuts.

The blade is in the classic Bohler N690, an excellent steel chrome molybdenum vanadium and cobalt which deserved to become a standard in technical and professional cutlery.

The finish is satin.

The Culter Venatorius is dedicated to all those who wish an Extrema Ratio as batting partner.
