ExtremaRatio - Waki Black Machete Knife - Tactical Knife

The Waki Black comes with a cordura, military-derived scabbard that ensures safe carrying of the razor-sharp blade and its protection from shocks that could reduce its efficiency. The scabbard is also equipped with the MOLLE system that allows it to be carried on tactical vests and general belts.

ExtremaRatio - Sethlans Expeditions - Survival Knife - 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.

ExtremaRatio - 185° RAO - 2018 Version - heavy folding knife
New version 2018 with improved grip: uses the same handle as the RAO II model
Folding knife made to specific requests of the Italian Army department 185 ° RAO (Regiment Acquisition Objectives) and currently supplied to the homonymous department. The supplied knife differs from the civil one only because of the total lack of writing or logos on the blade.
HISTORICAL SUMS ON THE DEPARTMENT:
The 185 ° RAO of the '' Folgore '' is a department with an ancient tradition, but very new. In fact, it was born on April 3, 2000 following the reconfiguration of the 185th terrestrial paratroop artillery regiment. Based in Livorno, it is an atypical department of the artillery weapon, currently inserted in the Special Forces basin.Entirely composed of voluntary personnel, the 185th RAO selects its components through the passing of a physical test and a qualification course on modules '' with increasing difficulty ''. The tasks entrusted to the RAO's men are many, but all very delicate: it is about gathering information on enemy objectives and 'passing them' to one's command. More generally, it can talk about '' recognition in sensitive areas ''. '' It is therefore evident - they stress to the Army - that the activity of the acquirer takes place mainly in hostile territory, in small self-sufficient nuclei that act in isolation ''.
RAO paratroopers are specialists in '' infiltration and exfiltration '' techniques and are able to move in the operating area '' for up to 8-10 days without external supplies ''. They know how to 'escape from capture, escape and escape from an' enemy controlled area '' and, above all, as '' identify, determine and evaluate objectives '' of strategic interest. Since 2002, the year of reconfiguration, the 185th Regiment detachments have operated in all the hottest operational theaters: from the Balkans to Afghanistan, to Iraq. Here they mainly carry out surveys for medium and long-range information purposes and for monitoring the area of responsibility of the Italian contingent.

The restyling of the famous "Paratrooper dagger dagger mod.1939", an important piece of Italian military history.
The knife, although borrowing the line, the structure and the proportions of the original, has been strengthened, enriched with functional modifications and made with materials with modern military specifications.
Unexpectedly, the result of these few modifications is an extremely functional and effective dagger, absolutely competitive with the best contemporary military knives.
The sheath is rigid from the ankle, in the typical manner in which the bayonet is carried by Italian paratroopers.
Ceremony belt sheath included, inclined at 45 ° like the original.

La rivisitazione di un classico, il tributo ad un veterano, il restyling di uno dei pugnali da guerra più largamente distribuiti ed impiegati nel secondo conflitto mondiale: il MARK 2.
Prodotto dalle aziende storiche statunitensi, in innumerevoli varianti ma sempre fedele alle specifiche originali del contratto U.S.NAVY nella forma generale, questo pugnale rimane il preferito dei nostalgici e dei tradizionalisti che si affidano soltanto a strumenti “battle tested”.
I produttori si sono spesso cimentati nell’impresa di modernizzare questo pugnale con risultati non incoraggianti tanto che il modello tradizionale occupa ancora una posizione di rilievo nei principali cataloghi.
Extrema Ratio si cimenta in questo ambizioso progetto con l’obiettivo di mantenere le caratteristiche peculiari dell’originale per effettuare soltanto modifiche funzionali mirate all’incremento delle prestazioni.
Acciaio inossidabile al cobalto per la lama, AISI 303 e AISI 304 per le altre componenti, nel manico il Nylon caricato con fibra di vetro ha preso il posto del cuoio a rondelle.
L’ergonomia dell’originale è stata mantenuta ma tutte le parti strutturali sono state sovradimensionate per farne un massivo e performante coltello multiruolo.
A livello concettuale, le modifiche più significative sono mirate a risolvere i tradizionali “punti deboli” del modello originale: la possibilità di effettuare lo smontaggio da campo senza utensili, la punta con profilo Bowie modificato dritto (più facile da riaffilare) e le scanalature sull’impugnatura “a botte”, che aiutano a percepire anche al buio il verso della lama e incrementano geometricamente la tenuta nei movimenti di torsione (effetto cacciavite).
Altre piccole modifiche sono i fori per il laccio di sicurezza (di cui l’originale era sprovvisto) e i fori sulla guardia che permettono di legare il pugnale ad un bastone da usare come lancia da sopravvivenza.
Il tradizionale scolasangue è stato “vigliaccamente” sostituito con il tipico “side groove” Extrema Ratio per motivi che confessiamo essere puramente estetici: a noi piace così…
Il resto, effettivamente, andava bene com’era…e così lo abbiamo lasciato.
Le prime due versioni sono il classico nero Extrema Ratio e il Desert Warfare, quest’ultimo alloggiato in un fodero coyote HCS specificatamente studiato per le SOF.
Il fodero della versione nera è standard, con innesto automatico del coltello, pattella e cinghia cosciale per il fissaggio al fianco, compatibile con sistema MOLLE.4357-D -
