On December 19, 1941, in Eluet El Asel, about 400 men from the 1st Royal Carabinieri Battalion Paratrooper faced the assault of 4 battalions of Indian troops of the British Army. Jumping from their trenches by launching improvised devices, the "Desert Lions", as Radio London called them, made the defensive line impenetrable by allowing thousands of Italian-German troops to withdraw safely. This was the first page in the long history of Italian paratroopers.

The Tuscania Paratrooper Regiment asked that the Extra Ratio T911 be specifically made as a commemorative knife for its 80th anniversary.

The T911 is a medium-sized folding light and designed for professional use by military operators. It is equipped with a modified spear point blade, flat edge, in Bohler N690 cobalt steel heat-treated to a hardness of 58 HRC, for the best compromise between strength, ease of regrinding and thread hold. The blade is 76 mm long, 4 mm thick, has a stone washed finish and rotates around an adjustable pin which allows to obtain the best fluidity in opening. A brace allows you to lock the pin in the best position.

The handle is in Anticorodal aluminum alloy with high strength black anodized finish and is milled to facilitate the transition from "reverse grip" handle to saber handle.

The blade is opened by means of a pin operated with the thumb. The knife uses a liner lock type blade lock and a safe ensures maximum hold even during heavy use. The safety lever is colored red for better visibility and engages in an advanced position for more instinctive use.

In the handle are integrated a seat belt cutter with easily available and replaceable cutter-type blade, a tungsten glass breaker, a stainless steel knot loosener and a screwdriver for adjusting the pointing optics, in AISI 420 steel. The clip , reversible and fixed at the end of the handle, allows a very deep port in the pocket, for less visibility.

The knife can be dismantled for cleaning and maintenance. With a total length of 194 mm and a weight of 145g, the T911 is easy to wear both in uniform and in civilian clothes.

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.

This line of knives fits between the Basic Folders series and the Heavy Folders series. The typical mechanism of the series is the LINER-LOCK. The overall structure is robust. All knives in the MF series have a rear glass breaker. They also feature the innovation of the adjusting locknut on the blade fixing pivot.

By removing the locknut it is possible to tighten or loosen the central pivot as desired, to achieve the desired opening fluidity. It will be enough to lock the pivot screw with the locknut to fix the adjustment. The hemispherical milling on the handles facilitate the change of grip from "saber grip" to "reverse grip". The clip is reversible.

The BC (Belt Cutter) version features a rear seatbelt cutter with an easily obtainable and replaceable industrial cutter blade. In addition, a slotted screwdriver is inserted inside the handle that allows for the adjustment and calibration of firearm optics. This version is produced with a rough grip to offer a better grip.

ABOUT THE STEEL

More than just a damask, Coreless steel made by Japanese Takefu Steel comes with over 70 layers of VG10 and VG2 stainless steel welded, forged and coated between them so that you can form a lightweight, slim and durable blade with a spectacular damask outer pattern.

The peculiarity of Coreless steel, unlike conventional rolled steel or Japanese San-Mai, is that it does not have a hard core steel that is used for the cutting edge but has both the VG10 and VG2 steels arranged to form the cutting edge so alternating and sequential to each other.

This particular construction gives the blade - compared to the two steels that make it, individually taken - greater resistance to oxidation, higher surface hardness (up to 61.5HRC), 25% more than cutting capacity, 25% more than the wire hold capacity and 25% more resilience making the blade more robust and less subject to breakage.

Thanks to this latest steel, Takefu Steel has been rewarded on Japanese territory for research and development and innovation in the cutting-edge landscape. Coreless steel has already been chosen by major brands such as Kai and Mcusta Zanmai who since 2017 proposed it on their top productions of professional kitchen knives.

This folding knife is projected for those who are looking for sturdiness and reliability of a fixed blade but also for compact sizes. Its N690 steel blade is available with Drop or Tanto point. For standard use the well known liner lock is enough safe. In case of hard extreme works it is requested to insert the steel pin in the proper hole to cross the handle and the blade, obtaining in this way a sturdy and reliable knife as much as a fixed blade. The steel clip can be removed or even placed on the opposite site of the handle by replacing it with the second supplied clip

Chiudibili Extrema Ratio:
Direttamente derivato da specifiche militari,questo apribile è stato sviluppato per sostituirenell'impiego un lama fissa.
Per raggiungere questo risultato sono stati impiegatimateriali robustissimi, alti spessori ed un sistema diapertura/chiusura solido e sicuro: il back lock.
Il coltello è dotato di sicura manuale che conferisce massima sicurezza nell'impiego e riduce in manieradrastica il rischio di chiusure accidentali.
La sicura, se inserita in chiusura, evita agli operatorimilitari o di polizia che nel caso di sottrazione il coltello possa essere rivolto contro di loro.

Materiali e lavorazioni:
Tutte le parti del coltello sono ricavate dal pieno da macchine a controllo numerico ad alta precisione mentre l'assemblaggio, l'aggiustaggio e l'affilatura sono condotte artigianalmente.
La lama è in acciaio inossidabile al cobalto N690,un acciaio dalle elevatissime caratteristiche di resistenza alle sollecitazioni meccaniche, capacità ditaglio, tenuta del filo e resistenza alla corrosione.L'arrotatura è piana e la durezza è di 58HRC.
Le guancette dell'impugnatura sono in Anticorodal, unalega di alluminio con elevate doti di resistenza alle sollecitazioni meccaniche ed all'ossidazione.
Il codolo, in N690 temprato, è un efficace frangi cristalli d'emergenza. Tutta la viteria, i perni e laclip sono in acciaio inox brunito. La lama, la leva edil codolo sono ricoperti con trattamento Testudo,molto resistente all'abrasione ed all'ossidazione.Le guancette sono anodizzate nere.
