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.

Ferrum Rescue is a tool designed for rescue operations, developed in collaboration with my friend Andrea Micheli, military and law enforcement expert, journalist and shooting instructor. Made with a very compact handle, this rescue tool is equipped with 3 blades, each of which has a specific function:

The first and main blade has a thickness of 3 millimeters and is designed to be used for more demanding purposes and to protect the cutting edge of the other two from premature wear. The teeth allow it to cut larger ropes or textile materials, the remaining smooth part has the classic function of a knife. The second blade is a scalpel, which can be used for extremely precise cuts and for emergency first aid interventions. The third blade, on the back of the first, is the smallest of the 3, it has the function of cutting lines, capable of cutting paracord and aramid material.

The interaction of the main blade with the scalpel allows the operator to make a quick emergency cut to free any injured person from his or her clothing.

The line cutter blade and the scalpel are both interchangeable.

Ferrum Rescue has a slim and compact shape, the two anodized anticorodal aluminum grips make up a light, slender and at the same time very resistant handle. It can be housed in a breast pocket, in small flashlight holsters or inside a single loop of the M.O.L.L.E. system. On the back there is also a hard metal glass breaker.

Equipped with a flipper assisted opening system, the blade rotates on ball bearings which allow a smooth and uncertain movement of the blade. This mechanism allows the operator to open the blade quickly and easily, even with just one hand. The locking system adopted is the well-tested liner lock. The reversible clip is positioned on the back.

The reversible clip is positioned on the back.

Note: -

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.

Satre Expeditions, as well as the Satre model from which it derives, is a fixed blade knife of small dimensions, light and extremely resistant. Given its characteristics, it can be used in a wide range of disciplines and uses or as part of an EDC (Every Day Carry) kit.

It has been designed in collaboration with Daniele Dal Canto, Master Advanced F.I.S.S. (Federazione italiana survival sportivo e sperimentale) instructor. In Neck Knife mode, through the use of a 550 paracord lanyard, it is possible to hold it around the neck keeping the knife vertical with the handle facing downwards.

The metal eyelets on the sheath, made of pre-shaped Kydex, allow the application of both the lanyard and the accessory holder. 

The full-tang skeletonized structure, allows you to customize the knife using Paracord as a coating for the handle.

Satre Expeditions uses Böhler N690 steel heat treated to 58 HRC with MIL-C-13924 burnishing and stone washed surface treatment (Dark Stone finish). It comes with a desert-colored pre-formed kydex sheath on which you can attach the Firesteel for lighting fires (provided inside the box).

Japanese steel merges with Italian excellence

For this 2021 collaboration, exclusive to Coltelleria Collini, we have decided to propose a series of best sellers produced by Extrema Ratio. Knives made with the famous San Mai steel produced by the Japanese Takefu Steel. Specifically we have used the carbonaceous V-Toku2 at 62/63HRC for the central plate and the stainless SUS410 for the two external plates, in order to guarantee a very high cutting capacity, penetration and edge holding together with an easy resharpening and maintenance but at the same time the blade has a remarkable resistance to corrosion and an important increase of resilience given by the type of extreme steel and the laminated structure.

Intended Use: Neck Knife / Collector's Knife

Type of production: Industrial
Country of Production: Italy
Blade / Handle: Full, laminated Japanese steel (San Mai) with V-Toku2 (carbonaceous) cutting edge at 62/63HRC and SUS410 (stainless steel) outer cheeks
Blade finish: Satin finish
Blade length: 40mm.
Blade thickness: 3mm.
Total length: 129mm.
Weight: 55g.
Sheath: Kydex, for neck.
Packaging: Cardboard box with Extrema Ratio logos.
Notes: Numbered edition - cardboard box with Extremaratio logos and certificate - the central core of the blade and handle is made of carbon steel so it is recommended to wash/dry the knife very well after each use and protect the steel, during storage, with a light surface of lubricant to avoid rust and oxidation.

As in the ancient swords of the Japanese Samurai.

The rolled steel - imported in Italy by Collini Steel directly from the Japanese Takefu Steel - is based on the ancient Japanese tradition in the creation of the famous Samurai swords. As early as 1100, expert Japanese blacksmiths combined different materials to give Katana swords incredible cutting capabilities combined with previously unknown strength and flexibility. It is thanks to this revolutionary construction technique that the Samurai swords have been preserved until our days becoming one of the most fascinating objects made by man. Following this tradition applied to modern metallurgy, we are now able to have technologically advanced steels already tested and used in cutlery also by famous brands such as Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, etc.

Characteristics of San Mai steel: It is made of different types of metals alloyed together to create a composite that contains and intensifies the strengths of the metals individually taken:

- Longer cutting edge life
thanks to the use of high quality steels with a high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the core steel, the blade, once hardened, reaches hardness and cutting performance decidedly superior to those achieved with the use of traditional steels.

- Greater resilience
Built on the principle of Japanese swords, the multilayer steel is difficult to break thanks to the toughness of the central steel (Core Steel) and the elasticity of the steel used for the lateral coating (Stainless Steel).

- Improved corrosion resistance
The steel used for the outer layers (Stainless Steel) gives the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates, at a galvanic level, a structure that improves corrosion resistance even on the edge.

- Easy machining even after heat treatment
Although steel normally becomes harder after hardening, the lateral steel used in multilayer machining does not lose its softness and allows easy machining, drilling or welding even after heat treatment. For optimum blade performance, cryogenic treatment is recommended.

- Improved aesthetic performance
Knives made of multi-state steel or damask pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.

Helmsman is a knife designed and perfected in every single detail for its primary use in a nautical environment and represents the evolution of the BF2 V model presented on the Amerigo Vespucci School Ship in 2013 and dedicated to the most beautiful ship in the world.

The blade, which reaches a length of 87 mm, has a serration at the base while the tip has a flat grinding that allows symmetrical cutting work with wider support while the stone washed finishing process preserves more from corrosion in a marine environment.

Dedicated to those who are more at ease with a knife with a more classic profile, the VENOM is characterized by a wide, flat main grind.

Less suitable for combat, it is best expressed in field and precision work (thanks to the lower angle of sharpening).

It is a multirole of great utility in hunting and outdoor sports. The profile and the general outline of the blade are inspired by the Italian and Austro / Hungarian battle blades of the first half of the 20th century.

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.
