The Ant is the most compact among Extrema Ratio's folding knives. Despite its small size, this model features an extremely sturdy, durable, and reliable structure.

The Ant Rescue, unlike other versions, has a cheek piece in red coloration that allows the operator to more easily locate the knife in case of a fall. This version is equipped with a specific serration that allows cutting ropes and even high-tensile aramid materials. Moreover, this model has a tapered tang that serves as an emergency screwdriver. The Ant Rescue has been developed according to the needs expressed by the "Italian Army Alpine Troops School".

The handle is made of two different elements: the cheek piece crafted from anodized anticorodal aluminum and the hardened steel frame which also serves as the blade lock (Frame Lock System). This mechanism involves a part of the frame bending inward to firmly secure the blade in the open position, enhancing the user's safety during the knife's use.

The tang features a hole for the insertion of a lanyard, and on the right side of the handle, there is a steel clip that allows for concealed carry in the pocket.

The Ant is available in 4 versions with two different types of steel, both provided by Böhler, an Austrian company with which Extrema Ratio has been collaborating for over 20 years, using its highly esteemed materials for the production of its blades.

For the Stone Washed M390 version, Extrema Ratio uses Böhler M390 steel, thermally treated to 61 HRC, which, thanks to a powder metallurgy production process, ensures cutting effectiveness, wear resistance, and oxidation resistance over time.

The blade is sheep foot-shaped and has a small hole on the top part to facilitate opening. Its particular structure, with a straight edge, allows the user to comfortably rest their fingers on the back of the knife and use it with ease.

With this exclusive edition of Coltelleria Collini in collaboration with Fox we have chosen to combine the pocket knife Baby Core by Vox with a Japanese powder steel (sintered) and rolled steel (SanMai) by Takefu Steel.

For this project we have chosen to use the Super Gold2 (SPG2) steel at 62/63HRC for the cutting edge of the blade in order to ensure exceptional cutting performance and durability of the sharpening, while ensuring a remarkable resilience and resistance to oxidation given by the lamination process of the blade.

Notes: Design by Jesper Voxnaes - Opening movement on ball bearings - Carson Flipper opening system - Exclusive version by Coltelleria Collini, Sprint Run, with Japanese Takefu Steel SPG2 Rolled Stainless Steel.

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 by famous brands such as Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, etc.

- Longer cutting edge life
thanks to the use of high quality steels with high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the core steel, the blade, once hardened, reaches hardness and cutting performances definitely higher than those reached 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.

The Task series has been designed for all everyday cutting jobs.

The partially symmetrical blade with flat edge on both sides. The hollow part of the blade after the guard, which separates the sharp part from the handle, has been made to house the index finger during use, creating a grip point near the sharp part for better control while using the knife.

This feature, together with the support grip on the back of the knife, allows a better grip while avoiding the slipping of the hand on the blade. This allows you to carry out most cutting jobs with higher pressure.

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.

Intended use: vegetable / meat / fish

La serie Task stata studiata per tutti i lavori di taglio di uso quotidiano.

La lama parzialmente simmetrica con arrotatura piana su entrambi i lati. La parte incavata della lama dopo la guardia, che separa la parte affilata dal manico, stata realizzata per alloggio del dito indice durante l'utilizzo, creando un punto di grip vicino alla parte affilata per un miglior controllo durante l'utilizzo del coltello.

Questa caratteristica, insieme al grip d'appoggio sul dorso del coltello, permette una miglior presa evitando al contempo lo scivolamento della mano sulla lama. In questo modo possibile effettuare la maggior parte dei lavori di taglio con una pressione superiore.
