Cuchillo Táctico Extrema Ratio Contact Black 04.1000.0215/BLK 16.2cm
Cuchillo de hoja fija Extrema Ratio Contact Black 16.2cm 04.1000.0215/BLK
Contact is a first knife of Extrema Ratio new production line. It has a blade with a lance-shaped profile, a flat grinding and a diamond-shaped geometry. Contact has got a lower guard branch to protect the hand from accidental cuts, upper jumping to improve grip, a concave fuller along the entire length of the blade and a generous thickness blade (6.30mm) All these details make the Contact the elder brother of the now famous Requiem, revisited in proportions and in some technical features. The blade is made in Böhler N690 steel with a hardness of 58 HRC and a chemical burnishing coating for the Black version. The sheath is minimalist; most of the fabric has been cut off; it has got a 2nd level retention system, remembering the style of the model it was inspired by.

Growing demand from the professionals amongst our clients persuaded Extrema Ratio to design a survival tool for all seasons. ONTOS (“the thing” in Greek) is a pure field knife, tough and heavyweight despite its compact size. The serrated segment on the back of the blade is meant as a back-up, never to be caught without a sharp edge ready for use. The MOLLE compatible nylon thigh sheath stays on even in the event of a retreat, when a soldier would drop most of his cumbersome primary equipment. It is possible to buy separately a survival kit to be fixed to knife sheath. Available versions: ONTOS BLACK, ONTOS GREEN.

Cuchillo Táctico Extrema Ratio Fulcrum Black 04.1000.0082/BLK 17.1cm - 1
Cuchillo de hoja fija Extrema Ratio Fulcrum FH Black 17.1cm 04.1000.0082/BLK
For the sake of viewer convenience, the content is shown below in one of the available alternative languages.Probably a milestone among multipurpose knives. Employed on a large scale in Afghanistan as standard equipment by the members of the Italian mission "Nibbio", it is part of an experimental project undertaken by the Alpine Troops Headquarters on the renewal of individual equipment. During the preparation for this mission, the Alpine Troops Headquarters coordinated a team of companies in the realization of a new and complete experimental kit of individual equipment. Extrema Ratio is the company that the Alpine Troops Headquarters chose for the development of a multipurpose knife suitable for the infantry, a knife that could be used in any action and that could successfully solve any type of problem even where more specialized equipment proved inadequate.It was so successful that the multipurpose knife then led to the development of the Fulcrum Bayonet, which had the same characteristics but could be fixed to the issued rifle. The Fulcrum is an extremely robust and versatile knife, the blade can take loads over 150kg without breaking, the point is incredibly robust and the "tanto" profile means the knife can be used for long periods without affecting the sharpness of the last section, this guarantees, together with the partially sharp dorsal blade, (the civilian version does not include this), its capacity for penetration which is necessary in close combat against targets with heavy clothing, garnments and soft ballistic protection. The forward centre of gravity and the weight of the blade make it suitable for heavy field work. The new automatic hard sheath means it can be carried both safely and comfortably and the lace that holds the upper part of the handle dramatically reduces the risk of entanglement, even when making parachute jumps. The speed and facility with which both ordinary and extraordinary maintenance can be carried out help to make Fulcrum an excellent choice for use on a large scale from an economic and administrative point of view.

Boatswain's knife. Thanks to extremely compact shape typical of BF Extrema Ratio models, the extraction of the knife from the pocket becomes easier and it prevents the tool from entangling, a crucial detail in case of emergency. The blade has a flat grinding which allows symmetrical cutting jobs symmetrical with wider support. On the other hand the tip which is thick and durable thanks to the “tanto” version, allows a greater penetration and a more clean and precise cut.The aluminum handle, has the typical "Tactical" structure, already used in the past on the BF models.It has got a pattern of concentric circles giving the handle an additional grip. This structure enables the rinsing of the handle from salt, or organic material, very important considering its primary use in the naval environment. In the central part of the handle its placed a small slot to allow to lock or unlock small wrenches. In the right part of the handle, in correspondence of the liner lock, a steel plate is placed to give a more solid structure to the slot. The BF2 V comes with just one stone washed finishing to find it easier. The same finishing is proposed for the accessories: •reversible clip applicable on both right or left side of handle. •screw regulation system with 12 positions to control the closing and opening of the blade. •marlin sparkle on the tang of the handle with a length of 70mm to untie knots in ropes or thick cords. In opened position it is fixed by a steel mechanism easy to activate and placed inside the handle in order to feel it while handling the knife. It comes with a plastic lanyard with a fix to be fix to the belt, with a joint to allow the different placements and with a quick release simply pushing of the clip button. The length and flexibility of the lanyard allows to work with the tool in the maximum operating area what a shorter lanyard would not allow
