Tactical knife Extrema Ratio Fulcrum Black 04.1000.0082/BLK 17.1cm - 1
Fixed blade Knife Extrema Ratio Fulcrum FH Black 17.1cm 04.1000.0082/BLK
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.

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.

Folding knife Extrema Ratio T-Razor Black 04.1000.0138/BLK 10cm - 4
Sold out
Folding knife Extrema Ratio T-Razor Black 10cm 0410000138BLK
Extrema Ratio T-Razor with black coating. Up to the early 1900s, people commonly carried pocket utility knives. Due to rampant “misuse”, though, laws were passed to the effect that all such knives were to be clipped at the blade-tip, in order to diminish their dangerousness as weapons. Some people then figured they’d get the greatest effectiveness out of the sharp edge of a traditionally flat-point blade shape, and took to carrying straight-razors. Thus, the straight-razor was for a time regarded as a fearsome weapon of self-defense. Such a “misuse” of the common straight-razor inspired our T-RAZOR design. Available versions: T-RAZOR BLACK, T-RAZOR SATIN.
