Directly derived from military specifications, this folding knife is designed to replace a fixed blade in the most demanding operational situations. To ensure maximum reliability, extremely robust materials, increased thicknesses, and a solid and secure back lock opening/closing system have been used.

A manual safety lock ensures maximum protection during use, drastically reducing the risk of accidental closure. When inserted in the closed position, it also prevents the knife from being immediately used against the operator in the event of theft.

Materials and workmanship
All components are machined from solid blocks using high-precision CNC machines, while assembly, adjustment, and sharpening are carried out by hand. The blade is made of N690 cobalt stainless steel, known for its high mechanical strength, great cutting ability, edge retention, and excellent corrosion resistance. It has a flat grind and a hardness of 58 HRC.

The scales are made of Anticorodal, an aluminum alloy that is highly resistant to stress and oxidation. The tang, made of hardened N690, acts as an effective emergency glass breaker. Screws, pins, and clips are made of burnished stainless steel, while the blade, lever, and tang are protected by Testudo treatment, which is highly resistant to abrasion and oxidation. The scales are black anodized.

Commissioned and officially adopted in 2002 by the well-known 9th Incursor Rgt. “Col Moschin”, this model expresses the quintessence of the pure combat knife.

Inspired by the daggers with asymmetric blade and straight but oriented handle of the Arditi, from which the Regiment draws its vestiges, it has been reworked in a modern key. The center of gravity is strongly set back, the point particularly piercing. It is light, maneuverable and intuitive.

Every new raider gets one, every new raider is trained to use it to the fullest.
