The Extrema Ratio Rao is not so much a knife as a feat of engineering. With the customary robust design and precision manufacture the Rao reaches heights of ingenuity never seen before in the arena of knife design. Purposefully crafted for the Folgore 185 RAO (Regiment Acquisition Objects) unit of the Italian Army it is required to perform in environments and over a period of time that most folding knives would not cope with.

The blade is made from N690 stainless steel with a testudo finish, tempered to 58/60 HRC. It is ingeniously double locked open or closed using a threaded hinge attached to the handle with an elastic lace and a slightly more conventional spring loaded, slide bar lock, making it one of the safest knives in the open position in the world. The grip of the handle is specially configured, anticorodal material whilst the extremely tough nylon sheath with leather interior, is designed to take the knife in the open or closed position. A diamond sharpener is also provided in the front pocket of the sheath which is compatable with MOLLE systems.

The blade, because of it’s weight, it’s a real guillotine. The extra safe device is a steel pin to be hand screwed through two holes placed by the guard zone of the massive anticorodal aluminum alloy handle. This device is necessary because of the violence of the chopping performances expressed this uncommon folder.

The presence of this concrete pin between the blade and the user hands is a great psychological assistance to chop strongly and quickly.
The sheath is an essential part of the system. It contain a diamond sharpener and allows the user to carry the knife in open condition, held by a two clip provided lace or in close condition inside the front pocket. The sheath can be hanged to the last generating combat jacket or standard belts thanks to M.O.L.L.E. system.
