Directly derived from military specifications, this fold has been developed to replace a fixed blade in use.

To achieve this result, very strong materials, high thicknesses and a solid and safe opening and closing system were used: the back lock.
The knife is equipped with a manual safety device which confers maximum safety in use and reduces the risk of accidental closure in manieradrastica.
The safety device, if inserted in closing, prevents the knife from being turned against itself in the case of subtraction.

Materials and workmanship:

All parts of the knife are machined from high-precision CNC machines, while assembly, adjustment and sharpening are carried out by hand.
The blade is made of cobalt N690 stainless steel, a steel with very high resistance to mechanical stress, cutting capacity, thread strength and corrosion resistance. The grinding is flat and the hardness is 58HRC.
The grips of the handle are in Anticorodal, an aluminum alega with high resistance to mechanical stress and oxidation.
The tang, in hardened N690, is an effective emergency crystals. All screws, pins and clips are in burnished stainless steel. The blade, the lever and the shank are covered with Testudo treatment, very resistant to abrasion and oxidation. The cheeks are black anodized.

After insistent requests from professional customers, Extrema Ratio decided to create a survival tool suitable for every situation.

Hence the Ontos, (from the Greek "la cosa") a pure, robust, heavy but compact field knife. A portion of the blade is serrated to have a part of the knife always sharpened and ready for use.

The nylon thigh sheath with M.O.L.L.E. he remains on the soldier even when in case of withdrawal he is forced to abandon the primary, heavy and tactical equipment. A pocket is fixed to the scabbard, also with the M.O.L.L.E. system, containing a survival kit that makes the Ontos a real survival knife; in addition a fluorescent stick (duration 12 hours) and a diamond sharpener.

The survival kit contains:
* container for water
* water purifying tablets
* nylon lanyard
* mini compass
* candle
* Flint
* wire saw
* fishing kit
* multi-tool
* matches
* needle and thread kit
* razor blade
* emergency whistle
* copper wire
* SOS mirror
* lapis
* instructions for survival (in English).
