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.

MF1 EVO is available in 6 versions with two different types of steel, both supplied by Böhler, an Austrian company which Extrema Ratio has been collaborating with for more than 20 years, using their time-tested materials to produce its blades.
MF1 EVO D BLACK, MF1 EVO D TACTICAL GREY and MF1 EVO SP TACTICAL MUD are made of Böhler N690, hardened to 58 HRC for better balance between edge retention and strength; this type of steel is used for most of Extrema Ratio knives.
For MF1 EVO D BLACK SATIN M390, MF1 EVO D RED SATIN M390 and MF1 EVO SP BLACK M390 versions, Extrema Ratio uses 61 HRC heat-treated Böhler M390 steel; thanks to a powder metallurgical production process, it guarantees cutting efficiency, resistance to wear and oxidation over time.
MF1 EVO offers two blade profiles, each suitable for different contexts of use. The drop point blade is ideal for those looking for a versatile and precise knife, particularly suitable for urban and outdoor environments. Its balanced shape and rounded tip make it a good choice for everyday activities, such as cutting lightweight materials or handling small emergencies, ensuring a good compromise between robustness and manageability.
The spear point blade is particularly suitable for tactical environments, where high penetration and robustness are required. Its central and sharp tip makes it ideal for dealing with more demanding situations, where precision and control are essential for effective operation.
