Our restyled series of training knives are manufactured in a wide range of models of diverse size and shape. They enable martial arts practitioners and professionals to train different combat techniques with an appropriate and dedicated tool. All training knives are produced in a metallic blue colour which makes them easily identified even when sheathed. The blades are produced from anodized aluminum and have the very same shape and size of the Extrema Ratio standard production models. The handles are the same used in our production models. The sheaths, sold separately, are the same used for the real knives. The stiff blade allows for training complex defensive and disarming techniques. We recommend the use of appropriate protective gear when training.

extrema ratio fulcrum ii d desert warfare
(ref.: 04.1000.0151/DW)
Extrema Ratio Fulcrum Ii D Desert Warfare
Shipping 8-10 days
This model is the evolution of the FULCRUM Folder (out of production since 2005), the first folding knife produced by Extrema Ratio according to the specifics of an Italian counter-terrorism unit. The FULCRUM II is basically identical to its predecessor, the only variations being the addition of a reversible clip and a partially lowered surface on the handle which improves the ergonomics and makes operating the opening pin easier. A manual security lock holds the BACK-LOCK mechanism lever, preventing accidental unlocking of the blade block during heavy-duty use. It can also be used to lock the knife closed in the event it’s taken away from the user: then the FULCRUM cannot be opened, even if the mechanism is often irrevocably damaged. The back of the flat-ground blade offers a comfortable resting point for the thumb. The tempered steel tang can be used as glass breaker and is provided with a hole to affix a security cord. Available versions: FULCRUM II D BLACK, FULCRUM II D DESERT WARFARE, FULCRUM II D BLACK RUVIDO, FULCRUM II T BLACK, FULCRUM II T DESERT WARFARE, FULCRUM II T BLACK RUVIDO.

Extrema Ratio Nemesis Black
Shipping 8-10 days
The structure of the NEMESIS is similar to that of the M.P.C.. It is however more suitable for defensive use. The blade is quite thick and flat grinded, strong and sharp. The upper guard prevents the hand from slipping onto the blade. The long handle sticks out of the hand allowing the knife to be used for non-lethal blows. A manual security lock holds the BACK-LOCK mechanism lever, preventing accidental unlocking of the blade block during heavy-duty use. It can also be used to lock the knife closed in the event it’s taken away from the user: then the NEMESIS cannot be opened, even if the mechanism is often irrevocably damaged. The tempered steel tang can be used effectively as a glass breaker and sports a hole for a lanyard. A knife with a marked Italian character. Available versions: NEMESIS BLACK, NEMESIS BLACK RUVIDO, NEMESIS DESERT WARFARE.

MF stands for Medium Folder: a product line positioning itself between the BF (Basic Folder) and the Heavy Folder lines. MF knives employ the LINER-LOCK mechanism and are distinguished for their sturdiness; all are equipped with a glass-breaker. An innovative supplementary screw can be unlocked to enable fine-tuning of the main screw, adjusting opening speed to taste. Hemispheric milling marks on handles make it easier to change from saber-style to reverse grip. Clips are reversible. Model MF0 is “the little one” amongst MF knives – basically a compact version of the MF1. It retains all the characteristics of MF1 but has a downsized handle and shortened blade, similar to our SHRAPNEL “back-up” knife. Available versions: MF0 BLACK, MF0 BLACK ROUGH, MF0 DESERT WARFARE.

One of the most robust folding knives on the market, M.P.C. incorporates all the characteristics of the FULCRUM II, but its heavier blade enables more effective cutting blows, useful in field work.

A manual security lock holds the BACK-LOCK mechanism lever, preventing accidental unlocking of the blade block during heavy-duty use. It can also be used to lock the knife closed in the event it’s taken away from the user: then the M.P.C. cannot be opened, even if the mechanism is often irrevocably damaged.
