EXTREMA RATIO – SATRE BLACK – BLACK BOEHLER N690 + KYDEX
Satre is a pocket-sized, light and extremely resistant fixed blade knife. Given its characteristics, it can be employed in a large variety of activities and fields, including survival and bushcraft, or it can be part of an EDC kit (Every Day Carry). It was designed in collaboration with Daniele Dal Canto, a Master Advanced F.I.S.S.S. instructor (Italian Federation of Sport and Experimental Survival). It can be worn as a neck knife thanks to its Paracord 550 lanyard. This way, it is possible to keep it vertical with the handle facing down. The pre-shaped Kydex sheath has eyelets, allowing to apply both lanyard and accessory holder.

To obtain the development of products with a high level of performance, our prototypes and samples undergo the strictest NATO tests, integrated with other more specific and even stricter tests carried out inside our laboratory. To ensure a real and absolute efficiency, we execute comparative tests with the most representative products from other firms in this sector.
Extrema Ratio uses N690 – 58 HRC Stainless Cobalt Steel in the large majority of its knives because the additional cobalt content adds strength to the blade. Suffice to say that the type of steel used to make Extrema Ratio knives makes them quite unique and very strong. The metal content of that “stainless cobalt steel” has been specifically calculated to provide steel that would hold an edge well without being so brittle that it might fracture easily – or easier than competitor knives. What make the steel unique are the higher levels of chrome and cobalt than normally found in most other steel alloys.
With the co-operation of the Facoltà di Scienze Motorie of the University of Perugia Extrema Ratio has developed a special handle called ERMH (Extrema Ratio Multipurpose Handle). The grips are a single piece cut to comfortably fit the user hand to help in maintaining a secure grip even under wet, sweaty or bloody conditions. The use of Mil-spec materials for the handles like Kraton, Forprene and special polymers add extra quality details to the final product.
