Extrema Ratio has applied its rigorous military standards to a series of professional kitchen knives.

The blade is made of tested BOHLER N690 steel, enriched with chromium, vanadium, molybdenum, and cobalt, hardened to 58HRC. The handle is made of Forprene, an elastomer that meets NATO standards for resistance to extreme conditions and is fully removable from the blade, allowing for thorough cleaning and maintenance.

Each knife comes with its own sheath, also derived from military equipment. While not designed to meet hygiene regulations, it ensures safe transport of the extremely sharp blade and protects it from impacts that could reduce its efficiency. We recommend using the sheath only for transportation and long-term storage.

The name "Mato Grosso," comes from Portuguese and means "dense bush," recalling the South American region of the same name. This machete is specially designed to cut through the dense vegetation of tropical forests due to its long, narrow blade. It can be used to cut tall, dense grass, thin vegetation, cut branches and open paths in the most inaccessible forests.

Its forprene handle makes it easy to use. The drop blade, milled from Böhler N690 steel hardened to 58 HRC for the best balance of edge hold and strength, is 309 mm long, 4 mm thick and has a flat edge.

Mato Grosso comes with a black Cordura sheath equipped with an M.O.L.L.E. system that allows it to be carried on tactical vests and belts.
