Folding knife Extrema Ratio MF0 D Black Rough 04.1000.0140/RVB 6.8cm
Sold out
Folding knife Extrema Ratio MF0 D Black Rough 6.8cm 04.1000.0140/RVB
Extrema Ratio MF0 D Black Rough folder is “the little one” amongst MF knives. Basically it is 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. This versione is produced with a rough handle for a better grip. The drop point blade 68 mm is made of Bohler N690 stainless steel (58HRC). Black aluminum handle. 
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. Overall length 181 mm. Weight 139 g. Made in Italy.

Diving knife Extrema Ratio Ultramarine Con Asola 15cm 04.1000.0320/BLK
Extrema Ratio ULTRAMARINE is an amphibious knife, carried around from underwater operation equipment (diving suit) to ground operation equipment (tactical vest). Can be shipped only inside EU. Two different versatile sheaths were therefore developed for it. The scuba sheath can be worn at the ankle, or its hard ABS section can be attached by two BELT-CLIPS to either the breathing apparatus or BCD belts. The land sheath (OPTIONAL, included on request) is MOLLE system compatible, designed to be attached to the tactical vest and carried inside a waterproof bag during underwater operations. All an operative has to do, if getting rid of his diving suit after landing, is to draw the knife from its ankle sheath and place it in the tactical vest sheath. Primary functions: field operations, underwater operations, emergency tool, survival and combat.

Extrema Ratio knives are a part of equipment of many special military units of Italy, the police and rescue services. Each model is developed very carefully and undergoes a series of rigorous tests before it is put into production. Extrema Ratio cooperates with the University of Perugia, where scientists conduct a number of studies determining the ergonomics of Extrema Ratio products and methods for improving it. The office of Extrema Ratio is located in Prato, Italy. Both Extreme Ratio tactical knives and EDC knives are distinguished by impeccable quality. Most knives are made of Austrian steel N690, which is famous for its high content of molybdenum and cobalt and is highly corrosion resistant. Due to this, N690 steel has increased strength and resists shock loads well. The most popular Extrema Ratio knives are Fulcrum, Col Moschin, RAO, Adra and others. Extrema Ratio also produces several lines of tactical folding knives: BF (basic folder), MF (medium folder), BD4, BD2 series and other knives. In our store you can buy Extrema Ratio tactical knives, as well as folding and EDC knives of this brand. MyGoodKnife is the official distributor of Extrema Ratio.
