Extrema Ratio BF1 Classic Drop, pocket knife

The **Extreme Ratio Kiri** was inspired by the Japanese Kiridashi, which is originally a marking knife, used by craftsmen like carpenters and furniture makers. One of its peculiarities is its asymmetric bevel; only one of the two sides is sharpened, while the other remains flat. Extrema Ratio has reinterpreted this traditional Japanese knife according to their own style, giving it a more tactical look than the original. The Kiri has a special point designed for precision, while maintaining its distinctive chisel-shaped grind.




The blade of the Extrema Ratio Kiri 04-10000187SAT Satin, fixed knife measures 6,7 cm in length and 4,8 mm in thickness. The total length is 19,1 cm.



## Blade made of Böhler N690 steel
The blade of the Extrema Ratio Kiri 04-10000187SAT Satin, fixed knife is made of Böhler N690, a very corrosion-resistant steel from Austria. It is tough and easy to sharpen, even with relatively limited resources. Needless to say, it retains its sharp edge very well.



The blade of this knife is enhanced with a 'satin finish'. This is a chic and tasteful finish that is very popular.



## Handle made of aluminium
This Extrema Ratio Kiri features a handle made from aluminium. Aluminium is very lightweight and easy to machine. This makes it a popular choice for handles. Aluminium comes in many different grades or alloys. For knife handles, most manufacturers use one of the more durable grades, often the same grades used for building aircraft.



The Extrema Ratio Kiri 04-10000187SAT Satin, fixed knife comes with a sheath made of kydex, a sturdy plastic that will keep the steel safe. However, it is important to keep a kydex sheath clean on the inside. Rinse it regularly with water. This will prevent dirt from remaining in the sheath, which can scratch the blade.



## History of Extrema Ratio
Extrema Ratio was founded in 1997 in Italy. The brand has become famous in the knife world with their tactical knives for the military, police officers and firefighters. The knives, often produced in collaboration with the Italian army, meet the highest military standards. They use materials such as Böhler N690 stainless steel and Forprene handles for comfort and safety, even in extreme conditions.

The range varies from fixed knives like the Requiem to rugged pocket knives like the BF2. Extrema Ratio is ISO 9001 certified and also supplies international military units. Their products are popular among adventurers and professionals worldwide for their reliability and durability. Many of the Extrema Ratio products originate from demand from a government department. In collaboration with that department, they develop a practical knife, a real tool. After this, it is available to everyone, for example here at Knivesandtools.
