The **Extrema Ratio Fat Boy Satin, 04.1000.0107/SAT-BLK** is the most robust fixed knife ever produced by this brand. Made from N690 steel with a hardness of 58 HRC, a thickness of 8.6 mm and a weight of 1 kg, this knife combines impressive thickness with clever design. This design was inspired by the first cleavers, that have been used since ancient times.

The Fat Boy is known for its excellent wear resistance and versatility, making it ideal for both heavy-duty tasks like splitting wood as well as opening windows or doors in case of emergency. Its generous size and unique features make outdoor activities such as chopping and cleaving fun and easy. The blade has as completely flat grind and a tip that functions as protection as well as a lever. Thanks to its shape and width, it is even possible to dig small holes in the ground in emergency situations. The thick and flat back of the blade adds extra mass and can be used as a ‘hammer’, e.g. for tent pegs.



The blade of the Extrema Ratio Fat Boy Satin, 04.1000.0107/SAT-BLK, fixed knife measures 22.6 cm in length and 8.5 mm in thickness. The total length is 34.7 cm.



## Blade made of Böhler N690 steel
The blade of the Extrema Ratio Fat Boy Satin, 04.1000.0107/SAT-BLK, 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.



This knife has a convex grind. This is a special sharpening method where the side of the blade continues in one convex curve to a razor-sharp edge. This sharpening method is often applied by hand in the factory. The great advantage of a convex grind is that it offers the perfect balance between minimal cutting resistance and optimum strength of the edge. You maintain a convex edge [by stropping it]/en/ct/stropping.htm).



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



## G10 handle
The Extrema Ratio Fat Boy Satin, 04.1000.0107/SAT-BLK, fixed knife features a handle made from G10. This is a composite material made of glass fibre and synthetic resin. It is very strong, offers a lot of grip and is comfortable to hold. Moreover, it is not affected by moisture and it is a very stable material. It's an excellent choice for the handle of a fixed 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.
