Danilo Rossi is a very interesting figure of the martial arts world. A direct descendant of the Lajolo family of Guelph and Gibelin, he is an Italian nobleman of the Lajolo family and the son and nephew of the Counts Lajolo Cossano of Piedmont, Italy. A stuntman, a raconteur, a lover of good cigars and whiskey, and a passionate champion of traditional Italian knife fighting methods. Based on his experience, he created the Lajolo di Cossano style, which combines elements of traditional fencing with a modern way of fighting. Limited production of the knife designed by Danilo Rossi was undertaken by one of the icons of the knife world, the company Extrema Ratio. In this way, the tradition of fighting knives was combined with contemporary design, and the whole thing produced a great effect!

N690 - corrosion-resistant, high-carbon 1.07% (C), martensitic chromium steel 17.30% (Cr) with the addition of molybdenum 1.10% (Mo), vanadium 0.10% (V) and cobalt 1.50% (Co) for structural uniformity. Features exceptionally high corrosion resistance and long edge retention. One of the best tool steels in the world today. Achieves a hardness of 58 HRC. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.

Blade - classic spear point, with a high flat grind that will provide excellent cutting properties. A “false blade” has been added at the top, making the knife much easier to penetrate any material. It opens with a disk (thumb disc) on the back of the blade, which allows seamless use by both right and left-handed people . The blade has been sandblasted. The whole is locked with a proven and popular liner lock.

Handle - is polished aluminum. The surface is decorated with graphic elements, referring to the horseshoe in honor of the Italian warriors of the 800s and 900s, who used various luck-bringing objects, including this symbol. The grips have been bolted to a steel skeleton, which together gives the structure tremendous strength. Instead of a standard backspacer, there is a spacer in the back between the skeleton of the structure . This solution provides easy access to the interior, which is of considerable importance when cleaning the knife in the field. A two-position (right/left) stainless steel clip allows us to carry the knife in tip-down position .
