  1. ExtremaRatio - K1 Dobermann knife - XXV Anniversary - Limited Edition

    This special edition in 250 pieces, proposed on the occasion of the 25th anniversary of the brand, maintains the shape of the original, but with materials and finishes corresponding to the current production.

    The K1 is equipped with a modified spear point profile blade, characterized by a tip that combines the 40° "tanto" profile with the more traditional European one, creating a sharp but very solid hybrid which, with the false false edge, makes it particularly effective in jab. The bevel is high, allowing for a very effective cutting angle.

    The blade is immediately recognizable by the fenestration at the heel, which allows for considerable lightening without compromising its strength. It is made of Böhler N690 steel, with heat treatments that bring its hardness to 58 HRC for the best combination of edge hold and resistance. The finish is satin with flat grinding.

    The handle, in anodized Anticorodal alloy, compared to the original presents the lightening on the sides that make the Extrema Ratio knives immediately distinguishable, but maintains the arched shape and the lateral "bellies" of the K1, offering an excellent grip both in the "saber" than in the "reverse" grip.

    The terminal part of the handle curves to form a sort of hook which allows particularly easy and rapid extraction from the scabbard, while the tang protrudes from it with a triangular cusp which acts as a glass breaker with a slot which allows the knife to be equipped of lasso.

    The leather scabbard faithfully reproduces the original while maintaining both the qualities of ease and speed of extraction. The carry can take place in an upside-down axillary position, horizontally on the belt or tactically on the thigh.

    The K1 equipment is completed with a polypropylene case ‌, complete leather sheath and underarm shoulder strap.

  2. ExtremaRatio - Kreios Expeditions - Heavy Utility Machete - Knife

    Kreios Expeditions, as well as the Kreios model from which it derives, has been designed and developed thanks to the collaboration with the Master instructor F.I.S.S. (Federazione Italiana Survival Sportivo e Sperimentale) Daniele Dal Canto. It is defined by its creator as a sort of "off the road" of cutting tools, therefore not a specific disposable tool, but a multi-tasking tool, extremely versatile and designed to cope with many uses.

    Thanks to its ergonomics, weight and size, Kreios Expeditions is suitable to open gaps in the thick vegetation, especially where it is necessary to take distance, for safety reasons, from thorny or harmful essences. Thanks to its robustness, it is an effective machete even in the heaviest field work. Combining the 32 cm of the "full flat" cutting edge, the 11° forward inclination of the blade and the 630 gr. of its weight, you get a tool with extraordinary cutting capabilities that does not fear bending.

    Kreios Expeditions brings modern geometry and materials combined with the lines and effectiveness of blades typical of the Malaysian and African tradition, creating an ideal tool for field work but also, if necessary, for defense/offense. Kreios Expeditions is equipped with a desert color forprene handle and a BÖHLER N690 (58HRC) steel blade with MIL-C-13924 burnishing and stone washed surface finish (Dark Stone finish). It is supplied with a desert Cordura sheath with MOLLE system and strap for safety carry, equipped with a mini pouch containing paracord with flammable filament to be used in case of emergency and/or critical weather conditions and a Firesteel for lighting fires.
