ExtremaRatio - RAO C - N690Co & Aluminum Black - folding knife
Thanks to its structure, RAO C is a tool that despite its small size, manages to guarantee the same qualities of robustness and reliability as its big brother while offering better portability and manageability.
The locking mechanism on opening is particularly strong as it is assisted by a safety system that turns it into a true fixed blade. The primary safety on the blade is activated by raising and lowering the locking pin. To provide the user with maximum safety in use, a practical and quick secondary safety has been applied, which can be activated simply by moving the locking pin horizontally.
For the purpose of lightening the steel frames, a template was laser-cut from the profile of the RAO C, which was then used to make a gadget that is delivered with the knife.

ExtremaRatio - Sethlans Expeditions - Survival Knife - knife
Sethlans Expeditions, as well as the Sethlans model from which it derives, is a fixed blade work knife designed to deal with a wide range of situations, but also as a backup blade. The Sethlans Expeditions has been designed in collaboration with Daniele Dal Canto, Master Advanced F.I.S.S. (Federazione italiana survival sportivo e sperimentale) instructor.
Sethlans Expeditions has a Böhler N690 steel blade heat treated to 58 HRC with MIL-C-13924 burnishing and stone washed surface treatment (Dark Stone finish). The knife comes with desert colored G10 grips that feature the ergonomic design characteristic of Extrema Ratio handles. They can be removed to free the skeleton structure of the knife, allowing maximum lightness with minimum thickness.
For lovers of extreme customization, the full-tang structure allows the handle to be covered with paracord. The sheath is composed of a very light and minimalist Kydex part. It can be disassembled and can be adapted to both left- and right-handed people. The addition of an optional belt clip allows both vertical and horizontal positioning of the knife and makes the sheath much more versatile than the textile version.

ExtremaRatio - Resolza 10 - Stone Washed - pattada knife
RESOLZA, a term of ancient origin, is today one of the most famous traditional knives of our country. The name suggests the razor by chance.
It was born in Sardinia centuries ago and has accompanied its inhabitants until today in the daily work of a peasant and pastoral life, following them even when its men were called to war. The chronicles of the Sassari Brigade during the First World War cite this knife among its soldiers' equipment.
We wanted to make a tribute by revisiting it according to our canons, without wanting to hurt any of the prestigious Sardinian artisans who still today pass on the tradition and wisdom of their ancestors. The dimensions and proportions are the original ones of a 10 cm blade, but the materials and technologies are those of our production. The handle revised in our style, the blade most faithful to tradition. In addition to the original, it has the blade lock open.

The blade is made of Böhler N690 steel, hardened to 58 HRC and is 116 mm long, 5 mm thick and equipped with a flat edge. The profile of the blade is of the modified spear point type, with a false counter-thread ¾ in length on the back and a lower guard to protect the hand during use.
Both the guard and the knob have holes to facilitate the attachment of the knife to various tools or for the passage of laces. The blade has a Carbon-based DLC (Diamond-Like Carbon) surface coating making it hyper-resistant to abrasion and chemical aggression.
Given the heavy use of the tool, for the handle, instead of the usual Forprene, the more performing high-strength G10 is used.
