ExtremaRatio - Satre - Yellow Nitrogen - Fixed-Blade Neck Knife
SATRE is a compact fixed-blade knife developed in collaboration with Daniele Dal Canto, a guide with the AIGS (Italian Association of Survival Guides). It was created to deliver high performance in a compact format, designed for survival, bushcraft, urban use, and as a backup tool. The range has been updated with new variants in high-visibility Nitrogen steel.
SATRE features a skeletonized full-tang construction that allows the handle to be wrapped in Paracord, adapting it to the user’s needs. Its compact size and the pre-formed black Kydex sheath, equipped with metal eyelets for ambidextrous, vertical, or horizontal carrying configurations on various mounts, make it suitable for use as a neck knife, backup knife, or primary tool in a survival kit.
The range now includes versions in Nitrogen steel (Orange and Yellow), characterized by high corrosion resistance, ease of resharpening, and high visibility in the field.
These are joined by models in N690Co steel (Black, Expeditions, and Stone Washed), a historic benchmark of the series for its overall balance between performance and operational handling, and the variant in Böhler S600 steel (64 HRC), designed for maximum hardness and edge retention.

Fallkniven - U2 Folding Knife - Hercules 2026 Limited Edition - Satin Elmax & Black Grilon - folding knife
The new U2he is the 2026 collector’s edition of the famous U2 folding knife, now featuring an Elmax steel blade and adorned with a laser-engraved image of the constellation Hercules on the right side of the blade.
Elmax steel, produced in Sweden using powder metallurgy technology, is known for its excellent balance of strength, edge retention, and durability. It is a complex and expensive material to work with, requiring advanced skills and meticulous craftsmanship.
The slim handle, made of high-strength composite material, makes the knife lightweight and comfortable to carry. The “nail nicks” on the blade allow for easy opening by both right- and left-handed users, while the traditional lockback mechanism ensures a solid and reliable closure, with the characteristic safety “click.”
The constellation Hercules, known as “Hercules,” is one of the largest in the northern sky and represents the Greek mythological hero. Although it lacks stars of the brightest magnitude, it is easily recognizable thanks to the “Keystone” asterism, a quadrilateral of stars that defines its central body.
After selling tens of thousands of U2 models, it’s easy to see why this lightweight, razor-sharp knife remains one of the most popular. Since 2004, the U2 has been the world’s first folding knife with a powder-coated steel blade, a combination that has demonstrated exceptional performance in terms of extreme sharpness and durability.

Fallkniven - U2 Folding Knife - Virgo 2025 Limited Edition - Satin Elmax & Black Grilon - folding knife
The new U2vi is the 2025 collector's edition of the famous U2 folding knife, now made with an Elmax steel blade and embellished with a laser engraving of the Virgo constellation on the right side of the blade.
Elmax steel, produced in Sweden using powder metallurgy technology, is known for its excellent balance of strength, edge retention, and durability. It is a complex and expensive material to work with, requiring advanced skills and careful craftsmanship.
The slim handle, made of high-strength composite material, makes the knife lightweight and comfortable to carry. The bilateral serrations on the blade allow for easy opening for both right- and left-handed users, while the traditional lockback mechanism ensures a solid and reliable closure with a characteristic safety “click.”
The constellation Virgo, “The Virgin” in Latin, is the second largest in the sky and the largest of the twelve zodiac constellations, recognizable by its brightest star, Spica.
After selling tens of thousands of U2 models, it is easy to see why this lightweight, razor-sharp knife remains one of the most popular. Since 2004, the U2 has been the world's first folding knife with a powder-laminated steel blade, a combination that has proven to deliver exceptional performance in terms of extreme sharpness and durability.
