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.
