LKU01 Urban Sideral

The Extrema Ratio LKU01 Urban Sideral is a fascinating symbiosis of modern functionality and Italian craftsmanship. Developed in collaboration with Danilo Rossi Lajolo di Cossano, this compact folder impresses with its well-thought-out design and tactical versatility.

The 10 cm blade made of hardened Böhler N690 steel with a hardness of 58 HRC ensures stability and durability for demanding applications. With its sandblasted finish, the blade of the Urban Sideral has a subtle, matte sheen that is both unobtrusive and resistant to reflections, reinforcing the urban character of the knife. The flat blade also ensures excellent cutting properties.

One highlight is the clever design without classic cross-guard, which prevents catching on clothing and allows quick access when needed. The reverse cross-guard on the blade provides additional protection and prevents unintentional folding – particularly valuable in tough applications.

The handle, made of robust anticorodal aluminium, has a fine pinstripe pattern that ensures both visual elegance and a secure grip. Even with intensive use, the Urban Sideral always remains secure in the hand. The quick-release mechanism, inspired by a bullet casing, allows the blade to be opened in a flash with one hand, making the knife the ideal companion for tactical and urban situations.

The design is rounded off by the removable, reversible horseshoe-shaped stainless steel clip, which is reminiscent of Italy's historic martial tradition and gives the knife a special charm. With a total length of 22.3 cm and a weight that is perfectly suited to the demands of everyday use, the Extrema Ratio LKU01 Urban Sideral is the perfect choice for modern adventurers and lovers of Italian precision and style.
