Sport, Military and Collectible Knives | Coltelleria Collini

The lines are stripped down to the essentials; the profile is clean and continuous. This isn’t an aesthetic choice, but the result of a function-oriented design. Every element exists for a specific reason; everything else has been eliminated.

The skeletonized full-tang construction and 4.8 mm blade thickness reflect a different approach: lightness where needed, strength where it counts. The 80 mm blade and 191 mm overall length define a compact yet uncompromising tool.

The AERO FX is built around materials selected to ensure durability, reliability, and minimal maintenance: an Anticorodal aluminum handle and a Nitrogen steel blade with a MIL-C-13924 burnished finish, designed to offer corrosion resistance, good edge retention, and ease of resharpening.

The carrying system consists of a dual-configuration Kydex sheath: an ultra-flat, slim solution for discreet carry and an additional interface to expand attachment options. The configuration can be adapted using the Malice clip or paracord, both of which are included.

When you need more working space and a blade with more substance, SATRE FX is the answer. It takes the essential design of the Satre and scales it up, improving control and cutting capacity without compromising its ergonomics. It is designed for continuous use, where the hand must not tire and the tool must remain predictable.

SATRE FX is a full-tang fixed blade with a skeletonized frame, designed to maintain good balance even during extended sessions. The more generous geometry offers a larger cutting surface and more stable handling during demanding tasks. The open construction also allows you to customize the handle with Paracord, adapting it to your preferences. The knife comes with a black Kydex sheath, pre-shaped and ready to use.

Configurations and Steels
* N690Co (Black and Stone Washed): a balanced choice between edge retention, impact resistance, and ease of use in the field.
* Nitrogen (Orange and Yellow): greater corrosion resistance, easy resharpening, and high visibility.
* Böhler S600 (Black): high-performance steel, cryogenically treated to 64 HRC, designed for maximum edge retention.

SATRE F è un chiudibile compatto pensato per uso quotidiano. Mantiene l’impostazione robusta della linea SATRE in un formato tascabile, con ingombri ridotti e portabilità reale. Sta in tasca senza dare fastidio, ma quando serve è pronto.

Apertura flipper rapida e controllabile con una mano. Struttura con doppia cartella in acciaio e blocco Liner-Lock: rigido, affidabile, senza giochi. La clip deep carry lo rende discreto in tasca. La fresatura sulla guancetta non è solo estetica: permette di identificare subito la variante anche da chiuso.

Le versioni in Böhler N690Co (Black, Stone Washed) puntano su resistenza all’usura e buona tenuta del filo, con manutenzione semplice. Le varianti in acciaio Nitrogen (Periwinkle, Orange, Yellow) privilegiano la resistenza alla corrosione, ideali per ambienti umidi o uso intensivo all’aperto. La versione Outdoor Nitrogen è la più orientata all’impiego sul campo.

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.

VIPERA is born from the fusion between the tactical and survival worlds, combining speed of use, robustness, and precision in a knife weighing less than 100 grams. Equipped with an elongated drop-point blade with a full flat grind and narrow edge, it offers penetration, smooth cutting, and hardness up to 61 HRC. It is available in two high-performance steels, both with excellent edge retention and corrosion resistance. The ergonomic handle with integrated guard ensures maximum control in all conditions, while the ASPIS nylon sheath allows for stable and versatile carrying.

VIPERA Nitrogen (Stone Washed, HCS, Ranger Green)
This variant is designed for outdoor, survival, bushcraft, and prepping users: areas where reliability in the field, weather resistance, and maintainability are essential. Nitrogen steel maintains excellent edge retention, combined with excellent rust resistance and, above all, greater ease of resharpening compared to M390. The increased resilience makes these models more tolerant to the abuse typical of a field environment.

Technical insight into nitrogen-added steels
Nitrogen steels, or nitrogen-added steels, are alloys in which nitrogen is used as an alloying element instead of, or in addition to, carbon. Although nitrogen is less effective than carbon in hardening the martensitic matrix, it has the advantage of forming stable compounds with chromium to a much lesser extent. This allows a greater amount of chromium to be kept in solid solution, improving corrosion resistance. In addition, nitrogen contributes to the hardness and stability of the structure, giving these steels a good balance between hardness, toughness, and corrosion resistance. Compared to traditional martensitic steels, nitrogen steels can therefore offer a better combination of mechanical properties and resistance to chemicals, while maintaining good workability and sharpenability characteristics.

 

Intended use: Outdoor / Utility / Bushcraft

Type of production: Industrial
Country of production: Italy
Blade: nitrogen-alloyed stainless steel
Blade treatment: Stonewashed
Handle: Forprene
Blade length: 116mm.
