* Checked and certified by our in-house laboratoryDirectly derived from military specifications, this folding knife is designed to replace a fixed blade in the most demanding operational situations. To ensure maximum reliability, extremely robust materials, increased thicknesses, and a solid and secure back lock opening/closing system have been used.
A manual safety lock ensures maximum protection during use, drastically reducing the risk of accidental closure. When inserted in the closed position, it also prevents the knife from being immediately used against the operator in the event of theft.
Materials and workmanship
All components are machined from solid blocks using high-precision CNC machines, while assembly, adjustment, and sharpening are carried out by hand. The blade is made of N690 cobalt stainless steel, known for its high mechanical strength, great cutting ability, edge retention, and excellent corrosion resistance. It has a flat grind and a hardness of 58 HRC.The scales are made of Anticorodal, an aluminum alloy that is highly resistant to stress and oxidation. The tang, made of hardened N690, acts as an effective emergency glass breaker. Screws, pins, and clips are made of burnished stainless steel, while the blade, lever, and tang are protected by Testudo treatment, which is highly resistant to abrasion and oxidation. The scales are black anodized.

Wander Tactical - Raptor knife - SanMai V-Toku2 & Green Paracord - kydex brown - custom knife
Japanese steel blends with Italian excellence
For this 2019/2020 collaboration, exclusive of Collini Cutlery, we have decided to propose a series of best sellers produced by Wander Tactical. Knives made with the famous San Mai steel produced by the Japanese Takefu Steel. Specifically, we used V-Toku2 carbonaceous at 62 / 63HRC for the central plate and SUS410 stainless steel for the two external plates, in order to guarantee a very high cutting capacity, penetration and sealing of the wire together with an easy regrinding and maintenance but at the same time the blade has a remarkable resistance to corrosion and an important increase in resilience given by the type of external steel and by the laminated structure.
RAPTOR model:
Use: Tactical / Utility
Type of production: Artisan

Blade: integral, laminated Japanese steel (San Mai) with V-Toku2 (carbonaceous) cutting edge at 62 / 63HRC and SUS410 (stainless steel) external scales

Notes: Each knife is unique and handcrafted - Wander Tactical certifiedAs in the ancient Japanese Samurai swords.
The rolled steel - imported into Italy by Collini Steel directly from the Japanese Takefu Steel - is based on the ancient Japanese tradition in the creation of the famous Samurai swords. In fact, as early as 1100 the expert Japanese blacksmiths combined different materials together to give the Katana swords incredible cutting abilities combined with a resistance and flexibility previously unknown. It is thanks to this revolutionary construction technique that Samurai swords have been preserved to this day, becoming one of the most fascinating objects made by man. Following this tradition applied to modern metallurgy, today we are able to have technologically advanced steels already tested and used in cutlery also by famous brands such as Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, etc.
Characteristics of San Mai steel: These are different types of metals bonded together to create a composite that encloses and intensifies the strengths of the metals individually taken:
- Longer life of the cutting edge
thanks to the use of very high quality steels with high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the heart of the sheet (Core Steel), the blade, once hardened, achieves decidedly hardness and cutting performance higher than those achieved with the use of traditional steels.
- Greater resilience
built on the principle of Japanese swords, multilayer steel is difficult to break thanks to the toughness of the central steel (Core Steel) and the elasticity of the steel used for the side facing (Stainless Steel).- Better corrosion resistance
the steel used for the external layers (Stainless Steel) guarantees the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates, on a galvanic level, a structure that improves corrosion resistance even on the wire.- Easy processing even after heat treatment
although the steel normally becomes harder after hardening, the side steel used in multilayer processing does not lose its softness and allows easy processing, drilling or welding even after heat treatment. For an optimal performance of the blade, cryogenic treatment is recommended.- Improvement of the aesthetic result
The knives made with multi-state steel or damascus pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.For more information: collinisteel

FULCRUM C model: for this First Production Run, a circulation of 10 pieces numbered from 1 to 10 was produced.
FULCRUM C is the compact version of FULCRUM, it maintains all the characteristics of solidity and robustness and, thanks to the reduced dimensions of the blade (only 110 mm) and the handle, it is easily portable and concealable. The rigid sheath can be positioned horizontally, vertically or in a 45 ° inclined position. The only safety of the sheath is automatic with extraction and re-insertion by pressure, this detail makes it an intuitive and extremely fast tool, particularly suitable for emergency use and for personal defense.
