Produced in Olean, NY, in collaboration with the skilled people at KA-BAR knives, the Spartan-Harsey Kukri knife has been designed to be a highly durable hiking knife. The kukri features a blade of over 22cm, making it an all-around tool due to its center of mass, allowing the user to slice while cutting to even penetrate thick objects.

While this blade is primarily famous for its military use, the kukri is more commonly employed as a multi-purpose tool in fields and homes across Nepal. Its uses range from construction, clearing, cutting firewood, digging, butchering animals for food, slicing meat and vegetables, skinning animals, to opening cans.

It can function as a smaller knife using the narrower part of the blade closer to the handle. The heavier and wider end of the blade, towards the tip, functions as a hatchet or a small shovel.

Exclusive knife in entirely handcrafted "Comix" coloration, part of a batch of products made especially for the Atlanta 2023 Blade Show.

"Comix" type coloring refers to a coloring technique used in comic books and illustrations that is inspired by the style of traditional comic books. This style of coloring often features flat, bright colors with sharp edges between different shades. Some hallmarks of comix-type coloring include:

Flat backgrounds: Areas of solid color are applied without shading or complex tonal gradations. This gives a more "clean" and stylized look to the image.

Sharp edges: The borders between different shades of color are often marked by black or dark contour lines. These lines define the boundaries of the various elements in the image and accentuate the contrast between the different colors.

Bright colors: In comix-type coloring, bright, saturated colors are often used to create visual impact. These colors can be used to distinguish characters or to emphasize certain elements of the image.

Simplified shading: Although comix-type coloring may include shadows and highlights to add depth, these are often simplified compared to other coloring techniques. Shadows may be represented by areas of darker color or simple lines or brush strokes.

Graphic effects: Some elements of graphic effects, such as dots or speed lines, can be used to accentuate action or movement in illustrations.

Knife withdrawn from a private collection - Limited edition production in Japanese CoS steel in SanMai dating back to 2018 and no longer available - In like new condition, no marks on the blade (never cut, never resharpened) or on the handle. Supplied with handmade Kydex sheath and Wander Tactical certificate - Checked and certified by our in-house Coltelleria Collini laboratory.

In collaboration with Wander Tactical we have decided to propose their new neck knife, the Raptor model, in an exclusive version with a satin blade that uses the famous Japanese San Mai steel produced by Takefu Steel. Specifically we used, for the central plate, the CoS at 61.5HRC (Cobalt Special, mechanically considered 25% higher than the already highly appreciated VG10) and the 420J2 (at 56 HRC) for the two side plates in order to guarantee a very high cutting capacity, but at the same time a remarkable resistance to abrasion, resilience and resistance to oxidation.

As 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 capabilities 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 with 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 coating (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, at the galvanic level, a structure that improves the corrosion resistance even on the wire.

- Easy processing even after heat treatment
although steel normally becomes harder after hardening, the lateral 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 with a damascus pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.

Japanese steel merges with Italian excellence

For this 2019/2020 collaboration, exclusive to Coltelleria Collini, we 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 have used the carbonaceous V-Toku2 at 62/63HRC for the central plate and the stainless SUS410 for the two external plates, in order to guarantee a very high cutting capacity, penetration and edge holding together with an easy resharpening and maintenance. At the same time the blade has a remarkable resistance to corrosion and an important increase of resilience given by the type of extreme steel and the laminated structure.

As in the ancient swords of the Japanese Samurai.

The rolled steel - imported in 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. As early as 1100, expert Japanese blacksmiths combined different materials to give Katana swords incredible cutting capabilities combined with previously unknown strength and flexibility. It is thanks to this revolutionary construction technique that the Samurai swords have been preserved until our days becoming one of the most fascinating objects made by man. Following this tradition applied to modern metallurgy, we are now able to have technologically advanced steels already tested and used in cutlery by famous brands such as Fallkniven, Cold Steel, Mcusta, Kai, Sog, Zwilling, Rockstead, etc.

Characteristics of San Mai steel: It is made of different types of metals alloyed together to create a composite that contains and intensifies the strengths of the metals taken individually:

- Longer cutting edge life
thanks to the use of high quality steels with a high carbon content (VG10, CoS, Shiro) or sintered (SPG2), in the core steel, the blade, once hardened, reaches hardness and cutting performance decidedly superior to those achieved with the use of traditional steels.

The steel used for the outer layers (Stainless Steel) gives the blade a high resistance to corrosion. The combination of the two or more materials used by Takefu Steel generates, at a galvanic level, a structure that improves corrosion resistance even on the edge.

- Easy machining even after heat treatment
Although steel normally becomes harder after hardening, the lateral steel used in multilayer machining does not lose its softness and allows easy machining, drilling or welding even after heat treatment. For optimum blade performance, cryogenic treatment is recommended.

- Improved aesthetic performance
Knives made of 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.

Selvans Expeditions, as well as the Selvans model from which it derives, was born from the collaboration between Extrema Ratio and the Master instructor F.I.S.S. (Federazione Italiana Survival Sportivo e Sperimentale) Daniele Dal Canto. This tool is the result of the modification of the ONTOS, military survival knife, realized in order to accentuate and maximize the performance of the knife.

Selvans Expeditions uses Böhler N690 steel heat treated to 58 HRC with MIL-C-13924 burnishing and stone washed surface treatment (Dark Stone finish). The handle has been lengthened and the blade weighted to promote effective cutting strokes. It comes with a desert Cordura sheath with MOLLE system, equipped with a mini pouch containing paracord with flammable filament that can be used in case of emergency and/or critical weather conditions and a Firesteel for lighting fires.

The survival kit (not included and purchasable separately) has been optimized and includes whistle, chainsaw, drinking pads, compass, brass wire, flintlock, flashlight, paracord 2,5 mt. and sharpener.
