HISTORY
The Tengu takes its name from a mythical creature of Japanese folklore that is represented with both human and raven features, they had the reputation of being great warriors and legends say that some founders of martial arts were trained by them.

- It is designed to be used in many different grips, but is especially effective in the reverse grip.
- Designed to be carried in a variety of ways, whether as a neck knife, under shirt, clipped in a pocket or around the waist using optional systems such as Ulti-Clip or Tek-Lok or various M.O.L.L.E. type attachments.
- With its thickness of 5.5 mm. is extremely robust and thanks to the shape of the handle is comfortable even by those with large hands or those who want to use it with tactical gloves.
- The blade is compact, robust and very functional for both precision cutting and hard materials thanks to the serrated part on the back. The tanto-shaped tip is very robust and optimal for engraving work.

Japanese steel merges with Italian excellence

For this 2021 collaboration, exclusive to Coltelleria Collini, we have decided to propose a series of best sellers produced by Extrema Ratio. 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 but 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.

Intended Use: Neck Knife / Collector's Knife

Type of production: Industrial
Country of Production: Italy
Blade / Handle: Full, laminated Japanese steel (San Mai) with V-Toku2 (carbonaceous) cutting edge at 62/63HRC and SUS410 (stainless steel) outer cheeks
Blade finish: Satin finish
Blade length: 40mm.
Blade thickness: 3mm.
Total length: 129mm.
Weight: 55g.
Sheath: Kydex, for neck.
Packaging: Cardboard box with Extrema Ratio logos.
Notes: Numbered edition - cardboard box with Extremaratio logos and certificate - the central core of the blade and handle is made of carbon steel so it is recommended to wash/dry the knife very well after each use and protect the steel, during storage, with a light surface of lubricant to avoid rust and oxidation.

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 also 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 individually taken:

- 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.

- Greater resilience
Built on the principle of Japanese swords, the 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 lateral coating (Stainless Steel).

- Improved corrosion resistance
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 damask pattern at the end of the processing are aesthetically elegant, refined and highly appreciated by collectors all over the world.

With the DOVO Stainless Satin Finished Straight Nose Scissor, 4", you can easily and painlessly remove annoying nose hair. We have rounded the tip of the scissors to give you a comfortable, painless experience when trimming in the sensitive nasal cavity. The DOVO blades have been precisely finished using hand-grinding to guarantee accurate cuts every time. Painful hair trimming is finally a thing of the past!

Material

This instrument is made of 1.4034 stainless steel. The metal alloy shows good corrosion resistance against soap or moisture and is therefore ideal for the production of high-quality scissors. In addition, the material has good cutting properties and can be ground precisely. The high-quality matte surface can be gripped safely even with wet hands.

Grind

DOVO scissors are finished and honed by hand. One of the challenges in the production of high-quality scissors is the precise dressing of the scissor blades. In order to guarantee maximum precision, our expert grinders hand grind every pair of scissors at the cutting edge and tip.

Product Details

Infections and injuries in the nasal cavity can not only be unpleasant but also dangerous. The nose has a sensitive nasal mucous membrane and thin veins, which can be quickly injured with a pointed tip. The ball-point tip is a particularly safe shape that protects you from such risks. The ball-shaped tip is blunt and generously rounded at the front, so that you can work without injury or worries. Usage you can easily and painlessly remove annoying nose hair
