Technical analysis of characteristics and features
Blade steel: S390
S390 high―speed powder steel is one of the most modern and technologically advanced steels on the market. It is characterized by extremely high hardness of 70 HRC, outstanding wear resistance and long-term preservation of the cutting edge even during intensive operation. Due to the high content of cobalt, tungsten and vanadium, the blade demonstrates excellent resistance to abrasion and aggressive materials. S390 has high corrosion resistance, allowing the knife to be used in a humid environment and in contact with food without fear of rapid rust, however, like any highly alloyed steel, it requires regular maintenance to prevent corrosion.
Handle material: stabilized Karelian birch and black hornbeam with nickel silver
Stabilized Karelian birch is a natural wood treated with special compounds to increase strength, moisture resistance and preserve a rich, unique pattern. Black hornbeam is known for its density, durability and resistance to humidity fluctuations, which makes the handle not only beautiful, but also extremely reliable in everyday and extreme use. Inserts made of nickel silver add status to the product, strengthen the handle and provide additional protection against mechanical damage.
Blade shape: clip-point
The classic clip-point shape provides a thin, sharp tip and increases control when performing delicate work: cutting, thinning, and skinning. The blade width of 30 mm and length of 142 mm allow you to comfortably perform a wide range of tasks — from precise to more forceful cuts. The 2.4 mm thickness of the butt makes the knife strong enough, while not creating excessive weight.
Retention and ergonomics
The 120 mm long handle provides a secure grip, both in the bare hand and in the glove. The texture of stabilized birch and the smoothness of hornbeam are non-slip even in wet conditions or prolonged operation. The balance of the knife is shifted to the handle, which prevents rapid fatigue of the brush.
Wear and maintenance
The S390 requires minimal sharpening — the cutting edge lasts extremely long even when cutting hard materials actively. However, due to the hardness of the steel, the sharpening process requires high-quality abrasives (diamond or ceramic) and some experience. The handle is resistant to moisture, but it is recommended to avoid prolonged exposure to water and wipe after use.
Scope of application, advantages and limitations
- Optimal tasks: hunting (butchering, skinning), hiking, working with wood and products, universal vole, collection purposes.
- Excellent retention of sharpness even under intense stress — ideal for long expeditions and multi-day use.
- Resistance to moisture and mechanical stress due to the complex structure of the handle and high-grade powder steel.
- Limitations:S390 is an extremely hard steel that requires special sharpening skills and the use of specialized tools. It is not recommended to use a knife for heavy work, which involves significant lateral load or bone work. It is not intended for batoning on thick branches and heavy chopping.
Unique features and competitive advantages
- Rare alloy steel S390, which brings the knife to the level of a premium tool for the most demanding users.
- The combination of two noble woods and nickel silver makes the knife not only practical, but also collectible and aesthetically valuable.
- Traditional handmade — each piece is unique, with a unique birch pattern and author's processing of details.
Care recommendations
After use, rinse thoroughly and wipe dry. For the blade, periodically apply a thin layer of mineral oil, especially during long—term storage. Sharpen only on modern diamond/ceramic bars. The handle can be treated with special wood oils to preserve its shine and color saturation.
Final recommendation
This knife is ideal for hunters, tourists, collectors and connoisseurs of original hand tools, who value the outstanding resistance to wear, cutting, aesthetics and uniqueness of each piece. It is not suitable for beginners without the skill of servicing carbide blades and is not intended for heavy chopping on bones and twigs. The choice is for those who appreciate not only the working potential of a knife, but also the subject art.
